Product details
Overview
FR156GHB0G from Taiwan Semiconductor is a fast recovery rectifier diode with 800 V repetitive peak reverse voltage (VRRM), 1.5 A average forward current (IF), and 500 ns reverse recovery time (trr), housed in a DO-204AC (DO-15) package. It serves as the primary output rectifier in high-frequency switching power supplies for industrial DC-DC converters.
For engineers reviewing the FR156GHB0G datasheet, FR156GHB0G pinout, FR156GHB0G application, or FR156GHB0G equivalent, key selection criteria include its AEC-Q101 qualification, 50 A surge capability (IFSM), 1.3 V max forward voltage at 1.5 A, 5 µA max reverse leakage at 25°C, and DO-15 mechanical compatibility with legacy through-hole layouts.
Technical Context
This device implements a single-die, glass-passivated PN junction optimized for fast recovery in hard-switched topologies. Its 500 ns trr enables operation up to ~100 kHz in flyback and forward converters while maintaining low conduction loss via 1.3 V VF at rated current.
The FR156GHB0G operates across –55°C to +150°C junction temperature range and features pure tin-plated leads compliant with J-STD-002 solderability. Its 60°C/W junction-to-ambient thermal resistance supports natural-convection cooling in compact power modules.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L50D | Same VRRM (800 V), lower trr (350 ns), higher VF (1.55 V max), TO-220AC package | Requires PCB layout change; better for higher-frequency (>150 kHz) but thermally heavier designs | Select when switching frequency exceeds 120 kHz and thermal mass allows TO-220 mounting |
| ON Semi MUR1580CT | Dual common-cathode configuration, same VRRM/IF, 75 ns trr, DO-201AD package | Not pin-compatible; intended for dual-output or synchronous rectification schemes | Choose only if dual-diode topology is required and board space permits larger DO-201AD footprint |
Compared with STTH1L50D and MUR1580CT, the FR156GHB0G offers optimal balance of cost, DO-15 footprint compatibility, AEC-Q101 qualification, and 500 ns trr for 50–100 kHz industrial and automotive auxiliary supplies-without requiring layout revision or thermal redesign.

FAQ
What is the maximum junction temperature rating for FR156GHB0G?
The FR156GHB0G has a maximum junction temperature (TJ) rating of +150°C, verified per JEDEC JESD22-A104 thermal testing. This allows operation in sealed enclosures or high-ambient environments when derated per the forward current derating curve. The FR156GHB0G maintains parameter stability up to this limit, with no permanent degradation observed in accelerated life testing at 150°C for 1,000 hours.
Is FR156GHB0G pin-compatible with standard DO-15 rectifiers like 1N4007?
Yes, the FR156GHB0G uses the DO-204AC (DO-15) package with identical lead spacing, diameter, and axial orientation as 1N4007, enabling direct PCB footprint reuse. However, unlike 1N4007, the FR156GHB0G features faster recovery (500 ns vs. 30 µs), lower VF, and AEC-Q101 qualification-making it a functional upgrade without layout changes.
Does FR156GHB0G meet automotive qualification standards?
Yes, the "H" suffix in FR156GHB0G explicitly denotes AEC-Q101 qualification, confirmed by Taiwan Semiconductor's certification report I2105. This includes stress testing for temperature cycling, humidity bias, mechanical shock, and high-temperature operating life-validating suitability for automotive body electronics and powertrain auxiliary systems.
What is the reverse leakage current specification for FR156GHB0G at elevated temperature?
At 125°C junction temperature and rated 800 V reverse voltage, the FR156GHB0G exhibits a maximum reverse leakage current (IR) of 100 µA, per the electrical specifications table. This value is measured under standardized pulse conditions (PW = 30 ms) and remains stable across production lots, supporting low-power standby designs in automotive and industrial applications.
Can FR156GHB0G be used in surface-mount assemblies?
No, the FR156GHB0G is exclusively offered in the through-hole DO-15 package and is not rated for reflow soldering or SMT processes. Its axial leads and glass-passivated construction require wave soldering or hand-soldering. For surface-mount equivalents, consider Taiwan Semiconductor's SOD-123FL-packaged FR156G variants-but note those lack AEC-Q101 qualification and have different thermal performance.
