Product details
Overview
HS1MF-T from Taiwan Semiconductor is a 1000 V, 1 A surface-mount high-efficiency fast recovery rectifier in SMAF package, featuring 75 ns reverse recovery time, 1.23 V typical forward voltage at 1.0 A/25°C, and 8 pF junction capacitance - deployed in DC-DC converters and switching inverters requiring high-voltage blocking and low-loss conduction.
For engineers reviewing the HS1MF-T datasheet, HS1MF-T pinout, HS1MF-T application, or HS1MF-T equivalent, key selection criteria include peak reverse voltage (1000 V), thermal resistance (RθJL = 15 °C/W), reverse leakage (≤125 µA at 125°C), and compatibility with automated SMT placement on standard PCB pads.
Technical Context
The HS1MF-T employs a single-die, glass-passivated PN junction optimized for fast recovery (trr ≤ 75 ns) and low leakage across -55°C to +150°C junction temperature range. Its 1000 V VRRM rating enables use in high-input-voltage SMPS front-ends and freewheeling paths where voltage transients exceed 700 V RMS.
Thermal design is supported by RθJL = 15 °C/W and RθJA = 89 °C/W (on 5 mm × 5 mm Cu pad), while its SMAF package meets UL 94V-0 and JESD201 Class 1 whisker requirements - confirming suitability for industrial-grade reflow and long-term reliability under thermal cycling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - supports input stages in 800 V AC-line or 600 V DC bus systems without derating |
| IF | 1 A continuous - rated for sustained conduction in compact power supplies with minimal heatsinking |
| trr | 75 ns max - reduces switching losses in 100–500 kHz converters versus standard rectifiers |
| VF | 1.23 V typ @ 1.0 A, 25°C - balances conduction loss and thermal rise in space-constrained layouts |
| IR | ≤125 µA @ 1000 V, 125°C - ensures stable blocking in high-temperature environments |
| CJ | 8 pF @ 1 MHz, 4 V - minimizes capacitive coupling noise in high-frequency gate-drive or sensing circuits |
| RθJL | 15 °C/W - enables direct thermal transfer to PCB copper, simplifying thermal management |
Pinout & Package

Applications
| DC-DC Converter Primary Side | Switching Inverter Freewheeling |
|---|---|
Use Scenario: High-voltage input stage of isolated flyback or forward converter operating from 300–800 V DC bus. IC Role / Device Role / Timing Role: Output rectifier handling repetitive 1000 V reverse stress and 1 A average forward current. Use Value: 1000 V VRRM eliminates need for series-connected diodes; 75 ns trr limits switching loss during MOSFET turn-on transitions. | Use Scenario: Freewheeling path across inductive loads in motor drive inverters or UPS output stages. IC Role / Device Role / Timing Role: Unidirectional current path that clamps inductive kickback and recirculates stored energy. Use Value: Low 8 pF CJ minimizes capacitive feedthrough into gate drivers; 15 °C/W RθJL sustains 1 A conduction without external heatsink. |
| AC-DC Adapter Secondary Rectification | Industrial Power Supply Snubber Network |
Use Scenario: Secondary-side rectification in universal-input offline adapters delivering up to 12 W at 12–24 V. IC Role / Device Role / Timing Role: High-efficiency output rectifier replacing Schottky diodes where >100°C ambient operation is required. Use Value: 150°C TJMAX and ≤125 µA IR at 125°C ensure stable performance where Schottkys exhibit thermal runaway. | Use Scenario: Voltage-clamping element in RCD snubber networks across high-voltage MOSFETs or IGBTs. IC Role / Device Role / Timing Role: Fast-recovery clamp diode absorbing turn-off energy spikes in 50–200 kHz switching nodes. Use Value: 75 ns trr ensures rapid recombination after transient absorption, preventing delayed conduction and secondary voltage overshoot. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06S | 600 V VRRM, 1.05 V VF @ 1 A, 50 ns trr, DO-214AA package | Limited to ≤600 V systems; faster recovery but lower voltage margin | Select when system VRRM requirement is ≤600 V and lowest possible trr is critical |
| ES1J-M3/5AT | 600 V VRRM, 1.7 V VF max @ 1 A, 35 ns trr, SMA package | Higher forward drop increases conduction loss; not suitable for 1000 V designs | Prefer where ultra-fast recovery dominates over voltage rating and thermal efficiency |
Compared with STTH1L06S and ES1J-M3/5AT, the HS1MF-T uniquely delivers 1000 V blocking capability with balanced 75 ns trr and 1.23 V forward drop - making it the only option among the three qualified for 800 V DC bus rectification without series stacking or derating.

FAQ
What is the maximum repetitive peak reverse voltage rating for HS1MF-T?
The HS1MF-T has a maximum repetitive peak reverse voltage (VRRM) of 1000 V, verified per TSC datasheet Version B2103. This rating allows the HS1MF-T to operate reliably in high-input-voltage power supplies, including those derived from 3-phase rectified AC or boosted DC bus architectures where transient voltages may approach 900 V. The 1000 V margin ensures design headroom against voltage spikes and line surges.
Does HS1MF-T support automated SMT assembly?
Yes, the HS1MF-T supports automated surface-mount assembly per J-STD-002 standards. Its SMAF package features matte tin-plated leads, moisture sensitivity level (MSL) 1, and is qualified for standard 260°C lead-free reflow profiles. The device's polarity marking (cathode band) and consistent lead geometry enable reliable vision-based placement and solder joint formation in high-volume manufacturing.
What is the typical forward voltage of HS1MF-T at 1.0 A and 125°C?
The typical forward voltage of HS1MF-T is 1.02 V at 1.0 A and 125°C, with a maximum of 1.27 V under the same conditions. This value is measured per TSC's electrical specifications table and reflects stable conduction performance at elevated temperatures - critical for maintaining efficiency in enclosed or high-ambient-temperature power systems where thermal derating of Schottky alternatives becomes problematic.
How does the reverse recovery time of HS1MF-T compare to lower-voltage variants in the same family?
The HS1MF-T has a reverse recovery time (trr) of ≤75 ns, matching HS1JF-T and HS1KF-T, while HS1GF-T and HS1DF-T specify ≤50 ns. This reflects the trade-off between higher voltage capability and carrier lifetime control: the 1000 V HS1MF-T uses optimized doping and junction design to maintain fast recovery despite increased depletion width, enabling consistent switching behavior across the family's 200–1000 V range.
Is HS1MF-T halogen-free and RoHS compliant?
Yes, HS1MF-T is halogen-free per IEC 61249-2-21 and RoHS compliant per EU Directive 2011/65/EU. The molding compound contains no brominated flame retardants or chlorine-based additives, and all plating and substrate materials meet restricted substance thresholds. Compliance documentation is available through Taiwan Semiconductor's official product change notices and material declarations.
