Product details
Overview
S2MFSH from Taiwan Semiconductor is a 1000 V, 2 A standard surface-mount silicon rectifier diode in SOD-128 package, featuring glass-passivated junction, AEC-Q101 qualification, and 50 A surge current rating; used for freewheeling and snubber functions in automotive DC/DC converters.
For engineers reviewing the S2MFSH datasheet, S2MFSH pinout, S2MFSH application, or S2MFSH equivalent, key selection criteria include peak reverse voltage (1000 V), forward voltage at 2 A (≤1.10 V @ 25°C), thermal resistance (RθJL = 14 °C/W), moisture sensitivity level (MSL 1), and AEC-Q101 qualification for automotive reliability.
Technical Context
The S2MFSH is a single-die, unidirectional standard recovery rectifier with cathode-band polarity marking and matte tin-plated leads compliant with J-STD-002 solderability. Its 1000 V VRRM and 2 A average forward current are defined under TA = 25°C with derating above 75°C.
Thermal performance is characterized on a 5 mm × 5 mm copper pad PCB: RθJA = 74 °C/W, RθJC = 20 °C/W, and RθJL = 14 °C/W. Reverse leakage remains ≤33 µA at TJ = 125°C, and junction capacitance is 12 pF at 1 MHz / 4 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - maximum repetitive reverse voltage before breakdown; defines safe operating range in high-voltage DC/DC and snubber circuits |
| IF | 2 A - continuous average forward current at TA = 25°C; requires thermal derating above 75°C ambient |
| IFSM | 50 A - non-repetitive surge current (8.3 ms half-sine); supports transient energy absorption in flyback/freewheeling paths |
| VF @ 2 A, 25°C | ≤1.10 V - forward voltage drop determines conduction loss and thermal load in power stage |
| TJ max | +150°C - maximum junction temperature; enables operation in under-hood automotive environments |
| RθJL | 14 °C/W - junction-to-lead thermal resistance; critical for estimating die temperature rise when lead is used as primary heat path |
Pinout & Package
Package: SOD-128 - low-profile, surface-mount plastic package with molded UL 94V-0 compound, cathode band polarity indicator, and matte tin-plated leads rated for JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of circuit; must withstand 2 A continuous and 50 A surge |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; blocks up to 1000 V reverse bias; leakage ≤33 µA at 125°C junction |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan |
| Glass-passivated junction | Enhances long-term stability and moisture resistance versus epoxy-passivated alternatives |
| MSL Level 1 | Unlimited floor life at ≤30°C/85% RH; eliminates bake requirements prior to reflow |
| Low-profile SOD-128 | 1.1 mm max height enables compact layout in space-constrained automotive modules |
| Halogen-free construction | Complies with IEC 61249-2-21; supports RoHS and ELV compliance in vehicle systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-MBR2100 | Same SOD-128 package, 1000 V VRRM, but Schottky architecture; VF ≈ 0.85 V @ 2 A, 25°C; no reverse recovery charge | Lower conduction loss but higher reverse leakage (>100 µA @ 125°C); unsuitable where low IR is critical | Select for efficiency-critical, low-TJ designs; avoid where reverse leakage must stay ≤33 µA |
| ON Semiconductor MUR2100E | TO-220AC package, 1000 V VRRM, 2 A IF, ultrafast recovery (trr = 75 ns); higher thermal mass but larger footprint | Requires heatsink for >1 A continuous; not surface-mount compatible with SOD-128 land pattern | Select when board-level thermal management permits through-hole mounting and faster recovery is needed |
Compared with VS-MBR2100 and MUR2100E, the S2MFSH offers AEC-Q101 qualification and MSL Level 1 in a low-profile SOD-128 package-making it uniquely suited for automated, high-reliability automotive surface-mount assembly where standard recovery speed and controlled leakage are prioritized over Schottky efficiency or ultrafast switching.

FAQ
What is the peak repetitive reverse voltage rating for S2MFSH?
The S2MFSH has a peak repetitive reverse voltage (VRRM) rating of 1000 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version B2103). It defines the maximum reverse-bias voltage the device can block repeatedly without breakdown, making S2MFSH suitable for high-voltage snubber and DC/DC converter applications where transient spikes approach 800–1000 V.
Is S2MFSH qualified for automotive use?
Yes, S2MFSH is AEC-Q101 qualified per the manufacturer's documentation. This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD), confirming suitability for automotive under-hood and powertrain applications. The S2MFSH's 150°C maximum junction temperature and MSL Level 1 rating further support its deployment in automotive electronics production.
What package type does S2MFSH use, and what are its mechanical highlights?
S2MFSH uses the SOD-128 surface-mount package. Key mechanical features include UL 94V-0 flammability-rated molding compound, matte tin-plated leads compliant with J-STD-002, JESD 201 Class 2 whisker resistance, cathode band polarity marking, and a weight of approximately 0.027 g. Its low profile (max 1.1 mm height) supports dense PCB layouts in automotive modules.
What is the forward voltage of S2MFSH at 2 A and 25°C?
The forward voltage (VF) of S2MFSH is specified as a maximum of 1.10 V at IF = 2 A and TJ = 25°C. The typical value is 0.98 V under the same conditions. This parameter is measured using a pulse test (PW = 0.3 ms) and directly impacts conduction loss and thermal design in power rectification circuits using S2MFSH.
Does S2MFSH have halogen-free and RoHS-compliant construction?
Yes, S2MFSH is both RoHS compliant and halogen-free per IEC 61249-2-21. These environmental attributes are explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet (Version B2103) and verified in the Mechanical Data and Ordering Information sections. This makes S2MFSH suitable for automotive and industrial applications with strict material compliance requirements.
