Product details
Overview
RS2JAH from Taiwan Semiconductor is a 600 V, 1.5 A fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 250 ns reverse recovery time, 1.3 V max forward voltage at 1.5 A, and AEC-Q101 qualification for automotive-grade reliability. It serves as a primary output rectifier in DC/DC converters and snubber circuits.
For engineers reviewing the RS2JAH datasheet, RS2JAH pinout, RS2JAH application, or RS2JAH equivalent, key selection criteria include its 600 V repetitive peak reverse voltage, 50 A surge rating, glass-passivated junction, moisture sensitivity level 1, and compatibility with automated SMT placement in automotive lighting and power conversion systems.
Technical Context
The RS2JAH employs a single-die silicon PN junction with glass passivation to ensure stable operation across –55 °C to +175 °C junction temperature range. Its fast recovery performance (trr = 250 ns) enables high-frequency switching in flyback and forward converters without excessive switching loss.
Thermal design is supported by RθJL = 18 °C/W and RθJA = 55 °C/W, enabling reliable 1.5 A continuous conduction in standard PCB layouts. The cathode-band polarity marking and matte tin-plated leads comply with J-STD-002 solderability and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - Maximum non-repetitive reverse blocking voltage; defines safe operating margin in 400–500 V DC bus applications |
| IF | 1.5 A - Continuous average forward current at TL = 75 °C; sets thermal derating baseline for PCB copper area design |
| trr | 250 ns - Measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables >100 kHz switching with low recovery loss |
| VF (max) | 1.3 V - At IF = 1.5 A, TJ = 25 °C; determines conduction loss and thermal rise in high-duty-cycle operation |
| IFSM | 50 A - 8.3 ms half-sine surge rating; supports inrush and fault-current handling in automotive power modules |
| TJ (max) | +175 °C - Maximum junction temperature; allows operation in under-hood environments without forced cooling |
| CJ | 50 pF - At 1 MHz, VR = 4.0 V; impacts EMI filtering and snubber sizing in high-dv/dt circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L60 | 600 V, 1 A, trr = 110 ns, TO-277 package | Lower current rating; requires layout change due to different footprint and thermal pad | Preferred where ultra-fast recovery dominates over current capacity and board space permits rework |
| ON Semi MUR160 | 600 V, 1 A, trr = 50 ns, DO-41 through-hole | Through-hole mounting; not suitable for automated SMT; higher surge rating but lower average current | Only viable for prototyping or low-volume through-hole builds; not recommended for production SMT lines |
Compared with STTH1L60 and MUR160, the RS2JAH uniquely balances 1.5 A current capability, 250 ns recovery, AEC-Q101 qualification, and DO-214AC SMT compatibility-making it optimal for automotive and industrial DC/DC converters requiring both robustness and manufacturability.

FAQ
What is the maximum junction temperature rating for RS2JAH?
The RS2JAH has a maximum junction temperature (TJ) rating of +175 °C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet Version B2304. This allows the RS2JAH to operate reliably in under-hood automotive environments and high-ambient industrial settings without derating below rated current at board-level temperatures up to 125 °C.
Is RS2JAH AEC-Q101 qualified?
Yes, RS2JAH is explicitly AEC-Q101 qualified as stated in the FEATURES section of the Taiwan Semiconductor datasheet. This qualification covers stress tests including HTSL, TC, UHAST, and mechanical shock, confirming suitability for automotive power electronics such as lighting and body control modules where RS2JAH is deployed.
What does the marking code 'RS2JA' on the RS2JAH device indicate?
The marking code 'RS2JA' on the RS2JAH device identifies it as the 600 V variant within the RS2xAH family, per the ORDERING INFORMATION table. 'RS2' denotes the series, 'J' corresponds to 600 V VRRM, and 'A' indicates the standard version-distinct from RS2KAH (800 V) and RS2MAH (1000 V). The full orderable part remains RS2JAH.
What is the reverse recovery time (trr) of RS2JAH and how is it measured?
The RS2JAH has a reverse recovery time (trr) of 250 ns, measured under conditions IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, as specified in the ELECTRICAL SPECIFICATIONS table. This value reflects the time required for minority carriers to clear after forward conduction, directly impacting switching loss in high-frequency DC/DC converters where RS2JAH is commonly used.
Does RS2JAH have moisture sensitivity level (MSL) certification?
Yes, RS2JAH is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and requires no baking prior to reflow soldering. This is confirmed in the FEATURES list and supports seamless integration into high-throughput SMT lines without special handling-critical for automotive manufacturing where RS2JAH is widely adopted.
