Product details
Overview
SMBG9.0C-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 9.0 V stand-off voltage (VWM), 10.0–11.1 V breakdown voltage (VBR) at 1 mA, 15.4 V maximum clamping voltage (VC) at 39.0 A peak pulse current, and 600 W peak pulse power rating with 10/1000 µs waveform - used in automotive sensor protection and industrial I/O interface surge suppression.
For engineers reviewing the SMBG9.0C-E3/5B datasheet, SMBG9.0C-E3/5B pinout, SMBG9.0C-E3/5B application, or SMBG9.0C-E3/5B equivalent, key selection criteria include bi-directional clamping capability, AEC-Q101 qualification, MSL Level 1 moisture sensitivity, 150 °C max junction temperature, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, with identical electrical characteristics forward and reverse - enabling robust protection of AC-coupled or differential signal paths without polarity constraints. Its glass-passivated junction ensures stable leakage performance and fast response time (<1 ns), while low incremental surge resistance supports effective energy diversion during ESD or lightning-induced surges.
The device is rated for 600 W peak pulse power under 10/1000 µs waveform at 0.01% duty cycle, derated linearly above 25 °C ambient per Fig. 2, and achieves thermal resistance of 100 °C/W (junction-to-ambient) on standard 0.2" × 0.2" copper pads - making it suitable for compact, thermally constrained PCB layouts in automotive and industrial modules.
Key Specifications

SMBG9.0C-E3/5B is a bi-directional TVS diode with symmetrical electrical characteristics in both directions. It has no polarity marking on the DO-215AA (SMBG) package body, and either terminal functions as anode or cathode depending on transient polarity - simplifying layout and eliminating orientation errors during automated placement.
Does SMBG9.0C-E3/5B meet automotive qualification standards?
Yes, SMBG9.0C-E3/5B is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD per JESD22-A114. This qualification confirms its suitability for under-hood and chassis-mounted automotive electronics where reliability under thermal and mechanical stress is mandatory.
What is the maximum clamping voltage of SMBG9.0C-E3/5B and at what current?
The maximum clamping voltage (VC) of SMBG9.0C-E3/5B is 15.4 V, measured at a peak pulse current (IPPM) of 39.0 A using the standardized 10/1000 µs waveform. This value is guaranteed across temperature and process variation, ensuring consistent protection margin for downstream 12 V-rated ICs.
How does SMBG9.0C-E3/5B differ from uni-directional variants like SMBG9.0A?
SMBG9.0C-E3/5B is bi-directional with identical VBR, VC, and IPPM in both polarities, while SMBG9.0A is uni-directional with a cathode band marking and only conducts in reverse. The "C" suffix explicitly denotes bi-directional functionality - critical for protecting AC signals, differential buses, or systems where transient polarity is unpredictable.
What PCB pad layout is recommended for optimal thermal and surge performance of SMBG9.0C-E3/5B?
