What This Component Does
This device converts an AC (alternating current) input into a pulsating DC (direct current) output. It integrates four diodes internally in a bridge configuration, enabling full-wave rectification from a single component. The "07" in the part number designates this as the highest voltage variant in the TS25P0xG series (TS25P01G through TS25P07G span 50V up to 1000V), making it suited for higher-voltage AC input rectification stages compared to its lower-numbered siblings.

Important Usage Notes (for support/troubleshooting reference)
- This is a very high voltage-rated part: At 1000V VRRM, this is the top of its series — often chosen deliberately for extra safety margin in circuits with high-voltage AC input, voltage surges, or heavily inductive loads (motors, transformers), even when the nominal line voltage is much lower.
- Heatsinking still matters: Despite the high voltage rating, the 25A current rating still assumes proper heatsink mounting via the center hole. Insufficient heatsinking is a common cause of thermal-related failure even in high-voltage-rated parts like this.
- Inrush current is expected: A brief surge while charging input filter capacitors at power-up is normal and falls within the 350A surge rating, provided it's momentary rather than sustained.
- AC pins are non-polarized; DC pins are not: The two "~" terminals can be wired in either orientation, but "+" and "−" DC output pins must be connected correctly to protect downstream components.
- Don't substitute a lower-voltage variant: Since this part looks visually identical to lower-voltage siblings (TS25P01G–TS25P06G) apart from the printed marking, always double check the exact part number before using it as a replacement in a design that specifically calls for 1000V VRRM headroom.
Typical Applications
High-voltage switch-mode power supplies (SMPS), industrial AC-to-DC power conversion, motor drive rectification stages, and any circuit requiring extra reverse-voltage safety margin beyond standard 600V/800V-rated bridge rectifiers.
