Product details
Overview
HS2FH from Taiwan Semiconductor is a 300 V, 2 A surface-mount fast recovery rectifier diode in DO-214AA (SMB) package, featuring 50 ns reverse recovery time, 1.0 V forward voltage at 2 A, and 5 µA reverse leakage at 25°C. It serves as a freewheeling or snubber diode in automotive DC-DC converters and LED lighting power stages.
For engineers reviewing the HS2FH datasheet, HS2FH pinout, HS2FH application, or HS2FH equivalent, key selection criteria include repetitive peak reverse voltage (VRRM = 300 V), thermal resistance (RθJA = 80 °C/W), junction temperature range (–55 to +150 °C), and AEC-Q101 qualification for automotive reliability.
Technical Context
The HS2FH is a single-die, glass-passivated silicon PN junction rectifier optimized for high-efficiency switching operation. Its 50 ns trr and low VF enable reduced conduction and switching losses in medium-voltage, medium-current DC-DC topologies.
Designed for automated SMT placement, it meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements. Polarity is marked by a cathode band; terminals are matte tin-plated per J-STD-002 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| VRRM | 300 V - supports input rails up to 300 V DC in buck, flyback, or snubber circuits |
| IF | 2 A continuous - rated for sustained output current in automotive lighting drivers |
| trr | 50 ns - enables efficient operation at switching frequencies up to ~200 kHz |
| VF @ 2 A | 1.0 V max - limits conduction loss to ≤2.0 W at full load, easing thermal design |

| IR @ 25°C | 5 µA max - ensures low standby leakage in battery-coupled systems |
| TJ Range | –55 to +150 °C - qualified for under-hood automotive environments |

Applications
| Automotive DC-DC Converters | LED Headlamp Drivers |
|---|---|
Use Scenario: Step-down conversion from 12 V/24 V battery to regulated 5–12 V for control modules. IC Role / Device Role / Timing Role: Freewheeling diode in synchronous or asynchronous buck converter secondary path. Use Value: 50 ns trr minimizes reverse recovery charge loss, improving efficiency by ~1.2% over 100 ns alternatives at 100 kHz. | Use Scenario: Constant-current driver for high-brightness automotive headlamps with PWM dimming. IC Role / Device Role / Timing Role: Snubber diode across MOSFET switch to clamp inductive voltage spikes.

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-2EY30-M3/57T | VRRM = 300 V, IF = 2 A, trr = 50 ns, same DO-214AA package | Qualified to AEC-Q101 but with different test report scope (e.g., no HTRB at 150°C) | Drop-in replacement where full TSC AEC-Q101 test report coverage is not required |
| ON Semiconductor MUR230 | VRRM = 300 V, IF = 2 A, trr = 50 ns, DO-214AC (SMA) package - smaller footprint, higher RθJA = 100 °C/W | Limited thermal margin at 2 A continuous; unsuitable for sealed enclosures above 60°C ambient | Use only with derated current (≤1.5 A) or enhanced PCB copper in space-constrained layouts |
Compared with VS-2EY30-M3/57T and MUR230, the HS2FH provides identical electrical ratings and AEC-Q101 compliance with verified HTRB performance at 150°C, making it preferred for high-reliability automotive power stages where thermal stress and long-term bias stability are critical.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) rating for HS2FH?
The HS2FH has a VRRM rating of 300 V, meaning it can reliably block reverse voltages up to 300 V in repetitive applications such as DC-DC converter freewheeling paths. This value is confirmed in the Absolute Maximum Ratings table of the official HS2AH–HS2MH datasheet (Version A2102), and is specific to the HS2FH variant-not extrapolated from adjacent part numbers.
Is HS2FH qualified for automotive applications?
Yes, HS2FH is explicitly AEC-Q101 qualified per the manufacturer's documentation. This includes stress testing for temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge-validating its suitability for under-hood and lighting modules. The qualification applies directly to the HS2FH device, not just the HS2xH family generically.
What is the forward voltage drop of HS2FH at 2 A and 25°C?
The forward voltage (VF) of HS2FH is specified as a maximum of 1.0 V at IF = 2 A and TJ = 25°C, per the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and reflects typical conduction loss behavior in switching power supplies operating near room temperature.
Does HS2FH have a defined reverse recovery time (trr)?
Yes, HS2FH has a 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 explicitly listed in the Electrical Specifications table for HS2FH and distinguishes it from slower rectifiers like general-purpose 1N400x series, enabling higher-frequency SMPS designs.
What package type does HS2FH use, and is it RoHS compliant?
HS2FH uses the DO-214AA (SMB) surface-mount package with matte tin-plated leads. It is fully RoHS compliant and halogen-free per IEC 61249-2-21, as stated in the FEATURES section of the official datasheet. The molding compound also meets UL 94V-0 flammability requirements.
