Product details
Overview
FR156GH from Taiwan Semiconductor is a 1.5A, 800V fast recovery rectifier diode in DO-204AC (DO-15) package, featuring 500 ns reverse recovery time, 1.3 V max forward voltage at 1.5 A, and AEC-Q101 qualification for automotive-grade reliability. It serves as a primary output rectifier in high-frequency switching power supplies.
For engineers reviewing the FR156GH datasheet, FR156GH pinout, FR156GH application, or FR156GH equivalent, key selection criteria include its 800 V repetitive peak reverse voltage, 50 A surge capability, glass-passivated junction, RoHS/halogen-free compliance, and thermal resistance of 60 °C/W - all critical for DC-DC converter and SMPS design validation.
Technical Context
This single-die fast recovery rectifier uses a planar epitaxial structure with glass passivation to achieve stable reverse blocking up to 800 V and low leakage (<5 µA at 25°C). Its 500 ns trr enables efficient operation in 50–500 kHz switching topologies without excessive switching loss.
The device operates across –55°C to +150°C junction temperature range and delivers 1.5 A average forward current with derating above 75°C ambient. Its DO-204AC package supports automated assembly and meets UL 94V-0 flammability and JESD201 Class 2 whisker resistance requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L50S | 1.5 A, 500 V, 150 ns trr, TO-220AC package | Limited to ≤500 V systems; lower trr but larger footprint and higher thermal mass | Select when faster recovery is prioritized over voltage rating and board space is not constrained |
| ON Semi MUR1580 | 1.5 A, 800 V, 75 ns trr, DO-15 package, no AEC-Q101 | Superior speed but lacks automotive qualification and halogen-free certification | Choose for cost-sensitive industrial SMPS where AEC-Q101 and environmental compliance are not required |
Compared with STTH1L50S and MUR1580, FR156GH uniquely balances 800 V rating, AEC-Q101 qualification, halogen-free construction, and DO-15 compatibility-making it the only option qualified for automotive under-hood DC-DC converters requiring all four attributes.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of FR156GH?
The FR156GH has a VRRM rating of 800 V, confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version I2105). This value defines the highest reverse voltage the device can block repeatedly without breakdown and is strictly validated for FR156GH - not extrapolated from adjacent variants like FR155G (600 V) or FR157G (1000 V).
Is FR156GH qualified to AEC-Q101 standards?
Yes, FR156GH is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code and confirmed in the FEATURES section of the datasheet. This qualification covers stress testing for temperature cycling, humidity bias, and mechanical shock - making FR156GH suitable for automotive power supply applications where reliability under harsh conditions is mandatory.
What is the reverse recovery time (trr) of FR156GH and how is it measured?
The FR156GH has a reverse recovery time of 500 ns, measured under specified conditions: IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A, per the Electrical Specifications table. This value is confirmed for FR156GH and FR157G only - other variants in the FR15xG family have lower trr (e.g., FR155G = 250 ns), so the 500 ns rating must not be assumed for non-H-suffix or non-6/7 variants.
Does FR156GH have halogen-free and RoHS-compliant construction?
Yes, FR156GH meets both RoHS Directive 2011/65/EU and halogen-free requirements per IEC 61249-2-21, as stated in the FEATURES section. The molding compound is UL 94V-0 rated, and the leads are pure tin-plated - all verified for FR156GH in the official documentation and not generalized from the broader FR15xG family.
What package type does FR156GH use and what are its mechanical identifiers?
FR156GH uses the DO-204AC (DO-15) axial-leaded package, confirmed in the MECHANICAL DATA and ORDERING INFORMATION sections. Key identifiers include cathode band marking, pure tin-plated leads compliant with J-STD-002, 0.400 g typical weight, and UL 94V-0 flammability rating - all specific to FR156GH's production release.
