Product details

Overview

S1JLH from Taiwan Semiconductor is a 1A, 600V repetitive peak reverse voltage (V_RRM) standard surface-mount silicon rectifier diode in Sub SMA package, featuring glass passivated junction, AEC-Q101 qualification, and 1800 ns reverse recovery time - used in automotive DC-DC converters and snubber circuits.

For engineers reviewing the S1JLH datasheet, S1JLH pinout, S1JLH application, or S1JLH equivalent, key selection criteria include its 600V V_RRM, 1A average forward current, 30A I_FSM, -55°C to +175°C operating junction temperature, and AEC-Q101 qualification for automotive reliability.

Technical Context

The S1JLH is a single-die, unidirectional standard recovery rectifier with cathode-band polarity marking and matte tin-plated leads compliant with J-STD-002 solderability. Its 1800 ns reverse recovery time and 9 pF junction capacitance at 1 MHz/4.0 V define switching behavior in moderate-frequency snubbers and flyback clamp networks.

Thermally, it exhibits 25°C/W junction-to-lead resistance (R_θJL) and 85°C/W junction-to-ambient resistance (R_θJA). It operates across -55°C to +175°C storage and junction temperature ranges, with moisture sensitivity level 1 per J-STD-020.

Key Specifications

I_F	1 A - continuous average forward current rating at T_A = 25°C
I_FSM	30 A - peak surge current capability for 8.3 ms half-sine wave
V_F	1.1 V max @ I_F = 1 A, T_J = 25°C - forward conduction loss at rated current
t_rr	1800 ns - reverse recovery time under IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A
T_J max	+175°C - maximum allowable junction temperature for reliable operation

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1L60S	600 V V_RRM, 1 A I_F, but faster t_rr = 75 ns; TO-277 package	Higher-frequency PFC or synchronous rectifier replacement; requires different footprint	Select when faster recovery is needed and layout allows TO-277 mounting
ES1J	600 V V_RRM, 1 A I_F, t_rr = 350 ns; SMA package, not AEC-Q101 qualified	Cost-sensitive consumer or industrial supplies where automotive qualification is unnecessary	Choose for non-automotive use with tighter t_rr requirement and same Sub SMA footprint

Compared with STTH1L60S and ES1J, the S1JLH offers AEC-Q101 compliance and optimized thermal resistance (25°C/W R_θJL) for sustained 1 A operation in automotive environments, while ES1J provides faster recovery in identical packaging and STTH1L60S delivers ultrafast performance in a larger outline.

FAQ

What is the peak repetitive reverse voltage rating of the S1JLH?

The S1JLH has a peak repetitive reverse voltage (V_RRM) rating of 600 V, verified per Taiwan Semiconductor's B2108 datasheet revision. This value defines the maximum reverse-biased voltage the diode can block repeatedly without avalanche breakdown. The S1JLH is part of the S1ALH–S1MLH series where 'J' corresponds to the 600 V grade, confirmed by the marking code '1JL' on the device body.

Is the S1JLH suitable for automotive applications?

Yes, the S1JLH is explicitly AEC-Q101 qualified per its datasheet, making it suitable for automotive applications including engine control units, body electronics, and lighting systems. Its -55°C to +175°C operating junction temperature range, glass passivated junction, and moisture sensitivity level 1 support harsh automotive environments. The S1JLH meets all stress tests defined in AEC-Q101, including HTGB, HTRB, and temperature cycling.

What package type does the S1JLH use, and what are its key mechanical attributes?

The S1JLH uses the Sub SMA package - a low-profile surface-mount outline with matte tin-plated leads compliant with J-STD-002, UL 94V-0 flammability-rated molding compound, and cathode band polarity marking. Its weight is approximately 0.019 g, and it supports automated placement. The Sub SMA footprint matches industry-standard SMA pads, though dimensions are slightly reduced versus full-size SMA.

What is the reverse recovery time (t_rr) of the S1JLH, and how does it affect circuit performance?

The S1JLH has a reverse recovery time (t_rr) of 1800 ns under test conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This relatively long t_rr indicates standard (not fast or ultrafast) recovery behavior, making the S1JLH appropriate for line-frequency and low-to-moderate switching frequency applications (e.g., ≤50 kHz snubbers or 50/60 Hz rectification), but not for high-frequency SMPS outputs.

Does the S1JLH have any environmental or compliance certifications?

Yes, the S1JLH is RoHS compliant and halogen-free per IEC 61249-2-21. It also meets JESD201 Class 2 whisker resistance and has moisture sensitivity level 1 per J-STD-020 - meaning it can be stored indefinitely before reflow without baking. These certifications are documented in the official Taiwan Semiconductor S1ALH–S1MLH datasheet Version B2108.
