Product details
Overview
T25JA05G-K from Taiwan Semiconductor is a 25A, 600V standard quad bridge rectifier in TS-6PL package, featuring glass-passivated junctions, 312A peak surge current capability, and UL Recognized (E-326243) construction; it delivers reliable AC-to-DC conversion in compact PCB-mounted power supplies.
For engineers reviewing the T25JA05G-K datasheet, T25JA05G-K pinout, T25JA05G-K application, or T25JA05G-K equivalent, key selection criteria include its 600V repetitive peak reverse voltage, 1.15V max forward voltage at 25A/25°C, 4°C/W junction-to-lead thermal resistance, and TS-6PL mechanical compatibility with high-density SMPS layouts.
Technical Context
The T25JA05G-K integrates four silicon diodes in a single-phase full-wave bridge configuration, optimized for continuous conduction mode operation in offline AC-DC converters. Its glass-passivated junction ensures stable reverse leakage (<5µA @ 25°C, <380µA @ 125°C) and robust surge handling (900A @ 1ms).
Thermal performance is defined by RθJL = 4°C/W and RθJC = 5°C/W when mounted on a 4"×6"×0.25" aluminum heatsink, enabling sustained 25A average forward current up to 150°C junction temperature with appropriate board-level copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF (Avg) | 25 A - Sustained DC output current capability in SMPS primary-side rectification |
| VRRM | 600 V - Maximum repetitive reverse voltage per diode; defines input AC line voltage derating margin (e.g., 230VAC RMS → 325V peak) |
| IFSM (8.3ms) | 312 A - Short-duration surge rating; withstands inrush currents during cold-start of adapters and lighting drivers |
| VF (max @ 25A, 25°C) | 1.15 V - Worst-case forward drop per diode; determines conduction loss (≈2.3W total bridge loss at 25A) |
| RθJL | 4 °C/W - Junction-to-lead thermal resistance; enables direct thermal coupling to PCB copper pour without external heatsink in low-power designs |
| IR (max @ 125°C) | 380 µA - Maximum reverse leakage per diode at elevated temperature; critical for standby power compliance in energy-efficient lighting |
| CJ (per diode) | 92.3 pF @ 1MHz, 4V - Junction capacitance affecting EMI filter design and high-frequency switching noise in PFC stages |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bridge rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| GBU25J (ON Semiconductor) | Same 25A/600V rating, GBU package (larger than TS-6PL), RθJA = 20°C/W vs. 14°C/W | Requires larger PCB area and heatsinking; less suitable for ultra-compact adapters | Select when legacy GBU footprint compatibility is required and thermal headroom exists |
| GBU25K (Vishay) | 25A/800V rating, same GBU package; higher VRRM but 1.25V VF max @ 25A | Better voltage margin for 305VAC regions; higher conduction loss reduces efficiency in low-voltage-output designs | Select for universal-input designs targeting 305VAC peak or where 800V rating simplifies BOM consolidation |
Compared with GBU25J and GBU25K, the T25JA05G-K offers superior thermal performance (RθJL = 4°C/W) and smaller TS-6PL footprint, making it optimal for space-constrained, high-efficiency SMPS where 600V rating suffices for 230VAC nominal systems.

FAQ
What is the maximum junction temperature rating for the T25JA05G-K?
The T25JA05G-K has a maximum junction temperature (TJ) of +150°C, verified per absolute maximum ratings table. This rating allows continuous operation at full 25A forward current when thermal design maintains junction temperature ≤150°C-achievable via adequate PCB copper area or heatsink mounting per the specified RθJL = 4°C/W and RθJC = 5°C/W values. The T25JA05G-K must not be operated beyond this limit to ensure reliability and lifetime compliance.
Does the T25JA05G-K meet UL safety standards?
Yes, the T25JA05G-K is UL Recognized under File # E-326243, confirming compliance with UL 60747-4 for semiconductor devices. This recognition covers construction, flammability (UL 94V-0 molding compound), and electrical safety parameters including VRRM, IFSM, and isolation. The T25JA05G-K may be used in end products seeking UL/CSA certification without requiring additional component-level safety testing.
What is the forward voltage drop of the T25JA05G-K at rated current?
The T25JA05G-K exhibits a typical forward voltage of 1.08V and a maximum of 1.15V per diode at 25A and 25°C, as specified in the electrical characteristics table. At 125°C junction temperature, the max VF drops to 1.09V due to negative temperature coefficient behavior. Total bridge conduction loss is therefore ≤2.3W at room temperature and ≤2.18W at elevated temperature, directly impacting SMPS efficiency calculations.
Is the T25JA05G-K compatible with lead-free reflow soldering processes?
Yes, the T25JA05G-K features matte tin-plated leads qualified to J-STD-002 for solderability and is rated for lead-free reflow profiles (peak temperature ≤260°C). Its TS-6PL package withstands standard JEDEC J-STD-020 moisture sensitivity level (MSL) requirements, and the device is halogen-free per IEC 61249-2-21-ensuring compatibility with RoHS-compliant manufacturing lines using Pb-free solder paste.
How does the T25JA05G-K differ from the T25JA06G-K and T25JA07G-K?
The T25JA05G-K, T25JA06G-K, and T25JA07G-K share identical package (TS-6PL), current rating (25A), thermal specs, and features-but differ only in repetitive peak reverse voltage: 600V (T25JA05G-K), 800V (T25JA06G-K), and 1000V (T25JA07G-K). Marking codes are T25JA05G, T25JA06G, and T25JA07G respectively. All three are drop-in replacements in layout; only VRRM selection changes based on input voltage range and safety margin requirements.
