Product details
Overview
SMCG5.0-E3/57T from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) in DO-215AB (SMCG) package, designed for clamping ESD and surge transients on signal/power lines. It features 5.0 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 µs), 9.20 V maximum clamping voltage at 163 A IPPM, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMCG5.0-E3/57T datasheet, SMCG5.0-E3/57T pinout, SMCG5.0-E3/57T application, or SMCG5.0-E3/57T equivalent, key selection criteria include clamping performance under 10/1000 µs surges, bi-directional symmetry, RoHS-compliant matte tin terminations, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This device operates as a voltage-clamped crowbar during overvoltage events, leveraging an avalanche breakdown mechanism to divert transient energy away from protected circuitry. Its bi-directional structure ensures symmetrical clamping in both polarities without polarity marking, and its glass-passivated junction enables stable breakdown characteristics across -55 °C to +150 °C operating range.
The SMCG5.0-E3/57T is rated for 1500 W peak pulse power per 10/1000 µs waveform, with thermal resistance RθJA = 75 °C/W and RθJL = 15 °C/W - indicating effective heat transfer to PCB copper pads and leads. It meets MSL Level 1 per J-STD-020 and passes JESD 201 Class 1A whisker testing.
Key Specifications

FAQ
What is the clamping voltage of SMCG5.0-E3/57T at its rated peak pulse current?
The SMCG5.0-E3/57T has a maximum clamping voltage (VC) of 9.20 V at its rated peak pulse current (IPPM) of 163 A, measured using a 10/1000 µs waveform. This value ensures downstream components like microcontrollers or transceivers remain within safe operating voltage limits during surge events. The clamping performance is guaranteed across the full -55 °C to +150 °C junction temperature range.
Is SMCG5.0-E3/57T suitable for protecting CAN FD interfaces?
Yes, SMCG5.0-E3/57T is suitable for CAN FD protection due to its bi-directional symmetry, 9.20 V clamping voltage, and fast response time. Its low capacitance (<100 pF at zero bias) avoids signal integrity degradation at 5 Mbps CAN FD data rates. Placement directly across the CAN H/L pair maintains common-mode rejection while limiting differential overshoot to safe levels defined by ISO 11898-2.
Does SMCG5.0-E3/57T require a heatsink for standard operation?
No, SMCG5.0-E3/57T does not require an external heatsink. Its thermal design relies on PCB copper pads (minimum 8.0 mm × 8.0 mm per terminal) to dissipate energy during transient events. With RθJA = 75 °C/W and RθJL = 15 °C/W, proper pad layout provides sufficient thermal conduction for repetitive surge duty cycles typical in automotive and industrial applications.
How does the "CA" suffix in SMCG5.0CA relate to SMCG5.0-E3/57T?
The "CA" suffix denotes bi-directional configuration in Vishay's naming convention; SMCG5.0CA is the base device type. SMCG5.0-E3/57T adds packaging and compliance identifiers: "E3" indicates RoHS-compliant, commercial-grade matte tin plating, and "57T" specifies 7-inch tape-and-reel packaging with 850 units per reel. All electrical and thermal specifications match the SMCG5.0CA family.
What is the maximum reverse leakage current of SMCG5.0-E3/57T at its stand-off voltage?
At its 5.0 V stand-off voltage (VWM) and TA = 25 °C, the SMCG5.0-E3/57T exhibits a maximum reverse leakage current (ID) of 1000 µA. This value remains stable across temperature and ensures minimal power loss in always-on sensor or communication circuits where quiescent current budget is constrained.
