Product details

Overview

TSDGLWHRVG from Taiwan Semiconductor is a 1 A, 400 V repetitive peak reverse voltage glass-passivated SOD-123W surface-mount rectifier with ≥8 kV HBM ESD rating, 0.90 V forward voltage at 1.0 A/25°C, and 40 A surge current capability-used in DC-DC converter output stages for high-reliability industrial power supplies.

For engineers reviewing the TSDGLWHRVG datasheet, TSDGLWHRVG pinout, TSDGLWHRVG application, or TSDGLWHRVG equivalent, key selection criteria include its SOD-123W package thermal resistance (R_θJL = 25°C/W), JESD201 Class 2 whisker resistance, and verified IEC 61000-4-2 air-discharge immunity up to 25 kV.

Technical Context

This single-die silicon rectifier features a glass-passivated PN junction enabling stable operation from –55°C to +175°C junction temperature, with low leakage (<1 µA @ 25°C) and tight VF tolerance (0.90–1.00 V at 1 A/25°C). Its SOD-123W molding compound meets UL 94V-0 and halogen-free IEC 61249-2-21 standards.

The device is optimized for automated placement and reflow soldering per J-STD-002, with matte tin-plated leads and cathode-band polarity marking. Thermal performance is characterized on a 5 mm × 5 mm Cu pad PCB, delivering R_θJA = 84°C/W under standard test conditions.

FAQ

What is the maximum junction temperature rating for TSDGLWHRVG?

The TSDGLWHRVG has a maximum junction temperature (T_J) of +175°C and a minimum of –55°C. This wide operating range allows the TSDGLWHRVG to function reliably in under-hood automotive environments and high-ambient industrial settings without thermal derating below 1 A continuous current when mounted on a 5 mm × 5 mm copper pad.

Does TSDGLWHRVG meet IEC 61000-4-2 Level 4 ESD requirements?

Yes, the TSDGLWHRVG is tested to IEC 61000-4-2 Level 4, achieving ≥25 kV air-discharge and ≥15 kV contact-discharge immunity. This exceeds standard Level 4 thresholds and eliminates the need for external ESD protection circuitry in lighting drivers and consumer adapters where human interaction occurs.

What is the forward voltage of TSDGLWHRVG at 1 A and 125°C?

The TSDGLWHRVG exhibits a forward voltage of 0.77 V (typical) and ≤1.00 V (maximum) at 1 A and 125°C. This low, thermally stable V_F ensures consistent conduction loss across temperature, supporting high-efficiency operation in thermally demanding LED driver and DC-DC converter applications.

Is TSDGLWHRVG compatible with lead-free reflow soldering processes?

Yes, the TSDGLWHRVG uses matte tin-plated leads compliant with J-STD-002 and is qualified for lead-free reflow soldering with a peak temperature of 260°C for up to 10 seconds. Its SOD-123W package is designed for compatibility with standard automated assembly lines and IPC-A-610 Class 2/3 acceptance criteria.

What is the reverse leakage current of TSDGLWHRVG at 125°C?

The TSDGLWHRVG specifies a maximum reverse leakage current (I_R) of 50 µA at 125°C and rated reverse voltage. This low leakage preserves efficiency in high-temperature LED drivers and ensures minimal standby power loss in always-on industrial power modules.
