Product details
Overview
SMCG5.0HE3/9AT 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 max clamping voltage at 163 A IPPM, AEC-Q101 qualification, and RoHS compliance - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMCG5.0HE3/9AT datasheet, SMCG5.0HE3/9AT pinout, SMCG5.0HE3/9AT application, or SMCG5.0HE3/9AT equivalent, key selection criteria include bi-directional clamping capability, low clamping voltage under 163 A surge, AEC-Q101 qualification for automotive use, thermal resistance (RθJA = 75 °C/W), and DO-215AB surface-mount compatibility with automated placement.
Technical Context
The SMCG5.0HE3/9AT is a glass-passivated, bi-directional TVS diode optimized for fast response (<1 ns) to transient overvoltages induced by inductive switching or ESD events. Its symmetrical breakdown behavior (VBR min/max = 6.40–7.07 V at 10 mA) ensures identical clamping in both polarities, with no polarity marking required on the device body.
It operates across -55 °C to +150 °C junction temperature range, supports 1000 µA max reverse leakage at 5.0 V, and delivers 9.20 V clamping at 163 A peak pulse current (10/1000 µs waveform). Thermal design relies on 0.31" × 0.31" copper pads per terminal to sustain 6.5 W power dissipation at TA = 50 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - maximum continuous reverse operating voltage before clamping begins |
| PPPM | 1500 W - peak transient energy absorption capability under standardized 10/1000 µs surge |
| VC @ IPPM | 9.20 V - clamped voltage seen by protected circuit during 163 A surge event |
| VBR | 6.40–7.07 V @ 10 mA - symmetric breakdown threshold confirming bi-directional operation |
| ID @ VWM | 1000 µA - low leakage ensures minimal impact on high-impedance signal lines |
| TJ max. | +150 °C - enables use in under-hood automotive environments and industrial enclosures |
| RθJA | 75 °C/W - thermal resistance defines required PCB copper area for safe power dissipation |
Pinout & Package
Package: DO-215AB (SMCG), surface-mount gull-wing lead frame with matte tin-plated terminals, MSL Level 1 (260 °C reflow peak), UL 94 V-0 molding compound. No polarity marking - bi-directional symmetry eliminates cathode/anode distinction.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0AHE3/A | DO-214AC (SMA) package; 1000 W PPPM; higher RθJA (110 °C/W); same VWM/VC specs | Larger footprint; lower surge rating; less suitable for high-density automotive PCBs | Select when DO-214AC is already standardized in BOM and 1000 W suffices |
| 1.5KE5.0CA | Through-hole DO-201 package; 1500 W PPPM; same VWM/VC; no AEC-Q101 qualification | Requires wave soldering; unsuitable for fully SMT automotive designs | Select only for cost-sensitive industrial prototypes where AEC-Q101 is not mandated |
Compared with SMAJ5.0AHE3/A and 1.5KE5.0CA, the SMCG5.0HE3/9AT offers superior board-space efficiency via DO-215AB, guaranteed AEC-Q101 compliance for automotive deployment, and lower thermal resistance - enabling higher sustained surge duty cycles in compact layouts.

FAQ
What is the clamping voltage of SMCG5.0HE3/9AT at its rated peak pulse current?
The SMCG5.0HE3/9AT exhibits a maximum clamping voltage (VC) of 9.20 V when subjected to its rated peak pulse current (IPPM) of 163 A under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures protected circuits remain within safe operating limits during surge events. The low VC directly contributes to system-level robustness in automotive and industrial applications where downstream ICs have tight absolute maximum voltage ratings.
Is SMCG5.0HE3/9AT suitable for automotive applications?
Yes, SMCG5.0HE3/9AT is AEC-Q101 qualified and explicitly designed for automotive use. Its qualification covers temperature cycling, high-temperature reverse bias (HTRB), and ESD testing per JESD22 standards. The HE3 suffix confirms compliance with JESD201 Class 2 whisker resistance and RoHS Directive 2011/65/EU. It is deployed in engine control units, body electronics, and ADAS sensor interfaces where reliability under harsh environmental conditions is mandatory.
What does the 'HE3' suffix indicate in SMCG5.0HE3/9AT?
The 'HE3' suffix in SMCG5.0HE3/9AT denotes two critical attributes: 'H' indicates AEC-Q101 qualification for automotive-grade reliability, and 'E3' specifies RoHS compliance with JESD201 Class 2 whisker resistance. This distinguishes it from commercial-grade 'E3' variants (e.g., SMCG5.0A-E3/9AT) and confirms suitability for mission-critical automotive electronics where long-term stability and process compatibility are essential.
How does the DO-215AB package of SMCG5.0HE3/9AT compare to DO-214AC in thermal performance?
The DO-215AB package of SMCG5.0HE3/9AT achieves a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" copper pads - significantly lower than the ~110 °C/W typical for DO-214AC packages like SMAJ5.0AHE3/A. This 32% improvement enables higher sustained power dissipation and better thermal margin in dense automotive PCB layouts, reducing risk of thermal runaway during repetitive surge events.
Does SMCG5.0HE3/9AT require polarity-aware PCB layout?
No, SMCG5.0HE3/9AT is a bi-directional TVS diode with symmetrical electrical characteristics in both directions, and its DO-215AB package carries no polarity marking. The device functions identically regardless of orientation on the PCB - eliminating layout constraints and assembly errors associated with cathode band alignment. This simplifies design reuse across differential signal pairs and AC-coupled interfaces where polarity reversal may occur.
