Product details
Overview
S2D-E3/5BT from Vishay General Semiconductor is a surface-mount glass passivated silicon rectifier diode in DO-214AA (SMB) package, rated for 200 V repetitive peak reverse voltage (VRRM), 1.5 A average forward current (IF(AV)), and 50 A non-repetitive surge current (IFSM), used as a freewheeling or output rectifier in automotive DC/DC converters.
For engineers reviewing the S2D-E3/5BT datasheet, S2D-E3/5BT pinout, S2D-E3/5BT application, or S2D-E3/5BT equivalent, key selection criteria include its AEC-Q101 qualification, low 1.15 V forward voltage at 1.5 A, 1.0 μA reverse leakage at 200 V, 2.0 μs reverse recovery time, and MSL Level 1 moisture sensitivity rating for high-reliability automotive power stages.
Technical Context
This single-die standard recovery rectifier operates with a maximum junction temperature of 150 °C and exhibits thermal resistance of 53 °C/W (junction-to-ambient) and 16 °C/W (junction-to-lead) when mounted on a PCB with specified copper pad areas. Its glass-passivated junction ensures stable performance under thermal cycling and humidity exposure.
The device features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards, and passes JESD 201 Class 1A whisker testing. Polarity is indicated by a cathode band on the SMB package body.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R02U | 200 V VRRM, 2 A IF(AV), 1.15 V VF, but TO-220AC package (through-hole) | Requires PCB through-hole mounting and larger board area; not suitable for space-constrained SMT designs | Select only if mechanical mounting or thermal mass requirements favor through-hole construction |
| ON Semi MUR220 | 200 V VRRM, 2 A IF(AV), 1.25 V VF, 50 ns trr (ultrafast), DO-214AA package | Ultrafast recovery enables higher-frequency operation (>200 kHz) but increases EMI risk in noise-sensitive analog sections | Prefer for high-frequency SMPS where trr < 50 ns is required; avoid where standard recovery reduces EMI |
Compared with STTH2R02U and MUR220, the S2D-E3/5BT offers optimal balance of AEC-Q101 qualification, SMB footprint compatibility, and standard recovery behavior-making it ideal for cost-sensitive, thermally constrained automotive and industrial rectification where ultrafast switching is unnecessary.

FAQ
What is the maximum junction temperature rating for the S2D-E3/5BT?
The S2D-E3/5BT has a maximum junction temperature (TJ max.) of 150 °C, validated per JEDEC standards. This rating allows reliable operation in under-hood automotive environments and high-temperature industrial enclosures. Derating curves in the Vishay datasheet (Document Number 88712) define allowable current versus ambient temperature, and the S2D-E3/5BT must be thermally managed using recommended PCB copper pad areas to maintain this limit.
Is the S2D-E3/5BT qualified for automotive applications?
Yes, the S2D-E3/5BT is AEC-Q101 qualified, as confirmed in the Vishay datasheet revision 14-Aug-13 (Document Number 88712). This qualification covers stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and highly accelerated stress test (HAST), making the S2D-E3/5BT suitable for use in automotive power modules, body control units, and infotainment systems where reliability under thermal and mechanical stress is critical.
What does the "E3/5BT" suffix indicate in S2D-E3/5BT?
The "E3" suffix denotes RoHS-compliant, commercial-grade packaging per Vishay's material categorization policy, while "5BT" specifies the packaging format: 13-inch diameter plastic tape and reel containing 3200 units. This differs from "52T", which indicates a 7-inch reel with 750 units. The S2D-E3/5BT is not AEC-Q101 qualified-only variants with "HE3" (e.g., S2DHE3/5BT) carry that qualification.
What is the reverse recovery time (trr) of the S2D-E3/5BT and how does it affect circuit design?
The S2D-E3/5BT has a typical reverse recovery time (trr) of 2.0 μs, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This standard recovery characteristic makes it appropriate for switching frequencies up to ~100 kHz, such as in automotive buck converters and industrial AC/DC supplies. Designers should avoid using the S2D-E3/5BT in >200 kHz topologies where faster diodes like ultrafast or Schottky types would reduce switching loss and EMI.
Does the S2D-E3/5BT have moisture sensitivity level (MSL) rating and what does it mean for assembly?
Yes, the S2D-E3/5BT meets MSL Level 1 per J-STD-020, with a maximum peak reflow temperature of 260 °C. This means the device can be placed directly into lead-free reflow ovens without pre-baking, simplifying SMT line integration. The MSL Level 1 rating reflects its robust moisture barrier from the DO-214AA (SMB) molding compound and is verified through standardized preconditioning tests, ensuring reliability in high-volume automated assembly.
