Product details

Overview

SDLWH from Taiwan Semiconductor is a 0.8A, 200V repetitive peak reverse voltage (V_RRM) standard surface-mount rectifier in SOD-123W package, featuring glass passivated junction, AEC-Q101 qualification, and 150°C maximum junction temperature - used in automotive lighting and DC-DC converter snubber circuits.

For engineers reviewing the SDLWH datasheet, SDLWH pinout, SDLWH application, or SDLWH equivalent, key selection criteria include its 20A I_FSM, 0.94V typical forward voltage at 0.8A/25°C, J-STD-020 Level 1 moisture sensitivity, UL 94V-0 molding compound, and cathode-band polarity marking for reliable automated placement.

Technical Context

This single-die standard rectifier operates with a maximum junction temperature of 150°C and thermal resistance R_θJL = 30°C/W when mounted on a 5mm × 5mm copper pad. Its V_F ranges from 0.77V to 1.10V depending on current and temperature, while reverse leakage stays ≤1 µA at 25°C and ≤150 µA at 125°C under rated V_RRM.

The device uses a glass-passivated PN junction for robustness, supports automated SMT assembly, and meets AEC-Q101 stress testing for automotive use. Its SOD-123W package includes matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - Maximum repetitive reverse voltage the device blocks without breakdown; defines minimum system isolation rating.
I_F	0.8 A - Continuous average forward current rating at 25°C ambient; derates linearly above 25°C per curve Fig.1.
I_FSM	20 A - Peak non-repetitive surge current capability (8.3ms half-sine); critical for inrush and transient protection design.
V_F @ 0.8A, 25°C	0.94 V (typ), 1.10 V (max) - Forward conduction loss directly impacts efficiency and thermal rise in power path.
T_J max	+150 °C - Maximum allowable junction temperature; enables operation in under-hood automotive environments.
R_θJL	30 °C/W - Junction-to-lead thermal resistance; determines temperature rise from power dissipation to PCB copper pad.
C_J	7 pF - Junction capacitance at 1 MHz / 4V reverse bias; affects high-frequency switching noise and snubber tuning.

Pinout & Package

Package: SOD-123W - Surface-mount plastic case with cathode band marking, 5mm × 5mm Cu pad thermal reference, UL 94V-0 flammability rating, and matte tin-plated leads.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to lower-potential side of circuit; must handle full I_F and I_FSM with adequate trace width.
Cathode (marked by band)	Forward current exit / reverse blocking terminal	Polarity indicator ensures correct orientation during automated placement; reverse-biased during off-state to block 200V.

Key Features

Feature	Design Value

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 MURS0820T3G	Same SOD-123W package, 200V V_RRM, but ultrafast recovery (t_rr = 25ns); higher V_F (1.15V typ @ 0.8A).	Better suited for high-frequency switching where reverse recovery time matters; less optimal for low-loss DC output stages.	Select MURS0820T3G only if t_rr < 50ns is required; otherwise SDLWH offers lower conduction loss.
Vishay VS-2EDH02-M3/84A	SOD-123FL package (slightly smaller footprint), same 200V/0.8A rating, but not AEC-Q101 qualified; higher R_θJA (100°C/W).	Limited to industrial or consumer use; unsuitable for automotive due to missing qualification and inferior thermal performance.	Choose VS-2EDH02-M3/84A only for cost-sensitive non-automotive designs where AEC-Q101 is not mandated.

Compared with MURS0820T3G and VS-2EDH02-M3/84A, SDLWH uniquely combines AEC-Q101 qualification, J-STD-020 Level 1 handling, and lowest V_F among 200V SOD-123W rectifiers - making it the preferred choice for thermally constrained, automotive-grade power conversion.

FAQ

What is the maximum junction temperature rating for SDLWH?

The SDLWH has a maximum junction temperature (T_J) rating of +150°C, verified per AEC-Q101 stress testing. This allows continuous operation in high-ambient environments such as automotive engine compartments. Thermal design must ensure that power dissipation - calculated from I_F² × R_F and V_F × I_F - does not exceed limits defined by R_θJL = 30°C/W and PCB copper area.

Is SDLWH suitable for automotive applications?

Yes, SDLWH is AEC-Q101 qualified and explicitly listed for automotive applications including car lighting and body control modules. It meets JESD 201 Class 2 whisker resistance, J-STD-020 Level 1 moisture sensitivity, and UL 94V-0 flammability - all mandatory for Tier-1 automotive supply chain compliance. Its 150°C T_J max and glass passivation further support under-hood reliability.

What does the "DLW" marking code on SDLWH indicate?

The "DLW" marking code on SDLWH identifies it as the 200V variant within the SxLWH family (S = standard, D = 200V, L = low leakage, W = SOD-123W package). This matches the absolute maximum ratings table where SDLWH corresponds to V_RRM = 200V and marking "DLW". The date code (YW) and factory code (F) follow this marking per TSC's standard SOD-123W labeling convention.

How does SDLWH compare to higher-voltage variants like SMLWH?

SDLWH shares identical package (SOD-123W), thermal performance (R_θJL = 30°C/W), and electrical test conditions with SMLWH, but differs in V_RRM (200V vs. 1000V), V_R(RMS) (140V vs. 700V), and reverse leakage (same max values but tested at different voltages). All variants maintain 0.8A I_F, 20A I_FSM, and AEC-Q101 qualification - enabling direct layout reuse across voltage grades when derating permits.

What is the forward voltage specification for SDLWH at elevated temperature?

At 0.8A and 125°C junction temperature, SDLWH exhibits a typical forward voltage (V_F) of 0.84V with a maximum of 1.01V. This represents a ~10% reduction from its 25°C value (0.94V typ), due to negative temperature coefficient of silicon PN junctions. Designers must use this lower V_F in thermal simulations to avoid overestimating conduction loss at operating temperature.
