Product details
Overview
HS5FH from Taiwan Semiconductor is a 300V, 5A surface-mount high-efficiency fast recovery rectifier in DO-214AB (SMC) package, featuring 50 ns reverse recovery time, 1.00 V forward voltage at 5A/25°C, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the HS5FH datasheet, HS5FH pinout, HS5FH application, or HS5FH equivalent, key selection criteria include repetitive peak reverse voltage (300 V), surge current capability (150 A), junction-to-ambient thermal resistance (60 °C/W), low-profile SMC packaging, and suitability for DC-DC converters and freewheeling circuits requiring robust transient handling.
Technical Context
This device is a single-die, glass-passivated silicon junction rectifier optimized for fast switching with controlled reverse recovery behavior. Its 50 ns trr and 80 pF junction capacitance at 1 MHz/4 V support high-frequency operation in snubber and flyback topologies.
Rated for continuous forward current of 5 A and peak surge current of 150 A (8.3 ms half-sine), it operates across -55°C to +150°C junction temperature range and meets J-STD-020 moisture sensitivity level 1, enabling compatibility with standard reflow processes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 300 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in flyback or snubber circuits |

| CJ @ 1MHz/4V | 80 pF - Junction capacitance; influences high-frequency noise coupling and EMI filter design |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-5EWH03-M3 | Same VRRM (300 V), IF (5 A), but trr = 35 ns; VF = 0.92 V @ 5A; DO-214AB package | Higher switching speed suits >500 kHz resonant converters; lower VF reduces conduction loss further | Preferred where ultra-low trr and VF are critical; verify layout thermal relief matches TSC's 60 °C/W spec |
| ON Semiconductor MUR530G | VRRM = 300 V, IF = 5 A, trr = 50 ns, VF = 1.25 V @ 5A; TO-220AC package (not SMD) | Through-hole mounting requires manual assembly or wave solder; higher RθJA (~40 °C/W with heatsink) | Only suitable if board redesign accommodates through-hole footprint and thermal management differs |
Compared with VS-5EWH03-M3, HS5FH offers slightly higher VF but identical trr and superior AEC-Q101 qualification; versus MUR530G, HS5FH enables automated SMT assembly and eliminates through-hole rework, though thermal interface design must account for its 60 °C/W RθJA without external heatsink.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) rating for HS5FH?
The HS5FH has a VRRM rating of 300 V, meaning it can reliably block up to 300 volts of reverse voltage in repetitive applications such as DC-DC converter outputs or snubber networks. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet Version A2102 and is specific to the HS5FH variant within the HS5xH family.
Is HS5FH qualified for automotive applications?
Yes, HS5FH is AEC-Q101 qualified, as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. This qualification covers stress tests including temperature cycling, high-temperature operating life, and mechanical shock, making HS5FH suitable for under-hood automotive systems like LED drivers and engine control modules.
What is the forward voltage drop of HS5FH at rated current?
HS5FH exhibits a maximum forward voltage (VF) of 1.00 V at 5 A and 25°C, per the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and represents typical conduction loss under nominal load, directly impacting thermal design and system efficiency in high-current rectification paths.
Does HS5FH have a specified reverse recovery time (trr)?
Yes, HS5FH has a maximum reverse recovery time (trr) of 50 ns, tested at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter is documented in the Electrical Specifications table and confirms its classification as a fast recovery rectifier suitable for switching frequencies up to several hundred kHz in DC-DC and snubber applications.
What package type does HS5FH use, and is it compatible with automated assembly?
HS5FH uses the DO-214AB (SMC) surface-mount package, which is explicitly noted as ideal for automated placement in the FEATURES section. Its matte tin-plated leads comply with J-STD-002 solderability standards, and its moisture sensitivity level 1 rating per J-STD-020 allows direct use in reflow processes without baking or dry-pack handling.
