Product details
Overview
SMCG16CAHE3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) package, designed for robust overvoltage protection on signal and power lines. It features a 16 V stand-off voltage (VWM), 17.8–19.7 V breakdown voltage (VBR), 1500 W peak pulse power (PPPM), and clamps to ≤26.0 V at 57.7 A (10/1000 µs waveform), making it suitable for automotive sensor interface and industrial I/O line protection.
For engineers reviewing the SMCG16CAHE3/57T datasheet, SMCG16CAHE3/57T pinout, SMCG16CAHE3/57T application, or SMCG16CAHE3/57T equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, 1500 W surge rating, DO-215AB thermal performance (RθJA = 75 °C/W), and RoHS-compliant HE3 suffix indicating automotive-grade reliability.
Technical Context
This device operates as a voltage-clamped crowbar during transients, leveraging an avalanche breakdown mechanism with glass-passivated junction for stable, repeatable clamping. Its bidirectional symmetry ensures identical electrical behavior in both polarities - critical for AC-coupled or floating signal paths.
Designed for surface-mount automated assembly, it meets J-STD-020 MSL Level 1 (260 °C peak reflow) and JESD201 Class 2 whisker resistance. The SMCG package provides low-profile mounting (max height 0.058") and optimized thermal dissipation via 8.0 mm × 8.0 mm copper pads per terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR min/max | 17.8 V / 19.7 V at 1.0 mA - guaranteed avalanche onset range under standardized test current |
| VC @ IPPM | 26.0 V at 57.7 A - clamping voltage during 10/1000 µs surge, defining worst-case protected circuit stress |
| PPPM | 1500 W - peak transient power handling capacity, enabling protection against IEC 61000-4-5 Level 4 surges |
| TJ max | +150 °C - maximum junction temperature, supporting operation in under-hood automotive environments |
| Package | SMCG (DO-215AB) - industry-standard gull-wing SMD outline with 0.31" × 0.31" pad footprint and 75 °C/W θJA |
Pinout & Package
SMCG16CAHE3/57T uses the SMCG (DO-215AB) surface-mount package: gull-wing leads, no polarity marking (bidirectional), matte tin-plated terminals solderable per J-STD-002, and compliant with UL 94 V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (positive polarity) | One of two symmetrical terminals; conducts during positive transients relative to cathode reference |
| Cathode | Transient current entry (negative polarity) | Second symmetrical terminal; conducts during negative transients - functionally identical to anode in bidirectional mode |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control, ADAS sensors, and infotainment interfaces |
| Glass-passivated junction | Ensures stable VBR over lifetime and immunity to humidity-induced parameter drift |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (e.g., ISO 7637-2 pulse 1/2a) |
| MSL Level 1 rating | Enables single-pass reflow without moisture sensitivity concerns, reducing manufacturing risk |
Applications
| Automotive Sensor Protection | Industrial I/O Interface |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor outputs (e.g., pressure, temperature) from load-dump and inductive switching transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional voltage clamp placed across differential or single-ended signal lines upstream of the receiver input. Use Value: Limits transient voltage to ≤26.0 V, preventing damage to 3.3 V/5 V interface ICs while maintaining signal integrity due to low capacitance (<100 pF at 0 V). | Use Scenario: Safeguarding PLC digital input modules and fieldbus nodes (RS-485, Profibus) against ESD and lightning-induced surges in factory automation. IC Role / Device Role / Timing Role: Primary front-end TVS on signal/power rails, absorbing up to 1500 W of energy per event without degradation. Use Value: Enables compliance with IEC 61000-4-2 (±8 kV contact) and IEC 61000-4-5 (2 Ω/12 Ω coupling, 4 kV), reducing system-level failure rates. |
| Consumer Power Adapter Input | Telecom Line Card Protection |
Use Scenario: Secondary-side overvoltage suppression on 12–24 V DC outputs of wall adapters and USB-PD auxiliary supplies. IC Role / Device Role / Timing Role: Standoff-clamp device placed between output rail and ground, triggered only during fault conditions. Use Value: Maintains 16 V nominal operation while clamping surges to 26.0 V, protecting downstream regulators and USB controllers without affecting steady-state efficiency. | Use Scenario: Protecting Ethernet PHYs and DSL line drivers from induced surges on twisted-pair telecom lines exposed to outdoor environments. IC Role / Device Role / Timing Role: Bidirectional shunt protector on differential pairs, leveraging symmetric VBR to avoid polarity-dependent misclamping. Use Value: Delivers matched clamping in both directions (≤26.0 V), eliminating need for dual unidirectional devices and saving PCB area in space-constrained line cards. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16CA | Same VWM (16 V) and PPPM (400 W), but lower surge rating (400 W vs. 1500 W); SMA package (DO-214AC), higher RθJA (~110 °C/W) | Not suitable for high-energy surge environments like automotive load dump or industrial 4 kV IEC 61000-4-5 testing | Select SMAJ16CA only for cost-sensitive, low-surge consumer applications where board space is constrained and thermal margin is sufficient. |
| SMCJ16CA | Identical VWM (16 V), PPPM (1500 W), and DO-214AB package; differs in AEC-Q101 qualification status (SMCJ16CA is not AEC-Q101 rated) | Lacks automotive qualification evidence; may require additional validation for under-hood use | Choose SMCJ16CA for industrial or telecom applications requiring same electrical specs but without automotive certification requirements. |
Compared with SMAJ16CA and SMCJ16CA, SMCG16CAHE3/57T uniquely combines 1500 W surge capability, AEC-Q101 qualification, and DO-215AB thermal performance (75 °C/W), making it the only option qualified for automotive-grade transient protection without derating or secondary validation.

FAQ
What is the clamping voltage of SMCG16CAHE3/57T at its rated peak pulse current?
The SMCG16CAHE3/57T clamps to a maximum of 26.0 V when subjected to its rated peak pulse current of 57.7 A under the standard 10/1000 µs waveform. This value is measured at the device terminals with the recommended 8.0 mm × 8.0 mm copper pad layout and defines the upper voltage limit imposed on protected circuits during surge events.
Is SMCG16CAHE3/57T suitable for automotive applications?
Yes, SMCG16CAHE3/57T is AEC-Q101 qualified and carries the HE3 suffix denoting RoHS compliance and automotive-grade qualification. It is explicitly rated for operation from −55 °C to +150 °C and validated for use in engine control units, ADAS sensor interfaces, and body electronics where transient immunity and long-term reliability are mandatory.
What does the "CA" suffix indicate in SMCG16CAHE3/57T?
The "CA" suffix in SMCG16CAHE3/57T designates a bidirectional configuration, meaning the device provides symmetrical transient suppression in both polarities. Electrical characteristics-including VBR, VC, and IPPM-apply identically in either direction, eliminating polarity marking and simplifying placement on AC-coupled or floating signal lines.
How does the SMCG (DO-215AB) package compare thermally to SMA (DO-214AC) or SMC (DO-214AB)?
The SMCG (DO-215AB) package delivers a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W with the recommended 8.0 mm × 8.0 mm pad layout-significantly lower than SMA (≈110 °C/W) and comparable to SMC (≈70–75 °C/W). This enables higher sustained power dissipation and improved reliability in thermally constrained layouts.
What is the maximum reverse leakage current of SMCG16CAHE3/57T at its stand-off voltage?
At its 16 V stand-off voltage (VWM), SMCG16CAHE3/57T exhibits a maximum reverse leakage current (ID) of 1.0 µA at 25 °C. This ultra-low leakage preserves signal integrity and minimizes standby power loss in high-impedance sensor and communication circuits.
