Product details

Overview

RS2D-E3/5BT from Vishay General Semiconductor is a surface-mount fast switching rectifier diode in SMB (DO-214AA) package, rated for 200 V repetitive peak reverse voltage (V_RRM), 1.5 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 automotive systems.

For engineers reviewing the RS2D-E3/5BT datasheet, RS2D-E3/5BT pinout, RS2D-E3/5BT application, or RS2D-E3/5BT equivalent, key selection criteria include its 200 V V_RRM, low 1.3 V forward voltage at 1.5 A, AEC-Q101 qualification eligibility (via HE3 suffix), 50 A surge rating, and SMB package compatibility with automated SMT placement.

Technical Context

This device is a single silicon PN junction diode with glass-passivated chip construction, optimized for fast recovery (150 ns) to minimize switching losses in high-frequency power conversion topologies. Its thermal resistance (R_θJA = 55 °C/W) and 150 °C maximum junction temperature support operation under sustained load in compact PCB layouts.

The SMB package features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, MSL Level 1 per J-STD-020, and UL 94 V-0 molding compound. Polarity is marked by a cathode band; the anode and cathode terminals are unidirectional and non-reversible.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	200 V - supports input rectification up to 200 V DC blocking in offline or intermediate bus applications
I_F(AV)	1.5 A at T_L = 100 °C - enables continuous conduction mode operation in mid-power SMPS outputs
t_rr	150 ns - reduces reverse recovery loss and EMI in 100–500 kHz switching converters
V_F	1.3 V at I_F = 1.5 A - limits conduction loss to ~1.95 W, aiding thermal management in dense layouts
I_FSM	50 A (8.3 ms half-sine) - withstands inrush and transient surges without failure
T_J(max)	150 °C - allows operation in under-hood automotive environments or sealed industrial enclosures
C_J	17 pF at 4.0 V, 1 MHz - minimizes capacitive coupling noise in high-dv/dt gate-drive or snubber circuits

Pinout & Package

Package: SMB (DO-214AA), surface-mount, single-diode configuration with cathode band marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H). Mounting pad layout per Vishay spec: 5.59 mm × 2.18 mm minimum footprint.

Pin/Terminal	Circuit Role	Design Meaning
Cathode (banded end)	Output terminal for forward conduction	Connected to positive rail in freewheeling path or output of bridge rectifier; must route with low-inductance trace
Anode (non-banded end)	Input terminal for forward conduction	Connected to switching node (e.g., MOSFET drain) or AC input side; polarity reversal causes open-circuit behavior

Key Features

Feature	Design Value
Fast switching (150 ns t_rr)	Enables efficient operation in 200–500 kHz DC-DC converters without excessive switching loss or ringing
Glass-passivated junction	Ensures long-term reliability and moisture resistance in humid or thermally cycled environments
MSL Level 1 (260 °C peak)	Supports standard lead-free reflow profiles without popcorn or delamination risk
AEC-Q101 qualification path	HE3-suffix variants available for automotive-grade production; RS2D-E3/5BT is commercial-grade baseline
SMB package with solderable matte tin leads	Compatible with J-STD-002 wetting balance and JESD 22-B102 solderability testing for high-yield assembly

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH2R02U (STMicroelectronics)	Same SMB package, 200 V V_RRM, but 1.7 V V_F at 1.5 A and 200 ns t_rr	Higher conduction loss and slower recovery increase heat and EMI in >250 kHz designs	Prefer RS2D-E3/5BT where efficiency or frequency >300 kHz is critical
SS22 (ON Semiconductor)	Schottky diode, 20 V V_RRM, 2 A I_F(AV), 0.5 V V_F, no reverse recovery	Not suitable for 200 V applications; limited to low-voltage DC-DC outputs	Select RS2D-E3/5BT for 200 V blocking; SS22 only for ≤20 V secondary-side use

Compared with STTH2R02U, RS2D-E3/5BT delivers lower forward loss and faster recovery for higher-frequency converters; versus SS22, it provides essential 200 V capability at the cost of higher V_F, making it the appropriate choice for intermediate bus and offline rectification where voltage rating is primary.

FAQ

What is the maximum junction temperature rating for RS2D-E3/5BT?

The RS2D-E3/5BT has a maximum junction temperature (T_J(max)) of +150 °C, verified per Vishay Document Number 88708. This rating enables reliable operation in high-ambient environments such as automotive engine bays or sealed industrial enclosures. Derating curves confirm 1.5 A I_F(AV) is maintained up to 100 °C lead temperature, and thermal resistance R_θJA is 55 °C/W on standard 7.0 mm × 7.0 mm copper pads. The RS2D-E3/5BT must be thermally anchored per recommended pad layout to sustain this rating.

Is RS2D-E3/5BT AEC-Q101 qualified?

No, RS2D-E3/5BT is the commercial-grade version with RoHS-compliant E3 suffix. AEC-Q101 qualification is available only for variants with HE3 suffix (e.g., RS2DHE3_A/I), which undergo additional stress testing per automotive requirements. The RS2D-E3/5BT datasheet explicitly states AEC-Q101 qualification applies "base P/NHE3", not E3. For automotive production, specify RS2DHE3_A/I or RS2DHE3_A/H and verify qualification status via Vishay's automotive product portal before design-in.

What does the "5BT" in RS2D-E3/5BT indicate?

The "5BT" in RS2D-E3/5BT is Vishay's package code denoting 13-inch diameter plastic tape and reel packaging with 3200 units per reel. It is distinct from "52T", which indicates 7-inch reels of 750 units. Both share identical electrical and thermal specifications; the difference is purely logistical and affects SMT feeder compatibility and inventory management. The RS2D-E3/5BT is fully interchangeable with RS2D-E3/52T at the component level.

What is the reverse recovery time (t_rr) of RS2D-E3/5BT and how is it measured?

The RS2D-E3/5BT has a maximum reverse recovery time (t_rr) of 150 ns, measured under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A, per Vishay Document Number 88708. This value reflects the time required for minority carriers to clear after forward conduction ceases, directly impacting switching loss and EMI in high-frequency converters. The RS2D-E3/5BT's 150 ns t_rr is confirmed across the full operating temperature range and distinguishes it from slower RS2G (250 ns) and RS2J (500 ns) variants in the same family.

Can RS2D-E3/5BT replace a Schottky diode in a 200 V application?

No-Schottky diodes are inherently limited to ≤200 V breakdown; commercially available Schottky rectifiers rated for 200 V V_RRM do not exist due to material physics constraints. The RS2D-E3/5BT is a PN junction fast recovery diode engineered precisely for 200 V applications where Schottky alternatives are unavailable. While it exhibits higher V_F than Schottkys, its 150 ns t_rr and 200 V rating make RS2D-E3/5BT the technically appropriate solution for this voltage class, unlike any Schottky part.
