Product details
Overview
T25JA07G-K from Taiwan Semiconductor is a 25A, 1000V standard quad bridge rectifier in TS-6PL package, featuring glass-passivated junctions, 312A peak surge current capability, and UL Recognized File # E-326243 - used in high-reliability AC/DC front-end stages of industrial SMPS.
For engineers reviewing the T25JA07G-K datasheet, T25JA07G-K pinout, T25JA07G-K application, or T25JA07G-K equivalent, key selection criteria include VRRM = 1000V, IF = 25A, IFSM = 312A (8.3ms), RθJL = 4°C/W, and TS-6PL mechanical compatibility with PCB-mount heat sinking.
Technical Context
The T25JA07G-K integrates four silicon diodes in a single-phase bridge configuration with common-cathode/common-anode topology, rated for repetitive reverse voltage up to 1000V and continuous forward current of 25A at TC = 75°C. Its glass-passivated junction ensures stable leakage performance across -55°C to +150°C junction temperature range.
Thermal design relies on low junction-to-lead resistance (RθJL = 4°C/W) when mounted on a 4" × 6" × 0.25" aluminum heatsink, enabling sustained operation under high ambient conditions without forced airflow. Reverse current remains ≤380 µA at TJ = 125°C and VR = 700V RMS.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - maximum non-repetitive reverse voltage the device blocks without breakdown |
| IF | 25 A - continuous average forward current at TC = 75°C, defining thermal derating baseline |
| IFSM (8.3ms) | 312 A - peak surge current handling for short-line transients in AC input stages |
| RθJL | 4 °C/W - enables direct thermal path to PCB copper or heatsink, critical for passive cooling |
| VF @ 25A, 25°C | 1.08–1.15 V - forward voltage drop per diode, directly impacting conduction loss and efficiency |
| IR @ 125°C | ≤380 µA - low reverse leakage ensures minimal standby power loss in high-temp environments |
| Package | TS-6PL - surface-mountable 6-pin leaded package with UL 94V-0 molding compound |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-25B10 | VRRM = 1000V, IF = 25A, but uses TO-220AC package with higher RθJA (30°C/W); no UL recognition | Requires external heatsink mounting; not suitable for UL-certified end products without additional system validation | Select when mechanical fit prioritizes TO-220 footprint and UL recognition is not required |
| ON Semiconductor GBPC2510 | VRRM = 1000V, IF = 25A, GBPC package (larger than TS-6PL); RθJL = 5.5°C/W; UL Recognized File # E171272 | Higher thermal resistance and larger board area needed; compatible with legacy through-hole layouts | Select when existing PCB design uses GBPC footprint or requires higher creepage/clearance margins |
Compared with VS-25B10 and GBPC2510, the T25JA07G-K offers superior thermal performance (RθJL = 4°C/W), smaller TS-6PL footprint, and UL recognition - making it optimal for space-constrained, certified industrial power supplies where thermal management and regulatory compliance are critical.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) rating for the T25JA07G-K?
The T25JA07G-K has a VRRM rating of 1000 V, confirmed in the Absolute Maximum Ratings table for this exact part number. This value is distinct from lower-voltage variants (e.g., T25JA05G-K = 600 V, T25JA06G-K = 800 V) and defines the highest transient reverse voltage the device can block repeatedly without breakdown. The 1000 V rating makes T25JA07G-K suitable for 400 VAC+ input applications and high-surge industrial environments.
Does the T25JA07G-K have UL recognition, and what is the file number?
Yes, the T25JA07G-K is UL Recognized under File # E-326243, as explicitly stated in the FEATURES section of the official datasheet. This recognition applies to the entire T25JA05G-K through T25JA07G-K family and validates compliance with UL 60747-4 for semiconductor devices. It supports faster end-product safety certification without requiring additional component-level testing.
What is the forward voltage (VF) of the T25JA07G-K at full rated current and room temperature?
At IF = 25.0 A and TJ = 25°C, the T25JA07G-K exhibits a typical forward voltage of 1.08 V and a maximum of 1.15 V per diode, per the Electrical Specifications table. This VF value directly determines conduction losses in the bridge - for example, at 25 A, total power dissipation across all four diodes is approximately 10.8 W (4 × 1.08 V × 25 A × 0.5 duty cycle).
What package type does the T25JA07G-K use, and what are its key mechanical attributes?
The T25JA07G-K uses the TS-6PL package: a 6-pin, surface-mountable, molded plastic case with UL 94V-0 flammability rating. Key mechanical attributes include matte tin-plated leads compliant with J-STD-002, JESD 201 Class 1 whisker resistance, 0.78 N·m maximum mounting torque, and 4.40 g unit weight. Polarity is marked on the top surface per the Marking Diagram.
How does the thermal performance of the T25JA07G-K compare to standard bridge rectifiers?
The T25JA07G-K achieves a junction-to-lead thermal resistance (RθJL) of 4°C/W when mounted on a 4" × 6" × 0.25" aluminum heatsink - significantly lower than typical GBPC or TO-220-based bridges (often >5.5°C/W). This enables higher power density and reduced heatsink size. Its RθJA of 14°C/W also reflects optimized thermal path design, supporting operation up to 150°C junction temperature without derating.
