Product details
Overview
HS1MFSH from Taiwan Semiconductor is a 1000V, 1A surface-mount fast recovery rectifier in SOD-128 package, featuring 75 ns reverse recovery time, 1.49 V forward voltage at 1.0 A and 25°C, and AEC-Q101 qualification for automotive use in DC/DC converters and snubber circuits.
For engineers reviewing the HS1MFSH datasheet, HS1MFSH pinout, HS1MFSH application, or HS1MFSH equivalent, key selection criteria include peak reverse voltage (1000 V), thermal resistance (RθJL = 29 °C/W), junction temperature range (–55 to +150 °C), and low-profile SOD-128 packaging for high-density power layouts.
Technical Context
The HS1MFSH is a single-die, glass-passivated silicon rectifier optimized for fast switching and low conduction loss in high-voltage DC/DC conversion stages. Its 1000 V VRRM, 35 A IFSM (8.3 ms), and 75 ns trr support robust operation under repetitive surge and transient conditions.
Thermally, it delivers RθJL = 29 °C/W and RθJC = 22 °C/W when mounted on a 5 mm × 5 mm copper pad, enabling reliable 1 A continuous forward current up to +150 °C junction temperature with minimal derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - supports input rails up to 700 V DC in offline or industrial DC/DC designs |
| IF | 1 A continuous - rated for sustained output current in compact auxiliary or bias supplies |
| trr | 75 ns - enables efficient high-frequency switching (>100 kHz) with reduced switching loss |
| VF @ 1.0 A, 25°C | 1.49 V typical - defines conduction loss of ~1.49 W at full load, critical for thermal budgeting |
| RθJL | 29 °C/W - allows direct thermal coupling to PCB copper, simplifying heatsinking in space-constrained layouts |
| IR @ 1000 V, 125°C | 35 µA max - ensures low leakage in high-temperature automotive environments |
| CJ @ 1 MHz, 4 V | 8 pF - minimizes capacitive loading and EMI in fast-switching node applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-1N5819HM3/85A | 40 V VRRM, 1 A, Schottky; no AEC-Q101, higher leakage at 125°C | Not suitable for >100 V applications; limited to low-voltage DC/DC | Select only for sub-40 V, low-loss, non-automotive bias rails |
| ON Semiconductor MUR1100E | 1000 V VRRM, 1 A, 100 ns trr, TO-277 package (larger footprint) | Slower recovery increases switching loss above 100 kHz; requires more PCB area | Prefer when legacy TO-277 layout exists and 75 ns speed is not required |
Compared with VS-1N5819HM3/85A and MUR1100E, the HS1MFSH uniquely combines AEC-Q101 qualification, 75 ns recovery, and SOD-128 form factor-enabling automotive-grade performance in space-constrained, high-frequency 1000 V rectification where leakage, thermal resistance, and reliability are critical.

FAQ
What is the maximum junction temperature rating for HS1MFSH?
The HS1MFSH has a maximum junction temperature (TJ) of +150 °C and a minimum of –55 °C. This wide operating range supports deployment in under-hood automotive environments and industrial enclosures without active cooling. Derating begins above 75 °C ambient per the forward current derating curve in the datasheet. The HS1MFSH must be mounted on a 5 mm × 5 mm copper pad to achieve its specified RθJA = 51 °C/W.
Is HS1MFSH pin-compatible with other parts in the HS1xFSH series?
Yes, all HS1xFSH variants-including HS1DFSH, HS1GFSH, HS1JFSH, HS1KFSH, and HS1MFSH-share identical SOD-128 package dimensions, pinout, and solder pad layout. The only differences are VRRM rating and associated electrical parameters (e.g., VF, trr, CJ). This allows design reuse across voltage grades without PCB revision.
Does HS1MFSH meet automotive reliability standards?
Yes, the HS1MFSH is AEC-Q101 qualified, tested for temperature cycling, humidity bias, mechanical shock, and whisker resistance (JESD 201 Class 2). It also meets J-STD-020 moisture sensitivity level 1, eliminating bake requirements prior to reflow. These qualifications confirm suitability for automotive powertrain and body electronics applications.
What is the reverse recovery time (trr) of HS1MFSH and how is it measured?
The HS1MFSH has a typical reverse recovery time (trr) of 75 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value applies to the HS1JFSH, HS1KFSH, and HS1MFSH variants per the datasheet's Electrical Specifications table. Faster recovery reduces switching loss and EMI in high-frequency converters.
Can HS1MFSH be used in surface-mount reflow processes?
Yes, the HS1MFSH is qualified for standard lead-free reflow soldering per J-STD-020. Its matte tin-plated leads are solderable, and its moisture sensitivity level is 1-meaning it can be stored indefinitely at ≤30 °C/60% RH without baking. The SOD-128 package is compatible with automated pick-and-place and reflow profiles up to 260 °C peak temperature.
