Product details
Overview
HS1MFL from Taiwan Semiconductor is a 1 A, 1000 V repetitive peak reverse voltage (VRRM) surface-mount fast recovery rectifier in SOD-123FL package, featuring 1.36 V typical forward voltage at 1.0 A and 25°C, 75 ns reverse recovery time, and 6 pF junction capacitance - deployed in high-efficiency DC-DC converters and switching inverters.
For engineers reviewing the HS1MFL datasheet, HS1MFL pinout, HS1MFL application, or HS1MFL equivalent, key selection criteria include its 1000 V VRRM, low-profile SOD-123FL footprint, thermal resistance of 17 °C/W (junction-to-lead), 150 °C max junction temperature, and suitability for freewheeling and snubber circuits in industrial power supplies.
Technical Context
The HS1MFL is a single-die, glass-passivated silicon PN junction rectifier optimized for fast switching and low conduction loss in high-voltage SMPS topologies. Its 75 ns reverse recovery time and 6 pF junction capacitance support operation up to several hundred kHz with minimal switching loss.
Designed for surface-mount assembly on standard PCBs with 5 mm × 5 mm copper pads, it delivers 1 A average forward current with derating above 75°C ambient and withstands 30 A non-repetitive surge current per 8.3 ms half-sine waveform.
Key Specifications

Applications
| AC-DC Adapter Output Rectification | Industrial DC-DC Converter Freewheeling |
|---|---|
Use Scenario: Secondary-side rectification in 12–24 V, 10–25 W offline flyback adapters with universal AC input. IC Role / Device Role / Timing Role: Unidirectional current steering and energy transfer during transformer reset phase. Use Value: 1000 V VRRM provides margin against reflected voltage spikes; 1.36 V VF limits conduction loss to <1.4 W at full load. | Use Scenario: Freewheeling path in 48 V input, 12 V output synchronous buck converter for PLC I/O modules. IC Role / Device Role / Timing Role: Provides safe current recirculation when high-side MOSFET turns off. Use Value: 75 ns trr minimizes reverse recovery charge (Qrr), reducing cross-conduction loss and EMI generation. |
| Switch-Mode Inverter Snubber Diode | High-Voltage Battery Management System Clamp |
Use Scenario: RCD snubber network across IGBTs in 3-phase 400 V motor drives operating at 8–16 kHz. IC Role / Device Role / Timing Role: Clamps voltage overshoot during IGBT turn-off by absorbing inductive energy. Use Value: 1000 V VRRM withstands transient spikes exceeding 700 V; 30 A IFSM handles short-duration snubber surges. | Use Scenario: Overvoltage clamp in 72–96 V battery string monitoring circuitry for EV auxiliary systems. IC Role / Device Role / Timing Role: Blocks reverse leakage while clamping transients above rated bus voltage. Use Value: 5 µA max reverse leakage at 25°C ensures negligible standby current drain; 150 µA at 125°C remains within BMS leakage budgets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06 | 600 V VRRM, 70 ns trr, TO-277 package (larger footprint, higher RθJA) | Not suitable for 800–1000 V bus applications; requires larger PCB area | Select only if system VRRM requirement ≤600 V and thermal budget permits higher RθJA |
| MBR1100 | 1000 V VRRM, Schottky structure, but 1.7 V VF @ 1 A and 125°C; not RoHS/halogen-free certified | Higher conduction loss and unverified environmental compliance limits use in regulated markets | Prefer HS1MFL where low VF stability over temperature and regulatory compliance are mandatory |
Compared with STTH1R06 and MBR1100, the HS1MFL uniquely balances 1000 V rating, 75 ns recovery, SOD-123FL space efficiency, and full RoHS/halogen-free compliance - making it optimal for compact, thermally constrained, and globally certified industrial power designs.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) rating for HS1MFL?
The HS1MFL has a maximum repetitive peak reverse voltage (VRRM) rating of 1000 V, confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet Version B2103. This rating applies under standard test conditions (TA = 25°C) and defines the highest reverse voltage the device can block repeatedly without breakdown. It is the highest rating in the HS1xFL series, distinguishing HS1MFL from lower-voltage variants like HS1GFL (800 V) and HS1JFL (600 V).
Does HS1MFL have a specified reverse recovery time (trr) and how is it measured?
Yes, the HS1MFL has a specified reverse recovery time (trr) of 75 ns maximum, measured under conditions of IF = 0.5 A, IR = 1.0 A, and IRR = 0.25 A, per the Electrical Specifications table in the Taiwan Semiconductor datasheet. This value reflects the time required for the device to transition from forward conduction to reverse blocking state and is critical for minimizing switching losses in high-frequency converters.
What is the forward voltage (VF) of HS1MFL at 1.0 A and 25°C?
The forward voltage (VF) of HS1MFL is 1.36 V typical at 1.0 A and 25°C, with a maximum of 1.70 V under the same conditions. This value is explicitly listed in the Electrical Specifications table for the HS1MFL variant and is higher than lower-voltage members of the family (e.g., HS1AFL: 0.89 V), reflecting the trade-off between blocking voltage and conduction loss in silicon rectifiers.
Is HS1MFL compliant with RoHS and halogen-free standards?
Yes, HS1MFL is RoHS compliant and halogen-free according to IEC 61249-2-21, as stated in the FEATURES section of the Taiwan Semiconductor datasheet. The device uses matte tin-plated leads and a UL 94V-0 molding compound, satisfying environmental requirements for industrial and consumer electronics sold in EU, US, and Asia-Pacific markets.
What package type does HS1MFL use and what are its mechanical identifiers?
HS1MFL uses the SOD-123FL package, a low-profile surface-mount outline with cathode polarity indicated by a visible band. Mechanical data confirm its weight is approximately 0.019 g, lead finish is matte tin per J-STD-002, and it meets JESD 201 Class 1A whisker resistance. The package is moisture sensitivity level 1 (J-STD-020), allowing unlimited floor life before reflow.
