I used the metal body of my welder as a mounting surface (bridge rectifier inside, heatsink outside). Also used thermal paste for a better heat transfer. **Q: Is the current rated per one diode?** A: Generally in a DC circuit they are called diodes as the block and conduct in one direction. When (4) are connected in a full wave bridge in a single-phase circuit they are called a rectifier bank and in a car alternator there are (6) diodes in their full wave bridge. All the diodes in this full wave single-phase rectifier are rated for 1,600 volts and 200 amps. **Q: Will this work in reverse dc to ac and how?** A: This would not work to convert dc to ac. A rectifier uses diodes to allow the ac current to only flow in one direction, which results in a, basically, pulsating dc current. What you would need is an inverter, to convert dc to ac current, rather than a rectifier ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great for AC buzzbox to DC conversion *by on Reviewed in the United States February 9, 2024* Works great to convert AC welder to "pulsed" DC for cheap. You'll really want to find a microwave transformer to wind some wire to make a "choke" in the circuit after this rectifier, this will make more steady DC current. I went an extra step and used both a microwave transformer core (free) and a large ferrite toroid ($7) that I hand wound with 4AWG CCA ($14). The output is much smoother than AC with less spatter and actually runs 7018 rod nicely. I cheaped out and went with a 200 amp rectifier instead of 300 amp. Figure anything past 150 amps I'll probably just be using AC to avoid arc blow, I'll let you know if it burns up. ### ⭐⭐⭐⭐⭐ Easy to implement on vintage battery charger. *by on Reviewed in the United States November 5, 2024* The full wave 200A rectifier unit arrived less than 18 hours after ordering it and was in perfect condition. It was used to replace a failed full wave rectifier assembly in a 40+ year old, heavy duty, battery charger / jump starter. The original rectifier circuit had failed, but the rest of the unit was okay. My son installed it without any problems and is back in business. The heat sink is isolated from ground, so mounting it posed no tricky electrical problems. This is the second of this type of device that I have purchased through Amazon. The first was used in a wire welder. It still works great. Be sure to used crimp-on rings or spade luges when connecting it up as you are presumably using it for high current applications and want the best electrical contact possible. I would (and likely will) buy another one. ### ⭐⭐⭐⭐⭐ Easy and big improvement *by on Reviewed in the United States March 2, 2022* Followed a few YouTube videos to mod a cheap 110v welder. I used this TR and attached a heat sync to it. I kept it simple and didn’t add any capacitors and the welder is now great. I have used it on a few projects now, some were lengthy, and it never showed any signs of overheating. Much less splatter, arc seems very smooth and penetration improved. Rarely does “cheap and easy” work so well. ## Frequently Bought Together - Baomain High Power MDQ-200A 200A 1600V Single-Phase Full Wave Bridge Rectifier Module | AC to DC Diode Converter for PWM, Motor Excitation & Industrial Power Supplies - GENNEL G109 10gram Thermal Conductive Glue, Heatsink Silicone Glue, Thermal Plaster, Silicone Viscous Adhesive Compound for LED GPU MOSFET Printer Chipset IC High Performance - Aluminum Heat Sink Heatsink Module Cooler Cooling for Transistor Semiconductor Devices with 16 pcs Fins for Led Amplifier Transistor 3.93"(L) x 3.93"(W) x 0.7"(H) /100mm(L) x 100mm(W) x 18mm(H) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ae/products/225228363-baomain-mdq-200a-1600v-single-phase-diode-bridge-rectifier-full](https://www.desertcart.ae/products/225228363-baomain-mdq-200a-1600v-single-phase-diode-bridge-rectifier-full) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-06-16*
