Product details
Overview
HS1B M2G from Taiwan Semiconductor is a 1 A, 100 V glass-passivated surface-mount silicon rectifier diode in DO-214AC (SMA) package, featuring 30 A peak surge current, 150 °C max junction temperature, and 1.0 V typical forward voltage at 1 A - used in DC/DC converters and snubber circuits.
For engineers reviewing the HS1B M2G datasheet, HS1B M2G pinout, HS1B M2G application, or HS1B M2G equivalent, key selection criteria include repetitive peak reverse voltage (100 V), thermal resistance (RθJL = 15 °C/W), reverse recovery time (≤50 ns), and RoHS/halogen-free compliance for industrial power conversion designs.
Technical Context
This device is a single-die, unidirectional, fast-recovery silicon rectifier optimized for high-efficiency switching-mode power supplies. Its glass-passivated junction ensures stable leakage performance up to 125 °C, with IR ≤ 50 µA at TJ = 100 °C.
The DO-214AC (SMA) package supports automated placement and provides 70 °C/W junction-to-ambient thermal resistance on a 5 mm × 5 mm copper pad. Polarity is marked by a cathode band; terminals are matte tin-plated per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse voltage before breakdown; defines safe operating range in flyback and snubber applications |
| IF | 1 A continuous - average forward current rating at 75 °C ambient; determines steady-state power handling capability |
| IFSM | 30 A - non-repetitive surge current for 8.3 ms half-sine; enables robustness against line transients and inrush |
| VF @ 1 A | 1.0 V typical - forward voltage drop at rated current; directly impacts conduction loss and thermal design |
| trr | ≤50 ns - reverse recovery time under IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; critical for high-frequency switching efficiency |
| RθJL | 15 °C/W - junction-to-lead thermal resistance; enables direct thermal path to PCB copper for reliable power dissipation |
| Junction temp | –55 to +150 °C - operational range; supports industrial environments without derating below –40 °C |
Pinout & Package
DO-214AC (SMA) surface-mount package with axial lead configuration: two terminals - anode and cathode - polarity indicated by molded cathode band. Weight ≈ 0.060 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of circuit; must handle full 1 A DC and 30 A surge |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; withstands 100 V reverse bias; low capacitance (20 pF @ 4 V) minimizes switching noise |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enables stable IR ≤ 5 µA at 25 °C and ≤ 150 µA at 125 °C - critical for high-temp reliability in enclosed power modules |
| Fast recovery (≤50 ns) | Reduces switching losses in 100–500 kHz SMPS designs, improving efficiency over standard rectifiers |
| Moisture sensitivity level 1 | Eliminates bake requirement prior to reflow; compatible with standard SMT assembly lines without special handling |
| RoHS & halogen-free | Meets IPC-1752A material declaration requirements for automotive and industrial end-equipment compliance |
| DO-214AC mechanical robustness | UL 94V-0 molding compound and JESD201 Class 2 whisker resistance ensure long-term solder joint integrity |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-efficiency rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR110T3G | 100 V VRRM, 1 A IF, 1.25 V VF @ 1 A, 75 ns trr, TO-277 package | Higher VF increases conduction loss; slower recovery limits >200 kHz use | Preferred when TO-277 footprint compatibility required; not drop-in for SMA layout |
| Vishay VS-1EWH06-M3/5AT | 60 V VRRM, 1 A IF, 0.92 V VF @ 1 A, 35 ns trr, SMA package | Lower voltage rating restricts use to ≤60 V circuits; faster recovery improves high-frequency efficiency | Select for 24–48 V systems needing lowest possible trr; requires redesign if VRRM margin < 2× input |
Compared with MUR110T3G and VS-1EWH06-M3/5AT, HS1B M2G delivers optimal balance of 100 V rating, 1.0 V VF, and 50 ns trr in standard SMA - making it ideal for cost-sensitive 100 V-class industrial DC/DC and snubber designs where thermal resistance and moisture robustness are critical.

FAQ
What is the maximum junction temperature rating for HS1B M2G?
The HS1B M2G has a maximum junction temperature (TJ) of +150 °C and a minimum of –55 °C. This wide operating range allows deployment in industrial environments without additional thermal derating below –40 °C. The device maintains specified electrical parameters within this range, and its RθJL of 15 °C/W enables effective heat transfer to the PCB when mounted on a 5 mm × 5 mm copper pad.
Does HS1B M2G have a halogen-free and RoHS-compliant construction?
Yes, HS1B M2G is both RoHS compliant and halogen-free, meeting IPC-1752A material declaration standards. The molding compound is UL 94V-0 rated, and the matte tin-plated leads comply with J-STD-002 for solderability. These attributes make HS1B M2G suitable for environmentally regulated end equipment including industrial automation and commercial lighting.
What is the reverse recovery time (trr) specification for HS1B M2G?
The HS1B M2G has a reverse recovery time (trr) of ≤50 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This fast recovery characteristic reduces switching losses in high-frequency power converters, supporting efficient operation up to 300 kHz in well-designed layouts with minimized parasitic inductance.
Is HS1B M2G suitable for automated SMT assembly?
Yes, HS1B M2G is explicitly designed for automated placement. It carries J-STD-020 Moisture Sensitivity Level 1 (MSL-1), eliminating pre-bake requirements. Its DO-214AC (SMA) package features precise dimensional control, matte tin-plated leads, and a cathode band for optical recognition - all verified for compatibility with high-speed pick-and-place systems and lead-free reflow profiles.
What marking code identifies HS1B M2G on the device body?
The HS1B M2G is marked with "HS1B" on the device body, followed by date code and factory identifier per TSC's standard marking diagram (e.g., "HS1B YW F"). The cathode is indicated by a distinct band. This marking aligns with JEDEC DO-214AC packaging standards and enables traceability to the M2401 revision of the datasheet.
