Product details

Overview

RS1DHE3_A/H from Vishay General Semiconductor is a surface-mount fast switching rectifier diode in SMA (DO-214AC) package, rated for 200 V repetitive peak reverse voltage (V_RRM), 1.0 A average forward current (I_F(AV)), and 150 ns reverse recovery time (t_rr). It serves as a freewheeling or output rectifier in DC/DC converters and AC/DC power supplies for automotive and industrial applications.

For engineers reviewing the RS1DHE3_A/H datasheet, RS1DHE3_A/H pinout, RS1DHE3_A/H application, or RS1DHE3_A/H equivalent, key selection criteria include its AEC-Q101 qualification, 30 A surge capability (I_FSM), low 1.3 V forward voltage at 1.0 A, and MSL Level 1 moisture sensitivity rating compatible with standard reflow profiles.

Technical Context

The RS1DHE3_A/H implements a single silicon PN junction with glass passivated pellet construction, enabling fast recovery (150 ns) and stable operation up to 150 °C junction temperature. Its low-profile SMA package supports automated placement and meets UL 94 V-0 flammability requirements.

Designed for high-efficiency switching topologies, it delivers 5.0 μA maximum reverse leakage at 25 °C and 50 μA at 125 °C under rated blocking voltage, with typical junction capacitance of 7.0 pF at 4.0 V and 1 MHz - optimized for reduced switching loss in 100–500 kHz power stages.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - supports input rectification in 120 VAC-derived supplies and 24 VDC bus protection
I_F(AV)	1.0 A at T_L = 90 °C - suitable for continuous conduction mode in sub-10 W SMPS outputs
t_rr	150 ns - enables efficient operation in 200–500 kHz flyback and buck converters
V_F	1.3 V at I_F = 1.0 A - limits conduction loss to ≤1.3 W at full load, aiding thermal management
I_FSM	30 A (8.3 ms half-sine) - withstands inrush and transient surges in automotive cold-crank conditions
T_J max.	150 °C - allows operation in under-hood environments without derating below 90 °C ambient

Equivalent & Alternatives

The following parts are listed as comparable options for similar fast switching rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
RS1D-E3/61T	Same electrical specs, but commercial-grade (non-AEC-Q101); MSL Level 1, RoHS-compliant	Not qualified for automotive; suitable for consumer/industrial where qualification not required	Select when AEC-Q101 is unnecessary and cost optimization is prioritized
SB120-E3/52T	1.0 A, 200 V Schottky; V_F ≈ 0.85 V; t_rr not applicable; higher leakage (~200 μA @ 125 °C)	Better efficiency at light loads; unsuitable for high-temp reverse-bias hold	Choose for lower conduction loss where reverse leakage and temperature stability are less critical

Compared with RS1D-E3/61T, RS1DHE3_A/H adds automotive qualification and tighter process control; versus SB120-E3/52T, it trades higher V_F for superior high-temperature reverse blocking and lower leakage - critical in thermally constrained or automotive environments.

FAQ

What is the maximum junction temperature rating for RS1DHE3_A/H?

The RS1DHE3_A/H has a maximum junction temperature (T_J) of +150 °C, verified per Vishay's thermal characterization and qualified for continuous operation at this limit when mounted on PCB copper pads per JEDEC standards. This rating enables use in under-hood automotive locations and sealed industrial enclosures where ambient temperatures exceed 100 °C. The RS1DHE3_A/H maintains specified electrical parameters up to this temperature.

Is RS1DHE3_A/H pin-compatible with other RS1x series diodes?

Yes, all RS1x devices - including RS1DHE3_A/H - share identical SMA (DO-214AC) package dimensions, anode/cathode pinout, and mounting pad layout. This allows direct substitution among RS1A through RS1K variants without PCB redesign, provided voltage, current, and recovery time requirements are met. The RS1DHE3_A/H specifically matches RS1D-E3/61T mechanically and electrically except for AEC-Q101 qualification.

Does RS1DHE3_A/H meet automotive reliability standards?

Yes, RS1DHE3_A/H is AEC-Q101 qualified, meaning it has passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and unbiased highly accelerated stress testing (uHAST). This qualification confirms suitability for automotive applications such as body control modules and infotainment power supplies. The "HE3" suffix explicitly denotes AEC-Q101 compliance per Vishay's ordering nomenclature.

What is the reverse recovery time (t_rr) of RS1DHE3_A/H and how is it measured?

The RS1DHE3_A/H has a maximum reverse recovery time (t_rr) of 150 ns, measured under standardized conditions: I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This value reflects the diode's speed in transitioning from forward conduction to reverse blocking, directly impacting switching losses in high-frequency converters. The RS1DHE3_A/H achieves this performance via optimized doping and junction geometry within its glass-passivated silicon die.

Can RS1DHE3_A/H be used in lead-free reflow processes?

Yes, RS1DHE3_A/H is rated MSL Level 1 per J-STD-020 and supports peak reflow temperatures up to 260 °C, fully compatible with standard lead-free soldering profiles. Its matte tin-plated leads comply with J-STD-002 and JESD22-B102 for solderability, and whisker resistance is certified to JESD201 Class 2. No pre-baking is required prior to assembly, simplifying manufacturing flow for the RS1DHE3_A/H.
