Product details

Overview

S1JLSH from Taiwan Semiconductor is a 1.2A, 600V standard surface-mount silicon rectifier diode in SOD-123HE package, designed for unidirectional DC power conversion in automotive and industrial power supplies. It features AEC-Q101 qualification, 50A peak surge current capability, 1.3V max forward voltage at 1.2A, and operates up to 175°C junction temperature.

For engineers reviewing the S1JLSH datasheet, S1JLSH pinout, S1JLSH application, or S1JLSH equivalent, key selection criteria include repetitive peak reverse voltage (600V), thermal resistance (R_θJA = 86°C/W), moisture sensitivity level (MSL 1), RoHS/halogen-free compliance, and SOD-123HE footprint compatibility with automated placement systems.

Technical Context

The S1JLSH is a single-die, planar-passivated silicon PN junction rectifier optimized for high-efficiency, medium-voltage DC/DC conversion. Its 600V V_RRM, 1.2A average forward current rating, and 50A I_FSM support robust operation under transient overloads in automotive lighting and snubber circuits.

Thermal performance is defined for mounting on a 5mm × 5mm copper pad: R_θJL = 46°C/W and R_θJC = 50°C/W confirm suitability for thermally constrained PCB layouts. Reverse leakage remains ≤150µA at 125°C, ensuring stable blocking behavior across extended temperature ranges.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - Maximum repetitive reverse voltage the device blocks without breakdown; defines system isolation margin in 48V–400V bus applications.
I_F	1.2 A - Continuous average forward current at T_A = 25°C; derates linearly above 25°C per forward current derating curve.
I_FSM	50 A - Non-repetitive peak surge current (8.3ms half-sine); supports inrush and fault-current handling in DC-DC input stages.
V_F max	1.3 V @ 1.2A, 25°C - Forward voltage drop directly impacts conduction loss and thermal rise in power path design.
T_J max	175 °C - Maximum junction temperature; enables operation in under-hood automotive environments and sealed industrial enclosures.
R_θJA	86 °C/W - Junction-to-ambient thermal resistance on standard 5mm × 5mm Cu pad; used to calculate steady-state temperature rise.
MSL	Level 1 (per J-STD-020) - No floor life limitation; compatible with standard reflow profiles without baking preconditioning.

Pinout & Package

Package: SOD-123HE - Surface-mount plastic case with matte tin-plated leads, UL 94V-0 molding compound, cathode band polarity marking, and 0.022g mass. Compliant with JESD201 Class 2 whisker testing and J-STD-002 solderability.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to lower-potential side of circuit; requires thermal relief and adequate copper area for heat dissipation.
Cathode	Forward current exit / reverse blocking terminal	Marked by visible band; ties to higher-potential node; critical for correct orientation in series/parallel configurations.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - required for under-hood and lighting modules.
High surge current capability (50A)	Enables use in input rectification where line transients or capacitor charging surges exceed steady-state current.
Low forward voltage (≤1.3V)	Reduces conduction losses in 12V–48V power rails, improving efficiency and easing thermal management in compact designs.
Moisture Sensitivity Level 1	Eliminates pre-bake requirements before reflow, reducing manufacturing complexity and cost in high-volume SMT lines.
Halogen-free & RoHS compliant	Meets IEC 61249-2-21 and EU RoHS directives - essential for export compliance and end-of-life material restrictions.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STPS1L60S	1A, 600V Schottky; lower V_F (~0.7V) but higher I_R (100µA @ 25°C); no AEC-Q101 qualification.	Preferred where ultra-low conduction loss is critical and automotive qualification is not required.	Select STPS1L60S only if system-level reliability testing replaces AEC-Q101 validation.
ON Semi MUR1060	1A, 600V ultrafast recovery; 50ns t_rr; TO-220AC package; higher thermal mass but through-hole mounting.	Suitable for prototyping or low-volume industrial supplies where layout flexibility outweighs SMT automation needs.	Choose MUR1060 when board space permits larger footprint and thermal design leverages case-to-heatsink conduction.

Compared with STPS1L60S and MUR1060, the S1JLSH uniquely combines AEC-Q101 qualification, SOD-123HE SMT compatibility, and 1.2A/600V rating - making it optimal for production automotive and high-density industrial power supplies where reliability, manufacturability, and thermal efficiency are jointly constrained.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for the S1JLSH?

The S1JLSH has a maximum repetitive peak reverse voltage (V_RRM) of 600 V. This rating is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version A2103). The S1JLSH is part of the S1DLSH–S1MLSH series, where the 'J' in the marking code corresponds to the 600V grade. This value defines the highest continuous reverse voltage the diode can block without breakdown under normal operating conditions.

Is the S1JLSH suitable for automotive applications?

Yes, the S1JLSH is explicitly qualified to AEC-Q101 standards, as stated in the FEATURES section of the Taiwan Semiconductor datasheet. This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD), confirming its suitability for automotive under-hood and lighting applications. The S1JLSH also meets MSL Level 1 and halogen-free requirements per IEC 61249-2-21 - all critical for automotive supply chain compliance.

What is the forward voltage (V_F) specification for the S1JLSH at rated current?

The S1JLSH has a maximum forward voltage (V_F) of 1.3 V at 1.2 A and 25°C junction temperature, per the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) to minimize self-heating effects. At elevated temperatures (e.g., 125°C), V_F decreases slightly due to the negative temperature coefficient of silicon PN junctions, but the 1.3 V limit remains the design-critical worst-case conduction loss parameter.

What package type does the S1JLSH use, and what are its key mechanical properties?

The S1JLSH uses the SOD-123HE surface-mount package. Key mechanical properties include matte tin-plated leads (solderable per J-STD-002), UL 94V-0 flammability-rated molding compound, cathode band polarity marking, and a mass of approximately 0.022 g. It meets JESD201 Class 2 whisker resistance and is rated MSL Level 1 - meaning it may be stored indefinitely before reflow without baking.

Does the S1JLSH have a specified thermal resistance, and how is it measured?

Yes, the S1JLSH specifies three thermal resistances: R_θJL = 46°C/W (junction-to-lead), R_θJC = 50°C/W (junction-to-case), and R_θJA = 86°C/W (junction-to-ambient). These values are measured with the device mounted on a standardized 5 mm × 5 mm copper pad test board, per JEDEC JESD51-2 and JESD51-14 guidelines. R_θJA is the most commonly used for PCB-level thermal estimation in typical SMT layouts.
