Product details
Overview
RS1JAL from Taiwan Semiconductor is a 1A, 600V fast recovery surface-mount rectifier diode in Thin SMA package, featuring 250 ns reverse recovery time, 0.97 V forward voltage at 1.0 A/25°C, and 175°C maximum junction temperature - used in DC-DC converters and switching-mode inverters.
For engineers reviewing the RS1JAL datasheet, RS1JAL pinout, RS1JAL application, or RS1JAL equivalent, key selection criteria include VRRM=600V, trr=250ns, VF=0.97V@1A, thermal resistance RθJL=19°C/W, and Thin SMA package compatibility with automated SMT assembly.
Technical Context
The RS1JAL operates as a single-die, unidirectional fast recovery rectifier optimized for high-frequency switching power supplies. Its glass-passivated junction ensures stable leakage performance up to 125°C (IR ≤ 33 µA), and its low-profile Thin SMA package supports high-density PCB layouts.
Thermal design is enabled by validated RθJL = 19°C/W and RθJA = 81°C/W on a 5 mm × 5 mm Cu pad, while the cathode-band polarity marking and JESD201 Class 2 whisker-resistant matte tin leads ensure manufacturability and reliability in industrial environments.

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, trr = 150 ns, VF = 1.05 V @ 1A, TO-277 package | Lower trr but higher VF and larger footprint; requires different pad layout | Preferred where faster recovery outweighs VF penalty and board space allows TO-277 |
| MBR160 | VRRM = 60 V, VF = 0.55 V @ 1A, Schottky, SMA package | Not suitable for 600 V circuits; only applicable in low-voltage (<100 V) high-efficiency designs | Select only for sub-100 V applications where ultra-low VF justifies voltage limitation |
Compared with STTH1R06U and MBR160, the RS1JAL uniquely balances 600 V rating, 250 ns trr, and Thin SMA compatibility - making it optimal for space-constrained, medium-voltage industrial SMPS where thermal resistance and manufacturability are prioritized over marginal trr reduction or Schottky-level VF.

FAQ
What is the peak repetitive reverse voltage rating for RS1JAL?
The RS1JAL has a peak repetitive reverse voltage (VRRM) rating of 600 V, verified per Taiwan Semiconductor's C2304 datasheet. This defines the maximum reverse-biased voltage the device can block repeatedly without breakdown under normal operating conditions. The RS1JAL must not be operated beyond this rating in continuous or transient conditions unless derated per thermal and surge guidelines.
What is the forward voltage drop of RS1JAL at 1.0 A and 25°C?
The RS1JAL exhibits a typical forward voltage (VF) of 0.97 V at 1.0 A and 25°C, with a maximum of 1.30 V under the same conditions. This value is measured using a pulse test (PW = 0.3 ms) and directly impacts conduction loss and thermal design in power supply applications where the RS1JAL is deployed.
Does RS1JAL have a specified reverse recovery time, and what is its value?
Yes, the RS1JAL has a specified reverse recovery time (trr) of 250 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter is confirmed in the Electrical Specifications table of the official datasheet and reflects the device's suitability for switching frequencies up to ~500 kHz in practical DC-DC converter implementations using RS1JAL.
What package type is used for RS1JAL, and is it RoHS compliant?
The RS1JAL uses the Thin SMA package (JEDEC DO-221AC variation), with matte tin-plated leads and glass passivation. It is RoHS compliant and halogen-free, meeting J-STD-020 moisture sensitivity Level 1. The Thin SMA footprint enables high-density automated placement, and the RS1JAL's marking includes "RS1JAL" and date code per standard TSC labeling.
What is the maximum junction temperature and surge current rating for RS1JAL?
The RS1JAL has a maximum junction temperature (TJ) of +175°C and a non-repetitive surge peak forward current (IFSM) rating of 30 A for 8.3 ms (half-sine wave). These ratings are defined in the Absolute Maximum Ratings table and allow the RS1JAL to withstand short-duration overload events common in industrial power-up sequences and fault conditions.
