Product details
Overview
RS1JLWH from Taiwan Semiconductor is a fast recovery surface-mount rectifier diode with 600 V repetitive peak reverse voltage (VRRM), 1 A average forward current (IF), and 150 ns reverse recovery time (trr) measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A - used in automotive DC-DC converters and snubber circuits.
For engineers reviewing the RS1JLWH datasheet, RS1JLWH pinout, RS1JLWH application, or RS1JLWH equivalent, key selection criteria include its AEC-Q101 qualification, SOD-123W low-profile package, 175 °C max junction temperature, glass-passivated junction, and 1.3 V max forward voltage at 1 A - critical for thermal reliability in space-constrained automotive lighting and power conversion designs.
Technical Context
The RS1JLWH is a single-die, unidirectional fast recovery rectifier optimized for high-efficiency switching applications. Its 150 ns trr enables reduced switching losses in 100–500 kHz DC-DC topologies, while the glass-passivated junction ensures stable leakage performance across -55 °C to +175 °C operating range.
Designed for automated SMT placement, it features matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance. The SOD-123W package delivers 25 °C/W junction-to-lead thermal resistance, supporting sustained 1 A conduction without forced airflow in compact layouts.
Key Specifications

| IF | 1 A continuous - rated for steady-state operation in LED driver and auxiliary supply rails |
| trr | 150 ns - minimizes reverse recovery charge (Qrr) in flyback and boost converters |
| VF max | 1.3 V @ 1 A, 25 °C - limits conduction loss to ≤1.3 W per device at full load |
| IR max | 5 µA @ 600 V, 25 °C - ensures low standby leakage in always-on vehicle modules |
| TJ max | +175 °C - enables under-hood deployment without derating in engine control units |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06S | VRRM = 600 V, trr = 100 ns, VF = 1.15 V @ 1 A - faster but higher cost; TO-277 package | Requires rework of SOD-123W footprint; better for >300 kHz designs needing lower Qrr | Select when trr reduction outweighs board space and procurement complexity |
| ON Semi MUR1060 | VRRM = 600 V, trr = 60 ns, IF = 1 A - ultrafast but SOD-123 package not offered; DO-41/SMA variants only | Not SMD-compatible; incompatible with automated assembly unless using adapter stencil | Choose only for through-hole prototyping or legacy repair where SMT is unavailable |
Compared with STTH1R06S and MUR1060, the RS1JLWH provides optimal balance of AEC-Q101 compliance, SOD-123W manufacturability, and 150 ns trr - making it the preferred choice for production-grade automotive SMT power supplies where footprint, qualification, and thermal robustness are jointly prioritized.

FAQ
What is the maximum repetitive peak reverse voltage rating for RS1JLWH?
The RS1JLWH has a maximum repetitive peak reverse voltage (VRRM) of 600 V, as confirmed in the Absolute Maximum Ratings table on page 1 of the official Taiwan Semiconductor datasheet (Version A2103). This rating applies across the full operating temperature range (-55 °C to +175 °C) and defines the highest reverse-biased voltage the device can block repeatedly without breakdown. It is validated per JEDEC JESD201 and AEC-Q101 stress test protocols.
Is RS1JLWH suitable for automotive applications?
Yes, RS1JLWH is explicitly AEC-Q101 qualified per the manufacturer's documentation, with test reports covering HTOL, temperature cycling, and HTRB. Its SOD-123W package, glass-passivated junction, 175 °C TJ max, and moisture sensitivity level 1 make it approved for under-hood and body-control module use. Taiwan Semiconductor lists "Automotive application" and "Car lighting" as primary applications in the official datasheet.
What is the reverse recovery time (trr) condition for RS1JLWH?
The RS1JLWH reverse recovery time is specified as 150 ns under the exact test conditions: forward current IF = 0.5 A, reverse current IR = 1.0 A, and reverse recovery current Irr = 0.25 A, per the Electrical Specifications table on page 2 of the Taiwan Semiconductor datasheet (Version A2103). This measurement uses a 1.0 MHz square-wave test setup with defined di/dt and dv/dt constraints.
Does RS1JLWH have a halogen-free construction?
Yes, RS1JLWH is halogen-free in accordance with IEC 61249-2-21, as stated in the Features section of the official Taiwan Semiconductor datasheet. The molding compound contains no brominated or chlorinated flame retardants, and all materials meet RoHS Directive 2011/65/EU requirements. Certificate of Compliance is available upon request from authorized distributors.
What is the thermal resistance from junction to ambient (RθJA) for RS1JLWH?
The junction-to-ambient thermal resistance (RθJA) for RS1JLWH is 80 °C/W, measured under standard JEDEC JESD51-2 conditions (single device on 1-inch² FR-4 board with 2 oz copper). This value assumes no additional copper pour or airflow. With 1-inch² thermal pad, actual RθJA improves to ~45 °C/W - enabling full 1 A operation at up to 70 °C ambient without active cooling.
