Product details

Overview

ES2DALH from Taiwan Semiconductor is a 2 A, 200 V super fast surface-mount rectifier diode in a Thin SMA package, featuring 35 ns reverse recovery time, 0.88 V forward voltage at 2 A/25°C, and AEC-Q101 qualification for automotive use in snubber and freewheeling circuits.

For engineers reviewing the ES2DALH datasheet, ES2DALH pinout, ES2DALH application, or ES2DALH equivalent, key selection criteria include repetitive peak reverse voltage (200 V), surge current capability (50 A @ 8.3 ms), thermal resistance (R_θJL = 24 °C/W), junction temperature range (–55 to +150 °C), and RoHS/halogen-free compliance.

Technical Context

This super fast rectifier uses a glass-passivated silicon die optimized for low forward voltage and rapid switching, enabling high-efficiency operation in DC/DC converters and automotive power supplies where fast turn-off minimizes switching losses.

Its single-die configuration in a Thin SMA package supports automated placement and delivers stable performance across –55°C to +150°C junction temperature, with moisture sensitivity level 1 and JESD201 Class 2 whisker resistance.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH2R02	V_RRM = 200 V, t_rr = 30 ns, V_F = 0.95 V @ 2 A, same Thin SMA package	Slightly faster recovery but higher V_F; lower IR at 125°C (10 µA vs. 25 µA)	Prefer when lowest EMI is critical and higher conduction loss is acceptable.
SB220	V_RRM = 200 V, t_rr = 50 ns, V_F = 0.85 V @ 2 A, SMA package (not Thin SMA)	Slower recovery increases switching loss; thicker package limits board space and thermal performance	Acceptable for lower-frequency (<50 kHz) designs where cost is prioritized over size or speed.

Compared with STTH2R02 and SB220, ES2DALH offers balanced trade-offs: 35 ns t_rr supports medium-frequency switching, 0.88 V V_F maintains efficiency, and Thin SMA packaging enables high-density automotive layouts with verified AEC-Q101 compliance.

FAQ

What is the maximum repetitive peak reverse voltage rating for ES2DALH?

The ES2DALH has a maximum repetitive peak reverse voltage (V_RRM) of 200 V, as specified in the absolute maximum ratings table. This value defines the highest reverse-biased voltage the device can block repeatedly without breakdown under normal operating conditions. Exceeding 200 V risks irreversible junction failure. The ES2DALH is part of a family spanning 100 V to 600 V, with ES2DALH specifically assigned to the 200 V grade.

Is ES2DALH qualified for automotive applications?

Yes, ES2DALH is AEC-Q101 qualified, meaning it has passed rigorous stress tests including temperature cycling, high-temperature reverse bias, and mechanical shock required for automotive under-hood and cabin electronics. Its –55°C to +150°C junction temperature range, glass passivation, and moisture sensitivity level 1 further support automotive deployment. ES2DALH is explicitly listed in TSC's AEC-Q101 documentation for this family.

What is the forward voltage of ES2DALH at 2 A and 125°C?

At 2 A forward current and 125°C junction temperature, the ES2DALH exhibits a typical forward voltage (V_F) of 0.74 V, with a maximum of 0.84 V per the electrical specifications table. This lower V_F at elevated temperature reflects the negative temperature coefficient of silicon diodes and is critical for thermal stability in high-ambient environments like engine control units.

Does ES2DALH have a halogen-free and RoHS-compliant construction?

Yes, ES2DALH meets both RoHS Directive 2011/65/EU and IEC 61249-2-21 halogen-free requirements. The molding compound, lead finish (matte tin), and internal materials are certified halogen-free, and all substances restricted under RoHS are below threshold limits. This compliance is documented in TSC's material declarations and applies to all units marked "ES2DALH" in the B2103 revision.

What is the reverse recovery time (t_rr) specification for ES2DALH?

The ES2DALH has a maximum reverse recovery time (t_rr) of 35 ns, measured at I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This parameter is guaranteed across temperature and confirms its classification as a super fast rectifier. The 35 ns t_rr enables efficient operation in switching power supplies operating up to several hundred kHz without significant commutation loss.
