Product details
Overview
TSD1GLW from Taiwan Semiconductor is a 1 A, 400 V repetitive peak reverse voltage (VRRM) glass-passivated ESD-hardened rectifier diode in SOD-123W package, featuring 0.90 V forward voltage at 1.0 A and 25°C, 30 A surge current capability, and AEC-Q101-001 H3B-class ESD immunity (≥8 kV HBM), used for polarity protection in automotive body electronics and industrial power supplies.
For engineers reviewing the TSD1GLW datasheet, TSD1GLW pinout, TSD1GLW application, or TSD1GLW equivalent, key selection criteria include its 400 V VRRM, 1 A continuous forward current rating, SOD-123W footprint compatibility, low thermal resistance (RθJL = 15 °C/W), and validated ESD robustness per IEC 61000-4-2 contact mode (≥10 kV).
Technical Context
This device is a single-die, unidirectional silicon rectifier with glass-passivated junction for enhanced reliability under humidity and thermal stress. Its 175°C maximum junction temperature and JESD201 Class 2 whisker resistance support operation in high-temperature automotive under-hood environments.
The SOD-123W package enables automated placement and provides UL 94V-0 flammability compliance. Cathode band polarity marking and matte tin-plated leads ensure solderability per J-STD-002, while RθJA = 75 °C/W is measured on a 5 mm × 5 mm Cu pad PCB test board.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR120SFT1G | 200 V VRRM, 1 A, TO-277 package (larger footprint), 0.92 V VF @ 1 A | Lower voltage rating limits use to ≤200 V circuits; TO-277 requires larger PCB area and different thermal management | Select when higher surge rating (50 A IFSM) is prioritized over space and ESD robustness |
| Vishay VS-1EWH04-M3/5AT | 400 V VRRM, 1 A, SOD-123FL package, 0.95 V VF @ 1 A, no AEC-Q101 validation | Same voltage/current rating but lacks automotive-grade ESD certification and JESD201 whisker compliance | Select for cost-sensitive consumer applications where AEC-Q101 and IEC 61000-4-2 are not required |
Compared with MUR120SFT1G and VS-1EWH04-M3/5AT, the TSD1GLW uniquely combines 400 V rating, SOD-123W miniaturization, AEC-Q101 H3B ESD qualification, and JESD201 Class 2 whisker resistance-making it optimal for space-constrained, automotive-qualified polarity protection where reliability under thermal and electrostatic stress is critical.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for TSD1GLW?
The TSD1GLW has a maximum repetitive peak reverse voltage (VRRM) of 400 V, as confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version A2309). This value is fixed for the TSD1GLW variant and differs from the 600 V rating of the TSD1JLW version. Exceeding 400 V in continuous reverse bias risks irreversible junction breakdown.
Does TSD1GLW meet AEC-Q101 reliability standards?
Yes, the TSD1GLW is qualified to AEC-Q101-001 for Human Body Model (HBM) ESD testing at Class H3B (≥8 kV), as explicitly stated in the Immunity to Electrical Static Discharge section of the datasheet. It also meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity, fulfilling core automotive qualification requirements.
What is the forward voltage (VF) of TSD1GLW at 1.0 A and 125°C?
The forward voltage of TSD1GLW is 0.78 V at 1.0 A forward current and 125°C junction temperature, per the Electrical Specifications table. This lower VF compared to room-temperature operation reflects the negative temperature coefficient of silicon diodes and supports stable performance in high-ambient-temperature applications such as engine control units.
Is TSD1GLW compatible with lead-free reflow soldering processes?
Yes, TSD1GLW features matte tin-plated leads compliant with J-STD-002 for solderability and is rated at Moisture Sensitivity Level 1 per J-STD-020, meaning it can be subjected to standard lead-free reflow profiles (e.g., JEDEC J-STD-020 peak of 260°C) without baking or special handling.
What is the thermal resistance from junction to ambient (RθJA) for TSD1GLW?
The junction-to-ambient thermal resistance (RθJA) of TSD1GLW is 75 °C/W, measured on a standard 5 mm × 5 mm copper pad PCB test board. This value assumes natural convection and defines the worst-case thermal rise from junction to ambient air under steady-state 1 A conduction, guiding heatsinking and layout decisions.
