Product details

Overview

RS1D-E3/5AT 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 consumer and industrial applications.

For engineers reviewing the RS1D-E3/5AT datasheet, RS1D-E3/5AT pinout, RS1D-E3/5AT application, or RS1D-E3/5AT equivalent, key selection criteria include its 200 V V_RRM, 1.3 V forward voltage at 1.0 A, 30 A non-repetitive surge rating, AEC-Q101 qualification eligibility via HE3 suffix variants, and compatibility with automated SMT placement on standard PCB copper pads.

Technical Context

This device implements a single silicon PN junction with glass-passivated chip construction, enabling fast recovery (150 ns) and stable operation up to 150 °C junction temperature. Its low thermal resistance (R_θJL = 32 °C/W) supports high-power-density layouts when mounted on 5.0 mm × 5.0 mm copper pads.

The RS1D-E3/5AT operates as a unidirectional current path with cathode marked by a band; it delivers predictable forward conduction and minimal reverse leakage (5.0 μA at 25 °C, 50 μA at 125 °C) under rated blocking conditions, making it suitable for high-efficiency flyback and buck converter outputs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - maximum repetitive reverse voltage the diode blocks without breakdown; defines usable input/output voltage range in rectification stages
I_F(AV)	1.0 A at T_L = 90 °C - continuous forward current capability with standard PCB thermal relief; sets minimum trace width and pad size requirements
t_rr	150 ns - measured at I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A; enables >100 kHz switching in SMPS without excessive switching loss
V_F	1.3 V at I_F = 1.0 A - forward voltage drop directly impacts conduction loss and thermal design in high-duty-cycle applications
I_FSM	30 A - peak non-repetitive surge current (8.3 ms half-sine); withstands inrush and transient overloads in power supply startup
T_J max.	150 °C - maximum allowable junction temperature; determines derating curve slope and heatsinking necessity
C_J	7.0 pF at 4.0 V, 1 MHz - junction capacitance affects high-frequency noise coupling and snubber design in fast-switching topologies

Pinout & Package

Package: SMA (DO-214AC), surface-mount, low-profile plastic case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode indicated by color band.

Cathode	Forward current exit point	Connected to higher-potential side (e.g., output rail, ground return path); marked by visible band

Key Features

Feature	Design Value
Fast switching recovery	150 ns t_rr minimizes reverse recovery charge (Q_rr) and associated losses in high-frequency converters

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1R02U	200 V V_RRM, 1.0 A I_F(AV), 120 ns t_rr, TO-277 package (single-die, no leads)	Lower profile (1.1 mm), but requires different footprint and stencil design; no leaded option for wave soldering	Select when board space is critical and reflow-only assembly is used; verify thermal performance on 2-layer PCBs
ON Semi MUR120	200 V V_RRM, 1.0 A I_F(AV), 35 ns t_rr, DO-41 through-hole package	Ultra-fast recovery but incompatible with SMT lines; requires manual or wave soldering	Choose only for legacy through-hole designs or prototyping where hand-soldering is acceptable

Compared with STTH1R02U and MUR120, RS1D-E3/5AT offers standardized SMA footprint, MSL Level 1 reflow compatibility, and balanced trade-off between speed (150 ns), robustness (30 A I_FSM), and manufacturability-making it optimal for high-volume SMT production of mid-frequency power supplies.

FAQ

What is the maximum junction temperature rating for RS1D-E3/5AT?

The RS1D-E3/5AT has a maximum junction temperature (T_J) of 150 °C, verified per Vishay Document Number 88707. This rating allows operation in high-ambient environments such as enclosed power adapters or under-hood automotive locations. Derating begins at T_L = 90 °C per the forward current derating curve, and thermal design must ensure R_θJA ≤ 105 °C/W with standard 5.0 mm × 5.0 mm copper pads.

Is RS1D-E3/5AT RoHS-compliant and halogen-free?

Yes, RS1D-E3/5AT carries the "E3" suffix, indicating RoHS-compliance per EU Directive 2011/65/EU and material categorization per Vishay Doc. #99912. It is not halogen-free; for halogen-free and RoHS-compliant versions, specify RS1D-M3/5AT. Both E3 and M3 meet JESD 201 Class 2 whisker test requirements.

Does RS1D-E3/5AT have AEC-Q101 qualification?

RS1D-E3/5AT itself is commercial-grade; however, the identical die and package are used in AEC-Q101-qualified variants RS1DHE3_A/I and RS1DHM3_A/I. These share identical electrical specs, thermal characteristics, and mechanical dimensions-enabling qualification reuse and seamless transition for automotive programs requiring PPAP documentation.

What is the reverse recovery time (t_rr) of RS1D-E3/5AT and how is it measured?

The RS1D-E3/5AT has a 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, per Vishay Document 88707. This value reflects the time required for minority carriers to clear after forward conduction, directly impacting switching loss in topologies operating above 100 kHz.

What packaging format does RS1D-E3/5AT ship in?

RS1D-E3/5AT ships in 13-inch diameter plastic tape and reel, with a base quantity of 7500 units per reel (package code "5AT"). The tape complies with EIA-481-D standards and is compatible with all major SMT pick-and-place equipment. Reel tension and pocket depth are optimized for high-speed placement of SMA (DO-214AC) devices without damage or misfeed.
