Product details
Overview
RS2JH from Taiwan Semiconductor is a 2 A, 600 V fast recovery surface-mount rectifier in DO-214AA (SMB) package, featuring 250 ns reverse recovery time, 1.3 V max forward voltage at 2 A, and AEC-Q101 qualification for automotive-grade reliability in freewheeling and snubber circuits.
For engineers reviewing the RS2JH datasheet, RS2JH pinout, RS2JH application, or RS2JH equivalent, key selection criteria include its 600 V repetitive peak reverse voltage, 50 A surge rating, 175 °C max junction temperature, moisture sensitivity level 1 compliance, and suitability for DC-DC converters and automotive lighting systems.
Technical Context
The RS2JH is a single-die, glass-passivated silicon junction rectifier optimized for fast switching with low conduction and switching losses. Its 250 ns trr and 50 pF junction capacitance support high-frequency operation in flyback and boost topologies.
Designed for automotive environments, it meets AEC-Q101 stress test requirements including temperature cycling, HTRB, and ESD, and operates across –55 °C to +175 °C junction range with 55 °C/W junction-to-ambient thermal resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse blocking voltage before breakdown |
| IF | 2 A - continuous average forward current at TL = 75 °C |
| IFSM | 50 A - non-repetitive surge current (8.3 ms half-sine), enabling robust transient handling |
| trr | 250 ns - reverse recovery time at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A, critical for minimizing switching loss |
| VF | ≤1.3 V - max forward voltage drop at IF = 2 A, TJ = 25 °C, defining conduction loss |
| TJ max | +175 °C - maximum operating junction temperature, supporting under-hood automotive use |
| RθJA | 55 °C/W - thermal resistance from junction to ambient, used to calculate temperature rise on PCB |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R06 | Same 600 V VRRM, 2 A IF, but 125 ns trr; TO-220AC package, higher thermal mass | Preferred in higher-power, heatsink-mounted designs; not surface-mount compatible | Select STTH2R06 only if board space allows through-hole mounting and faster recovery is prioritized over footprint |
| ON Semi MUR260 | 600 V VRRM, 2 A IF, 75 ns trr; DO-204AL (DO-41) axial lead, no AEC-Q101 qualification | Suitable for industrial non-automotive applications; lacks automotive reliability validation | Choose MUR260 for cost-sensitive consumer or industrial designs where AEC-Q101 is not required |
Compared with STTH2R06 and MUR260, the RS2JH uniquely combines AEC-Q101 qualification, SMB surface-mount form factor, and 250 ns recovery-making it optimal for space-constrained, thermally demanding automotive modules where reliability and manufacturability are jointly critical.

FAQ
What is the maximum junction temperature rating for RS2JH?
The RS2JH has a maximum junction temperature (TJ) rating of +175 °C, verified per AEC-Q101 test conditions. This enables reliable operation in under-hood automotive environments and high-temperature industrial power supplies. The RS2JH maintains specified electrical performance up to this limit when thermal design accounts for its 55 °C/W RθJA.
Is RS2JH qualified for automotive applications?
Yes, RS2JH is AEC-Q101 qualified, meaning it has passed all stress tests required for discrete semiconductors in automotive electronics-including temperature cycling, high-temperature reverse bias, and electrostatic discharge. This qualification is explicitly stated in the official Taiwan Semiconductor datasheet revision B2304 for RS2JH.
What is the reverse recovery time (trr) of RS2JH and how is it measured?
The RS2JH 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 the datasheet. This value reflects the time required for minority carriers to clear after forward conduction, directly impacting switching loss in high-frequency power stages using the RS2JH.
Does RS2JH have moisture sensitivity level (MSL) certification?
Yes, RS2JH is rated MSL Level 1 per J-STD-020, meaning it can be stored indefinitely at ≤30 °C/85 % RH and assembled using standard reflow profiles without pre-baking. This simplifies manufacturing logistics and eliminates dry-pack requirements for the RS2JH in automated SMT lines.
What packaging and reel quantity is available for RS2JH?
RS2JH is supplied in DO-214AA (SMB) package on 3,000-piece tape-and-reel format, compatible with standard pick-and-place equipment. The marking code "RS2J" appears on the cathode-banded surface, and the device uses matte tin-plated leads solderable per J-STD-002-ensuring consistent assembly yield for the RS2JH.
