Product details
Overview
SMB10J15A-E3/52 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, designed for high-energy surge protection on DC power rails and signal lines. It features a 15 V stand-off voltage (VWM), 16.7–18.5 V breakdown voltage (VBR) at 1 mA, 24.4 V clamping voltage (VC) at 41 A peak pulse current (IPPM), and 1000 W peak pulse power (PPPM) with 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMB10J15A-E3/52 datasheet, SMB10J15A-E3/52 pinout, SMB10J15A-E3/52 application, or SMB10J15A-E3/52 equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance (RθJA = 72 °C/W), RoHS-compliant commercial-grade construction, and real-world use context for ESD/surge hardening of 12 V automotive subsystems.
Technical Context
This unidirectional TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR (16.7–18.5 V), it avalanches to limit transient energy by diverting surge current to ground. Its glass-passivated junction ensures stable breakdown and low leakage (<1.0 µA at 15 V), while MSL Level 1 rating supports lead-free reflow up to 260 °C.
The device sustains 100 A non-repetitive forward surge (IFSM) and maintains clamping performance across -55 °C to +150 °C junction temperature range. Its 72 °C/W junction-to-ambient thermal resistance requires minimum 5.0 mm × 5.0 mm copper pad layout per terminal to achieve rated PPPM under repetitive stress conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15 V - maximum continuous reverse operating voltage before significant leakage; sets upper limit for protected line nominal voltage. |
| VBR (min/max) | 16.7 V / 18.5 V at 1.0 mA - guaranteed avalanche initiation window; defines minimum overvoltage threshold for clamping action. |
| VC @ IPPM | 24.4 V at 41 A - maximum clamped voltage during 10/1000 µs surge; determines worst-case stress on downstream ICs. |
| PPPM | 1000 W - peak pulse power handling with 10/1000 µs waveform; enables protection against ISO 7637-2 Pulse 1/2/5a transients. |
| RθJA | 72 °C/W - thermal resistance junction-to-ambient; requires ≥5.0 mm × 5.0 mm copper pads per terminal to sustain full power rating. |
| TJ max. | +150 °C - maximum junction temperature; supports operation in under-hood automotive environments. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22-A114. |
