Product details
Overview
TSD1GLWH from Taiwan Semiconductor is a 1A, 400V repetitive peak reverse voltage glass-passivated SOD-123W surface-mount rectifier diode with AEC-Q101 qualification, 8kV HBM ESD rating, and 0.90V max forward voltage at 1.0A/25°C. It serves as a polarity protection and general-purpose rectification device in automotive body electronics and industrial power supplies.
For engineers reviewing the TSD1GLWH datasheet, TSD1GLWH pinout, TSD1GLWH application, or TSD1GLWH equivalent, key selection criteria include its 400V VRRM, 30A IFSM, 175°C maximum junction temperature, SOD-123W package compatibility with automated placement, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This single-die standard recovery rectifier features a glass-passivated PN junction optimized for low forward voltage (0.90V max @ 1A/25°C) and high ESD immunity (≥8kV HBM per AEC-Q101-001). Its thermal design supports 15°C/W junction-to-lead resistance when mounted on a 5mm × 5mm copper pad.
The device operates across –40°C to +175°C junction temperature range and delivers ≤1µA reverse leakage at 25°C and rated 400V reverse voltage. Junction capacitance is 11pF at 1MHz/4V, supporting stable performance in moderate-frequency rectification circuits.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for the TSD1GLWH?
The TSD1GLWH has a maximum repetitive peak reverse voltage (VRRM) of 400 V. This rating is confirmed in the Absolute Maximum Ratings table and defines the highest reverse voltage the device can block repeatedly without breakdown. It is critical for selecting appropriate derating margins in 12V or 24V automotive and industrial systems where load dump or inductive kick may exceed nominal bus voltage.
Is the TSD1GLWH qualified for automotive applications?
Yes, the TSD1GLWH is AEC-Q101 qualified, as explicitly stated in the FEATURES section and verified in the ESD immunity test summary. This qualification covers stress tests including HBM ESD ≥8kV, temperature cycling, and high-temperature operating life-making the TSD1GLWH suitable for automotive body electronics, lighting, and infotainment power rails where reliability under thermal and electrical stress is mandatory.
What is the forward voltage (VF) of the TSD1GLWH at 1.0A and 25°C?
The TSD1GLWH exhibits a maximum forward voltage (VF) of 1.10 V at 1.0A and 25°C, with a typical value of 0.90 V under the same conditions. This value is specified in the Electrical Specifications table and directly impacts conduction loss and thermal design-enabling efficient operation in space-constrained 1A rectification applications without forced cooling.
Which package does the TSD1GLWH use, and what are its key mechanical attributes?
The TSD1GLWH uses the SOD-123W package, a JEDEC DO-219 AB-compliant surface-mount outline with matte tin-plated leads, UL 94V-0 flammability rating, and moisture sensitivity level 1 per J-STD-020. Its dimensions (2.90 × 1.40 × 1.02 mm) and cathode band marking support automated placement and visual polarity verification during inspection and rework.
Does the TSD1GLWH have enhanced ESD protection, and what standards does it meet?
Yes, the TSD1GLWH provides enhanced ESD protection with ≥8kV rating per Human Body Model (HBM) per AEC-Q101-001, plus ≥10kV contact discharge per IEC 61000-4-2 and ≥10kV per ISO 10605. These ratings are measured and documented in the Immunity to Electrical Static Discharge section, confirming suitability for assembly environments and end-use applications prone to electrostatic events.
