Product details
Overview
HS2MFSH from Taiwan Semiconductor is a 1000 V, 2 A surface-mount fast recovery rectifier in SOD-128 package, featuring 1.48 V max forward voltage at 2 A/25°C, 75 ns reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability. It serves as a high-efficiency freewheeling or snubber diode in DC/DC converters operating under high-voltage transient conditions.
For engineers reviewing the HS2MFSH datasheet, HS2MFSH pinout, HS2MFSH application, or HS2MFSH equivalent, key selection criteria include its 1000 V repetitive peak reverse voltage, low-profile SOD-128 thermal performance (RθJL = 17°C/W), junction temperature rating up to +150°C, and verified suitability for automotive power conversion systems requiring robust surge handling and low leakage.
Technical Context
The HS2MFSH uses a glass-passivated silicon die optimized for fast switching and low conduction loss at high blocking voltages. Its 75 ns reverse recovery time and 12 pF junction capacitance at 1 MHz/4 V enable efficient operation in high-frequency DC/DC topologies.
Thermally, it delivers RθJL = 17°C/W and RθJA = 53°C/W on a 5 mm × 5 mm Cu pad, supporting sustained 2 A average forward current with junction temperatures maintained below 150°C under typical PCB mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| IF | 2 A continuous - rated for stable conduction in compact power supplies |
| VF (max) | 1.70 V at 2 A/25°C - limits conduction loss to ≤3.4 W per device |
| trr | 75 ns - enables operation up to ~2 MHz switching frequencies with minimal switching loss |
| CJ | 12 pF at 1 MHz/4 V - reduces capacitive loading in high-speed gate-drive or snubber circuits |
| IR (max) | 1 µA at 25°C, 80 µA at 125°C - ensures low leakage in high-impedance hold-up or sensing paths |
| TJ max | +150°C - allows deployment in under-hood automotive environments without forced cooling |

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-2EY100 | Same VRRM (1000 V), but higher VF (1.8 V typ @ 2 A), slower trr (100 ns), SOD-128 package | Higher conduction loss and reduced switching efficiency in >500 kHz designs | Prefer HS2MFSH where low VF and fast trr are critical for thermal management |
| ON Semiconductor MUR2100E | Same VRRM and IF, but TO-220AC package, higher RθJA (65°C/W), no AEC-Q101 | Requires heatsink; unsuitable for automotive or space-constrained PCBs | Choose HS2MFSH for surface-mount integration, automotive compliance, and superior thermal performance on PCB |
Compared with VS-2EY100 and MUR2100E, the HS2MFSH offers the lowest combined conduction–switching loss in SOD-128 form factor, AEC-Q101 validation for automotive use, and best-in-class thermal resistance for passive-cooled designs.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of the HS2MFSH?
The HS2MFSH has a VRRM of 1000 V, confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version B2103). This rating applies across the full operating temperature range and defines the highest reverse voltage the device can block repeatedly without breakdown. The "M" in HS2MFSH explicitly denotes the 1000 V variant within the HS2xFSH series.
Is the HS2MFSH suitable for automotive applications?
Yes, the HS2MFSH is AEC-Q101 qualified per the manufacturer's documentation, making it suitable for automotive power electronics including DC/DC converters, body control modules, and ADAS power supplies. Its glass-passivated junction, 150°C junction rating, and moisture sensitivity level 1 ensure reliability in under-hood thermal and humidity environments.
What is the forward voltage (VF) of the HS2MFSH at 2 A and 25°C?
The HS2MFSH exhibits a maximum forward voltage of 1.70 V at 2 A and 25°C, with a typical value of 1.48 V under the same conditions. These values are specified in the Electrical Specifications table for the HS2KFSH and HS2MFSH variants and reflect measured performance under pulsed test conditions (PW = 0.3 ms).
Does the HS2MFSH have a defined reverse recovery time (trr)?
Yes, the HS2MFSH has a maximum reverse recovery time of 75 ns, tested at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter is explicitly grouped with HS2JFSH, HS2KFSH, and HS2MFSH in the datasheet's Electrical Specifications section and confirms its classification as a fast recovery rectifier.
What package type does the HS2MFSH use, and what are its key mechanical features?
The HS2MFSH uses the SOD-128 surface-mount package, characterized by a low profile (≤1.1 mm height), matte tin-plated leads compliant with J-STD-002, UL 94V-0 molding compound, and polarity indicated by a cathode band. Its mechanical data sheet confirms weight of approximately 0.028 g and compliance with JESD201 Class 2 whisker testing.
