Product details
Overview
RS3JH from Taiwan Semiconductor is a 600 V, 3 A fast recovery surface-mount rectifier in DO-214AB (SMC) package, featuring 250 ns reverse recovery time, 100 A peak surge current, and AEC-Q101 qualification for automotive-grade reliability-used in DC-DC converters and snubber circuits.
For engineers reviewing the RS3JH datasheet, RS3JH pinout, RS3JH application, or RS3JH equivalent, key selection criteria include repetitive peak reverse voltage (600 V), forward voltage at 3 A (≤1.3 V), junction temperature range (–55°C to +175°C), thermal resistance (RθJL = 15°C/W), and moisture sensitivity level (J-STD-020 Level 1).
Technical Context
The RS3JH is a single-die, glass-passivated fast recovery rectifier optimized for high-efficiency switching applications. Its 250 ns reverse recovery time and low forward voltage support reduced switching losses in medium-voltage power conversion stages.
Designed for automotive and industrial environments, it meets AEC-Q101 stress testing requirements and features matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S (STMicroelectronics) | Same VRRM (600 V), identical DO-214AB package, but trr = 150 ns (faster), VF = 1.25 V typ @ 3 A | Better suited for higher-frequency (>300 kHz) designs where lower recovery loss is critical | Prefer STTH3L06S when optimizing for minimal switching loss; RS3JH remains preferred for cost-sensitive AEC-Q101-compliant automotive use. |
| ES3J (ON Semiconductor) | VRRM = 600 V, DO-214AB, trr = 35 ns (much faster), but not AEC-Q101 qualified and TJ max = +150°C | Applicable in commercial/industrial SMPS but not certified for automotive under-hood deployment | Select ES3J only for non-automotive applications requiring ultra-fast recovery; RS3JH provides validated automotive reliability. |
Compared with STTH3L06S and ES3J, the RS3JH trades marginal speed for AEC-Q101 qualification, extended +175°C operation, and tighter process control-making it the preferred choice for automotive power conversion where long-term field reliability outweighs nanosecond-level trr gains.

FAQ
What is the maximum repetitive peak reverse voltage rating for RS3JH?
The RS3JH has a maximum repetitive peak reverse voltage (VRRM) of 600 V, verified per datasheet Section "Absolute Maximum Ratings." This rating defines the highest reverse voltage the device can block repeatedly without breakdown at TJ ≤ +175°C. Derating is required above 25°C ambient per the forward current derating curve in the RS3JH datasheet.
Is RS3JH qualified for automotive applications?
Yes, RS3JH is AEC-Q101 qualified, meaning it has passed stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing (uHAST). This qualification confirms suitability for automotive power electronics such as body control modules and lighting drivers, as documented in Taiwan Semiconductor's RS3JH product release version B2304.
What is the reverse recovery time (trr) of RS3JH and how is it measured?
The RS3JH reverse recovery time is 250 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the test circuit in Figure 6 of the RS3JH datasheet. This value reflects the time required for minority carriers to clear after forward conduction, directly impacting switching loss in high-frequency converters.
Does RS3JH have a halogen-free and RoHS-compliant construction?
Yes, RS3JH uses halogen-free molding compound and matte tin-plated leads, fully complying with RoHS Directive 2011/65/EU and JEDEC JS709E halogen content limits. This is explicitly stated in the "Features" section of the RS3JH datasheet and confirmed in the "Ordering Information" page.
What is the thermal resistance from junction to lead (RθJL) for RS3JH?
The junction-to-lead thermal resistance (RθJL) of RS3JH is 15°C/W, as specified in the "Thermal Performance" table of the datasheet. This parameter enables accurate thermal modeling when mounting the DO-214AB package directly to a large copper pour, supporting reliable operation at full 3 A current with proper PCB layout.
