Product details
Overview
RS1JLSH from Taiwan Semiconductor is a 1.2A, 600V fast recovery surface-mount rectifier in SOD-123HE package, featuring 300ns reverse recovery time, 50A peak surge current, and AEC-Q101 qualification for automotive power conversion circuits such as DC-DC converters and car lighting.
For engineers reviewing the RS1JLSH datasheet, RS1JLSH pinout, RS1JLSH application, or RS1JLSH equivalent, key selection criteria include repetitive peak reverse voltage (600V), forward voltage drop (≤1.3V at 1.2A), junction temperature range (–55°C to +175°C), thermal resistance (RθJA = 80°C/W), and moisture sensitivity level (J-STD-020 Level 1).
Technical Context
This discrete diode operates as a unidirectional, single-die fast recovery rectifier optimized for high-efficiency switching power supplies. Its 300ns trr and low VF support reduced switching losses in high-frequency DC-DC topologies.
The SOD-123HE package enables automated placement and delivers RθJL = 20°C/W for improved thermal transfer to PCB copper. AEC-Q101 qualification confirms suitability for under-hood automotive environments with extended temperature cycling and mechanical stress requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse blocking voltage without breakdown |
| IF | 1.2 A - continuous average forward current at TA = 25°C |
| IFSM | 50 A - non-repetitive surge capability (8.3 ms half-sine) for transient load handling |
| trr | 300 ns - fast reverse recovery minimizes switching loss in SMPS operating up to ~200 kHz |
| TJ max | +175°C - extended junction temperature rating supports high-ambient automotive applications |
| RθJA | 80°C/W - thermal resistance from junction to ambient, measured on standard FR-4 PCB (1 in² copper pad) |
| VF | ≤1.3 V - forward voltage at IF = 1.2A and TJ = 25°C, directly impacts conduction loss |
Pinout & Package
SOD-123HE is a compact, surface-mount plastic package with cathode-indicated polarity via band marking, matte tin-plated leads compliant with J-STD-002 solderability, and UL 94V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of circuit; requires adequate copper area for thermal dissipation |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; connects to higher-potential node; critical for correct orientation in series/parallel configurations |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06S | Same 1.2A/600V rating but TO-277 package; trr = 250ns; RθJA = 65°C/W | Higher thermal performance but larger footprint; not SMD-compatible with SOD-123HE land pattern | Select when board-level thermal management allows larger package and tighter trr is prioritized over size |
| ON Semi MUR106 | 1A/600V; trr = 50ns; DO-41 through-hole; VF = 1.7V @ 1A | Lower current rating and higher VF; incompatible mounting method and thermal profile | Consider only for legacy through-hole designs where ultra-fast trr outweighs efficiency and packaging constraints |
Compared with STTH1L06S and MUR106, RS1JLSH provides optimal balance of compact SOD-123HE packaging, AEC-Q101 compliance, and verified 300ns trr-making it preferred for new automotive SMT designs requiring space efficiency and qualification traceability.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for RS1JLSH?
The RS1JLSH has a VRRM of 600 V, meaning it can reliably block up to 600 volts in reverse bias without breakdown under repetitive conditions. This rating is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version B2304) and applies specifically to the RS1JLSH variant-not the RS1KLSH (800V) or RS1MLSH (1000V) variants in the same family.
Is RS1JLSH qualified for automotive applications?
Yes, RS1JLSH is AEC-Q101 qualified, as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and mechanical shock-validating its use in automotive power systems such as lighting and DC-DC converters where reliability under harsh environmental conditions is critical.
What is the forward voltage (VF) of RS1JLSH at rated current?
The RS1JLSH exhibits a maximum forward voltage of 1.3 V at IF = 1.2 A and TJ = 25°C, per the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and directly determines conduction loss in power stage design-lower VF improves system efficiency and reduces thermal loading on the device.
What package type does RS1JLSH use, and what are its key mechanical attributes?
RS1JLSH uses the SOD-123HE package-a compact, surface-mount plastic case with cathode band marking, matte tin-plated leads compliant with J-STD-002, and UL 94V-0 flammability rating. Its dimensions (e.g., 1.95 mm length, 1.25 mm width) and suggested pad layout are specified in the Package Outline Dimensions drawing (HQ2SD07-SOD123HE-038 REV A).
Does RS1JLSH have moisture sensitivity level (MSL) rating, and what does it mean for assembly?
Yes, RS1JLSH is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and requires no baking prior to reflow soldering. This simplifies manufacturing logistics and eliminates moisture-related popcorning risk-critical for high-yield SMT assembly in automotive electronics production lines.
