Product details
Overview
SMBG13C-E3/5B from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-215AA (SMBG) package, designed for clamping voltage transients on signal or power lines. It features 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 μs), 27.9 A peak pulse current (IPPM), and 21.5 V maximum clamping voltage (VC) - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMBG13C-E3/5B datasheet, SMBG13C-E3/5B pinout, SMBG13C-E3/5B application, or SMBG13C-E3/5B equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, MSL Level 1 moisture sensitivity, 150 °C junction temperature rating, and compatibility with automated SMT placement on standard PCB pads.
Technical Context
This bi-directional TVS operates symmetrically in both polarities, with identical VBR min/max and VC specifications for positive and negative surges. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ps), enabling effective suppression of ESD (IEC 61000-4-2) and lightning-induced transients (IEC 61000-4-5).
The device uses a low-inductance DO-215AA package with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102, and meets UL 94 V-0 flammability. Thermal resistance is RθJA = 100 °C/W (on 5.0 mm × 5.0 mm copper pads), supporting reliable operation up to TJ = 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - maximum continuous reverse operating voltage before clamping begins; defines safe working range for protected line. |
| VBR (min/max) | 14.4 V / 15.9 V at 1 mA - guaranteed breakdown threshold; ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 21.5 V at 27.9 A - clamped voltage under 10/1000 μs surge; determines maximum stress imposed on downstream ICs. |
| PPPM | 600 W - peak pulse power handling capacity; supports robust protection against repetitive transients at 0.01% duty cycle. |
| ID @ VWM | ≤1.0 μA - ultra-low reverse leakage; minimizes standby power loss and avoids false triggering in high-impedance circuits. |
| TJ max. | 150 °C - maximum junction temperature; enables use in under-hood automotive and industrial environments. |
| Qualification | AEC-Q101 qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing. |
