Product details

Overview

ESDLWH from Taiwan Semiconductor is a 0.8A, 200V repetitive peak reverse voltage (V_RRM) super fast surface-mount rectifier in SOD-123W package, featuring 35ns reverse recovery time (t_rr), 0.85V forward voltage at 0.8A/25°C, and AEC-Q101 qualification for automotive use in snubber and freewheeling circuits.

For engineers reviewing the ESDLWH datasheet, ESDLWH pinout, ESDLWH application, or ESDLWH equivalent, key selection criteria include V_RRM = 200V, t_rr ≤ 35ns, I_F = 0.8A, thermal resistance R_θJA = 88°C/W, and SOD-123W package compatibility with automated placement and J-STD-020 Level 1 moisture sensitivity.

Technical Context

This single-die, glass-passivated silicon rectifier delivers super-fast switching performance with low forward voltage drop and minimal junction capacitance (21pF at 4V). Its 35ns reverse recovery time enables high-frequency operation in DC-DC converters and snubbers without excessive switching loss.

The device operates across –55°C to +150°C junction temperature range and supports automotive-grade reliability via AEC-Q101 qualification, matte tin-plated leads compliant with J-STD-002, and JESD201 Class 2 whisker resistance - all within a low-profile SOD-123W package rated UL 94V-0.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH0.8L02W	V_RRM = 200V, I_F = 0.8A, t_rr = 30ns, VF = 0.82V @ 0.8A - slightly faster but not AEC-Q101 qualified	Lacks automotive qualification; suitable for industrial DC-DC but not underhood lighting or safety-critical modules	Select when AEC-Q101 is not required and <5ns t_rr reduction justifies sourcing from STMicroelectronics
SB0820	V_RRM = 200V, I_F = 0.8A, t_rr = 35ns, VF = 0.87V @ 0.8A - identical recovery and rating, but no AEC-Q101 or JESD201 whisker data	No automotive qualification documentation; limited to commercial-temperature applications only (–40°C to +125°C)	Acceptable for non-automotive consumer or industrial power supplies where full AEC-Q101 traceability is not mandated

Compared with STTH0.8L02W and SB0820, ESDLWH uniquely combines 200V/0.8A super-fast rectification with full AEC-Q101 qualification, JESD201 Class 2 whisker resistance, and J-STD-020 Level 1 moisture sensitivity - making it the only option qualified for automotive lighting and body control unit deployment without derating or additional qualification effort.

FAQ

What is the maximum junction temperature rating for ESDLWH?

The ESDLWH has a maximum junction temperature (T_J_MAX) of +150°C, verified per absolute maximum ratings table. This rating applies across the full operating range and supports sustained 0.8A conduction in automotive underhood environments when mounted on a 5mm × 5mm copper pad. Thermal derating begins above 25°C ambient, as shown in Fig.1 Forward Current Derating Curve.

Is ESDLWH pin-compatible with other devices in the ESxLWH series?

Yes, ESDLWH shares identical SOD-123W package dimensions, anode/cathode pinout, and polarity marking with ESGLWH and ESJLWH. All variants use the same mechanical outline and pad layout, enabling board-level voltage scalability (200V → 400V → 600V) without layout revision - though electrical parameters like V_F and t_rr vary by voltage grade.

Does ESDLWH meet automotive qualification standards?

Yes, ESDLWH is explicitly AEC-Q101 qualified per the manufacturer's datasheet Version A2103. It passes stress tests including high-temperature reverse bias (HTRB), temperature cycling, and unbiased highly accelerated stress test (UHAST), confirming suitability for automotive lighting, body control, and powertrain auxiliary systems.

What is the reverse recovery time (t_rr) specification for ESDLWH?

The ESDLWH has a maximum reverse recovery time (t_rr) of 35ns, measured at I_F = 0.5A, I_R = 1.0A, and I_RR = 0.25A. This value is confirmed in the Electrical Specifications table and enables efficient operation in 100kHz–1MHz DC-DC converters and snubber circuits without significant switching loss or voltage overshoot.

What packaging and moisture sensitivity level does ESDLWH have?

ESDLWH is supplied in SOD-123W package on 10,000-piece tape-and-reel, with moisture sensitivity level (MSL) rated at Level 1 per J-STD-020. This means the device may be stored indefinitely at ≤30°C/60% RH and placed directly into reflow without baking - simplifying SMT line integration for high-volume automotive electronics manufacturing.
