Product details
Overview
SMCG5.0HE3/57T from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) in DO-215AB (SMCG) package, designed for clamping voltage transients on signal and power lines. It features 5.0 V stand-off voltage (VWM), 1500 W peak pulse power (PPPM), 9.20 V maximum clamping voltage (VC) at 163 A IPPM, and AEC-Q101 qualification for automotive reliability.
For engineers reviewing the SMCG5.0HE3/57T datasheet, SMCG5.0HE3/57T pinout, SMCG5.0HE3/57T application, or SMCG5.0HE3/57T equivalent, key selection criteria include bi-directional surge protection capability, low clamping ratio (VC/VWM = 1.84), MSL Level 1 moisture sensitivity, and RoHS-compliant matte tin terminations suitable for automated SMT assembly.
Technical Context
This device operates as a bi-directional avalanche diode, leveraging glass-passivated silicon junctions to achieve sub-nanosecond response time and low incremental surge resistance. Its symmetrical breakdown behavior ensures identical clamping performance in both polarities, with no polarity marking required on the package.
The SMCG5.0HE3/57T is rated for -55 °C to +150 °C operating junction temperature and exhibits 75 °C/W typical thermal resistance (junction-to-ambient) on standard 8.0 mm × 8.0 mm copper pads. It meets UL 94 V-0 flammability and JESD 201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 5.0 V - Maximum continuous reverse voltage before significant leakage; defines operating margin below clamping threshold |
| VC (Clamping Voltage) | 9.20 V at 163 A - Peak voltage seen by protected circuit during 10/1000 µs surge; determines downstream component stress |
| PPPM (Peak Pulse Power) | 1500 W - Surge energy handling capacity under standardized 10/1000 µs waveform; enables robust ESD/Lightning-level protection |
| ID (Leakage Current) | 1000 µA max at VWM - Low standby current minimizes power loss in always-on interfaces like CAN or LIN bus |
| TJ max | +150 °C - Enables operation in under-hood automotive environments and industrial enclosures without derating |
| MSL Level | Level 1 per J-STD-020 - Supports standard reflow profiles up to 260 °C peak without baking or special handling |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification |
Pinout & Package

Applications
| Automotive Sensor Protection | Industrial RS-485 Interface |
|---|---|
Use Scenario: Protecting wheel speed, pressure, or temperature sensor outputs exposed to load dump and ISO 7637-2 pulses in vehicle chassis wiring. IC Role / Device Role / Timing Role: Bi-directional TVS placed at connector entry point to clamp transients before reaching analog front-end or microcontroller ADC inputs. Use Value: Clamps 163 A surges to ≤9.20 V while maintaining 5.0 V signal integrity during normal operation-preserving sensor accuracy and enabling AEC-Q100-compliant system design. |
Use Scenario: Safeguarding half-duplex RS-485 transceivers (e.g., SN65HVD230) in factory automation PLCs subject to ground loop surges and cable discharge events. IC Role / Device Role / Timing Role: Differential-line TVS across A/B bus lines to suppress common-mode transients without distorting data eye diagram. Use Value: 9.20 V clamping voltage ensures receiver input remains within ±7 V common-mode range, preventing false triggering and bus lock-up during 1 kV EFT bursts. |
| Consumer USB-C Port | Telecom DSL Line Interface |
Use Scenario: Protecting USB-C CC and SBU pins against electrostatic discharge during hot-plug events in portable docking stations. IC Role / Device Role / Timing Role: Localized TVS adjacent to connector to absorb >15 kV HBM ESD pulses before reaching USB PD controller or level translators. Use Value: Sub-ns response time and 1000 µA leakage at 5.0 V prevent signal degradation on high-speed sideband use (SBU) channels while meeting IEC 61000-4-2 Level 4 compliance. |
Use Scenario: Shielding ADSL/VDSL line drivers and receivers from lightning-induced surges entering via outdoor telephone lines in residential gateways. IC Role / Device Role / Timing Role: Primary protection stage between transformer secondary and line driver IC, shunting surge energy to ground. Use Value: 1500 W PPPM rating handles 10/1000 µs lightning surges up to 4 kV; DO-215AB footprint allows compact placement near line transformer without compromising creepage distance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A-E3/57T | Uni-directional; 5.0 V VWM, 9.2 V VC, but lacks AEC-Q101 qualification and has higher leakage (500 µA @ VWM) | Restricted to DC-biased circuits where polarity is fixed; unsuitable for AC or differential lines without external biasing | Select only when cost sensitivity outweighs automotive qualification and bi-directional flexibility |
| SMCJ5.0AHE3/57T | Same AEC-Q101 qualification and DO-215AB package, but uni-directional with cathode band; identical VWM/VC/PPPM specs | Requires polarity-aware layout; cannot protect floating or AC-coupled nodes without redesign | Choose only if existing board uses uni-directional topology and replacement must retain same pin orientation |
Compared with SMAJ5.0A-E3/57T and SMCJ5.0AHE3/57T, the SMCG5.0HE3/57T uniquely delivers bi-directional clamping with automotive qualification in the same footprint-enabling drop-in upgrades for RS-485, CAN, or USB-C designs without layout changes or polarity validation.

FAQ
What does the 'HE3' suffix indicate in SMCG5.0HE3/57T?
The 'HE3' suffix in SMCG5.0HE3/57T denotes RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance. It distinguishes this automotive-grade variant from commercial 'E3' versions and confirms compliance with stringent automotive reliability testing protocols.
Is SMCG5.0HE3/57T suitable for protecting CAN FD bus lines?
Yes, SMCG5.0HE3/57T is well-suited for CAN FD protection due to its bi-directional symmetry, 5.0 V VWM matching nominal bus common-mode range, and 9.20 V clamping voltage that stays within ISO 11898-2 fault tolerance limits. Its low capacitance (<100 pF) also preserves signal integrity at 5 Mbps data rates.
What is the maximum clamping voltage of SMCG5.0HE3/57T under surge conditions?
The maximum clamping voltage (VC) of SMCG5.0HE3/57T is 9.20 V, measured at 163 A peak pulse current (IPPM) using the standardized 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and forms the basis for downstream component overvoltage margining.
Does SMCG5.0HE3/57T require a heatsink for 6.5 W continuous power dissipation?
No, SMCG5.0HE3/57T achieves its 6.5 W power dissipation rating (PD) at TA = 50 °C with no external heatsink-relying on PCB copper pad thermal conduction. The specified 0.31" × 0.31" (8.0 mm × 8.0 mm) copper area per terminal provides sufficient thermal path for typical automotive and industrial ambient conditions.
How does the DO-215AB package of SMCG5.0HE3/57T compare to SMA or SMB footprints?
The DO-215AB (SMCG) package of SMCG5.0HE3/57T offers 30% lower profile and 15% smaller footprint than SMA while maintaining higher surge current capability than SMB. Its gull-wing leads improve solder joint reliability versus J-lead packages and support finer-pitch routing in space-constrained layouts.
