Product details
Overview
RS1JLH from Taiwan Semiconductor is a fast recovery surface mount rectifier with 600 V repetitive peak reverse voltage (VRRM), 0.8 A average forward current (IF), and 250 ns reverse recovery time (trr), designed for snubber and freewheeling roles in automotive DC-DC converters and car lighting circuits.
For engineers reviewing the RS1JLH datasheet, RS1JLH pinout, RS1JLH application, or RS1JLH equivalent, key selection criteria include its AEC-Q101 qualification, Sub SMA package compatibility with automated placement, glass-passivated junction, and 150 °C maximum junction temperature under continuous operation.
Technical Context
The RS1JLH is a single-die, unidirectional silicon rectifier optimized for high-efficiency switching in medium-voltage power conversion. Its fast recovery (250 ns) and low junction capacitance (10 pF at 4 V) reduce switching losses and EMI generation during turn-off transitions.
Thermally, it features a junction-to-lead resistance of 32 °C/W and junction-to-ambient resistance of 105 °C/W, enabling reliable operation up to 150 °C junction temperature. The device uses matte tin-plated leads compliant with J-STD-002 solderability and meets JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports input rails up to 420 V RMS in bridge or clamp configurations |
| IF | 0.8 A - continuous forward current rating at TA = 75 °C with derating above |
| trr | 250 ns - enables operation in 100–500 kHz switching topologies with low recovery loss |
| VF | ≤1.3 V @ 0.8 A, 25 °C - limits conduction loss to ≤1.04 W at rated DC load |
| IR | ≤5 µA @ 25 °C, ≤50 µA @ 125 °C - ensures minimal leakage in high-impedance hold or sensing paths |
| RθJL | 32 °C/W - allows direct thermal coupling to PCB copper for passive cooling without heatsink |
Pinout & Package
Package: Sub SMA - surface-mount plastic case with cathode band polarity marking, UL 94V-0 molding compound, and 0.019 g mass. Compatible with standard SMA footprint but with reduced body height and lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck freewheel path) |
| Cathode | Forward current exit / reverse blocking terminal | Marked by visible band; ties to output rail or energy return path |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per stress test plan |
| Glass passivated junction | Prevents moisture ingress and surface contamination, improving long-term reverse leakage stability |
| Moisture sensitivity level 1 | Zero floor life limitation - no baking required prior to reflow assembly |
| Halogen-free construction | Complies with IEC 61249-2-21, supporting RoHS and ELV compliance in vehicle ECUs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06U | VRRM = 600 V, IF = 1.0 A, trr = 75 ns, TO-277 package | Higher IF and faster trr, but larger footprint and non-AEC-Q101 rated | Preferred where higher current or tighter timing is needed and automotive qualification is not mandatory |
| ES1J | VRRM = 600 V, IF = 1.0 A, trr = 35 ns, SMA package | Lower trr and higher IF, but not AEC-Q101 qualified and no halogen-free certification | Suitable for cost-sensitive industrial DC-DC where qualification and environmental specs are secondary |
Compared with STTH1R06U and ES1J, the RS1JLH trades some speed and current headroom for automotive-grade reliability, moisture insensitivity, and halogen-free compliance-making it the preferred choice for production automotive modules requiring full PPAP support.

FAQ
What is the maximum junction temperature rating for RS1JLH?
The RS1JLH has a maximum junction temperature (TJ) rating of +150 °C, verified per absolute maximum ratings table. This allows continuous operation in under-hood environments when mounted on thermally enhanced PCBs. Derating begins above 75 °C ambient, and the device maintains specified VF and IR performance up to TJ = 150 °C as confirmed in electrical specifications.
Is RS1JLH suitable for automotive applications requiring AEC-Q101 qualification?
Yes, RS1JLH is explicitly AEC-Q101 qualified per the manufacturer's documentation. It undergoes stress testing including high-temperature reverse bias (HTRB), temperature cycling, and unbiased highly accelerated stress testing (uHAST) to meet automotive reliability requirements. This makes RS1JLH appropriate for use in engine control units, lighting modules, and ADAS power supplies.
What does the 'J' in RS1JLH indicate?
The 'J' in RS1JLH designates the 600 V repetitive peak reverse voltage (VRRM) rating within the RS1xLH family. Per the ordering matrix, RS1ALH = 50 V, RS1BLH = 100 V, RS1DLH = 200 V, RS1GLH = 400 V, RS1JLH = 600 V, RS1KLH = 800 V, and RS1MLH = 1000 V. The marking code on the device is RJL.
What is the reverse recovery time (trr) of RS1JLH and how is it measured?
The RS1JLH has a reverse recovery time (trr) of 250 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per JEDEC standards. This value is confirmed in the electrical specifications table and applies specifically to RS1JLH-not the entire RS1xLH series. Faster variants (e.g., RS1GLH) have trr = 150 ns; slower ones (RS1KLH/MLH) reach 500 ns.
Does RS1JLH require moisture sensitivity handling before reflow soldering?
No, RS1JLH is rated at Moisture Sensitivity Level (MSL) 1 per J-STD-020, meaning it has unlimited floor life and does not require dry pack storage or baking prior to reflow. This simplifies manufacturing logistics and eliminates moisture-related popcorning risk during lead-free reflow profiles.
