Product details

Overview

S15GLWHRVG from Taiwan Semiconductor is a 1.5A, 400V repetitive peak reverse voltage (V_RRM) standard surface-mount silicon rectifier diode in SOD-123W package, featuring 50A surge capability (I_FSM), 175°C max junction temperature, and low forward voltage drop of 0.98V at 1.5A/25°C - used in DC-DC converters and switching-mode power supplies.

For engineers reviewing the S15GLWHRVG datasheet, S15GLWHRVG pinout, S15GLWHRVG application, or S15GLWHRVG equivalent, key selection criteria include V_RRM = 400V, I_F = 1.5A, thermal resistance R_θJA = 85°C/W, moisture sensitivity level 1, and RoHS/halogen-free compliance for high-reliability industrial power designs.

Technical Context

This single-die standard rectifier operates with unidirectional conduction and cathode-band polarity indication. Its SOD-123W package enables automated placement and supports JEDEC J-STD-002 solderability and JESD 201 Class 2 whisker resistance.

Thermal performance is characterized with R_θJL = 29°C/W and R_θJC = 31°C/W on a 5mm × 5mm Cu pad test board. Reverse leakage remains ≤1 µA at 25°C and ≤100 µA at 125°C under rated V_R, with junction capacitance of 10 pF at 1 MHz / 4 V.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - maximum repetitive reverse voltage before breakdown; defines safe operating range in flyback/clamp circuits
I_F	1.5 A continuous - average forward current rating at TA = 25°C; derates linearly above 25°C per curve Fig.1
I_FSM	50 A - non-repetitive surge current (8.3 ms half-sine); supports inrush and transient overload handling
V_F	0.98 V max @ 1.5A/25°C - low conduction loss improves efficiency in 12–48V output DC-DC stages
T_J max	+175°C - high junction temperature rating enables operation in compact, thermally constrained enclosures
R_θJA	85°C/W - thermal resistance to ambient on standard PCB; informs heatsinking and layout requirements
C_J	10 pF @ 1 MHz / 4 V - low junction capacitance minimizes switching noise and EMI in high-frequency SMPS

Pinout & Package

SOD-123W surface-mount package: molded case meeting UL 94V-0, matte tin-plated leads, cathode indicated by band, weight ≈0.019 g.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry terminal	Connected to lower-potential side (e.g., transformer secondary center-tap or switch node)
Cathode	Forward current exit terminal	Marked with band; ties to output rail or filter capacitor positive; defines polarity in layout

Key Features

Feature	Design Value
Moisture Sensitivity Level 1	Zero bake requirement before reflow; compatible with standard SMT assembly lines without dry-pack handling
RoHS & Halogen-Free	Complies with IEC 61249-2-21 and EU RoHS; eliminates brominated flame retardants and chlorine/bromine content
High Surge Current (50A)	Withstands repeated line transients and startup surges without degradation in telecom or industrial power supplies
Low V_F at High Temp	0.87 V max @ 1.5A/125°C - maintains efficiency and reduces thermal runaway risk in sealed environments
Junction-to-Lead R_θJL	29°C/W - enables direct thermal coupling to copper pour or thermal pad for improved power dissipation

Applications

AC-DC Adapter Power Supply	Industrial DC-DC Converter
Use Scenario: Secondary-side rectification in 12–24V output offline adapters with <10W output power. IC Role / Device Role / Timing Role: Standard rectifier converting transformer AC output to regulated DC; replaces Schottky where higher V_RRM needed. Use Value: 400V V_RRM provides margin against reflected spikes; 0.98V V_F limits conduction loss below 1.5W at full load.	Use Scenario: Output rectification in isolated 48V input → 5V/3.3V DC-DC modules for PLC I/O modules. IC Role / Device Role / Timing Role: Unidirectional current path after isolation transformer; handles continuous 1.5A load with minimal thermal rise. Use Value: R_θJA = 85°C/W and T_J_max = 175°C allow operation up to 85°C ambient without derating on standard FR4.
Switching Inverter Auxiliary Rail	LED Driver Input Rectification
Use Scenario: Bias supply rectification for gate drivers and control ICs in motor inverters (e.g., HVAC compressors). IC Role / Device Role / Timing Role: Converts auxiliary winding AC to stable low-current DC; operates intermittently but must survive high dV/dt. Use Value: 50A I_FSM withstands turn-on transients; 10pF C_J reduces capacitive coupling noise into sensitive analog control sections.	Use Scenario: Bridge or single-diode rectification in constant-current LED drivers for street lighting (100–277V AC input). IC Role / Device Role / Timing Role: Primary-side AC line rectifier feeding bulk capacitor; exposed to full line voltage and surge events. Use Value: 400V V_RRM meets IEC 61000-4-5 surge immunity requirements; halogen-free construction supports outdoor environmental certifications.

Equivalent & Alternatives

The following parts are listed as comparable options for similar standard rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor MUR150	V_RRM = 50V, I_F = 1.5A, faster recovery (t_rr ≈ 75 ns) vs. standard recovery (~2 µs)	Better suited for high-frequency (<100 kHz) flyback; not rated for 400V line-referenced use	Select only when lower V_RRM and faster switching are required; not a voltage replacement for S15GLWHRVG
Vishay VS-1N4007-M3/54	V_RRM = 1000V, I_F = 1.0A, DO-41 through-hole, higher V_F (1.1V @ 1A)	Through-hole mounting; lower current rating; higher conduction loss in SMT designs	Use only for legacy through-hole upgrades or where 1000V margin is mandatory; not SMT-compatible

Compared with MUR150 and VS-1N4007-M3/54, the S15GLWHRVG uniquely balances 400V V_RRM, 1.5A I_F, SOD-123W SMT compatibility, and L1 moisture rating - making it optimal for space-constrained, high-volume industrial power supplies requiring robust surge handling without fast-recovery complexity.

FAQ

What is the peak repetitive reverse voltage rating for S15GLWHRVG?

The S15GLWHRVG has a peak repetitive reverse voltage (V_RRM) rating of 400 V. This value is explicitly defined in the Absolute Maximum Ratings table for the S15GLW variant and confirmed across all electrical and derating curves in the official Taiwan Semiconductor datasheet Version C2103. It ensures reliable blocking during normal operation in 230V AC-derived supplies with safety margin.

Does S15GLWHRVG support lead-free reflow soldering?

Yes, the S15GLWHRVG supports lead-free reflow soldering. Its matte tin-plated leads meet J-STD-002 solderability requirements, and its moisture sensitivity level is rated at Level 1 per J-STD-020 - meaning it can be subjected to standard Pb-free reflow profiles (e.g., JEDEC J-STD-020D peak of 260°C) without baking or special handling.

What is the forward voltage drop of S15GLWHRVG at 1.5A and 125°C?

The forward voltage drop (V_F) of the S15GLWHRVG is 0.87 V maximum at 1.5 A and 125°C, as specified in the Electrical Specifications table under "IF = 1.5A, TJ = 125°C". This lower V_F at elevated temperature improves thermal stability and reduces power loss in high-ambient applications like enclosed power supplies.

Is S15GLWHRVG halogen-free and RoHS compliant?

Yes, the S15GLWHRVG is both halogen-free and RoHS compliant. Taiwan Semiconductor confirms compliance with IEC 61249-2-21 for halogen content and EU Directive 2011/65/EU (RoHS). These attributes are stated in the Features section and verified in the Mechanical Data and Ordering Information pages of the official datasheet.

What package type does S15GLWHRVG use, and what are its key mechanical properties?

The S15GLWHRVG uses the SOD-123W surface-mount package. Key mechanical properties include UL 94V-0 flammability-rated molding compound, matte tin-plated leads, cathode polarity indicated by a band, and a typical weight of 0.019 g. The package is optimized for automated placement and meets JESD 201 Class 2 whisker resistance requirements.
