Product details
Overview
SMCG13CAHE3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) surface-mount package, designed for robust overvoltage protection of sensitive electronics. It features a 13 V stand-off voltage (VWM), 1500 W peak pulse power rating (10/1000 µs), clamping voltage of 21.5 V at 69.8 A IPPM, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMCG13CAHE3/57T datasheet, SMCG13CAHE3/57T pinout, SMCG13CAHE3/57T application, or SMCG13CAHE3/57T equivalent, this device is selected for high-energy surge suppression on signal lines, power rails, and sensor interfaces where bidirectional clamping, low clamping ratio, and MSL Level 1 reflow compatibility are required.
Technical Context
The SMCG13CAHE3/57T implements a glass-passivated silicon avalanche junction optimized for fast response (<1 ns) to transient events such as ESD, lightning-induced surges, and inductive switching spikes. Its bidirectional architecture enables symmetric clamping in both polarities without polarity marking, supporting AC-coupled or floating signal paths.
Thermally, it delivers 6.5 W power dissipation at TA = 50 °C with RθJA = 75 °C/W and RθJL = 15 °C/W, enabling stable operation up to TJ = +150 °C. The device meets JESD201 Class 2 whisker resistance and UL 94 V-0 flammability requirements per its SMCG package molding compound.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse operating voltage before clamping begins; defines safe signal swing range. |
| VBR min/max | 14.4 V / 15.9 V at IT = 1 mA - Breakdown threshold tolerance ensures consistent turn-on across production lots. |
| VC @ IPPM | 21.5 V at 69.8 A - Clamping voltage under 10/1000 µs surge; determines maximum stress imposed on protected IC. |
| PPPM | 1500 W - Peak pulse power handling capacity; supports IEC 61000-4-5 Level 4 (4 kV/2 Ω) surge immunity. |
| ID @ VWM | 1.0 µA - Reverse leakage at stand-off voltage; negligible loading on high-impedance sensor or communication lines. |
| TJ max | +150 °C - Maximum junction temperature; enables use in under-hood automotive environments. |
| AEC-Q101 | Qualified - Validated for automotive electronic systems per stress test requirements including HTGB, HTRB, and TCT. |
Pinout & Package
Package: SMCG (DO-215AB) - Low-profile, gull-wing surface-mount case with matte tin-plated leads, compliant with J-STD-002 solderability and JESD22-B102 wetting balance testing. No polarity marking for bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (positive half-cycle) | One terminal of symmetrical avalanche junction; conducts during positive transients relative to cathode reference. |
| Cathode | Transient current entry (negative half-cycle) | Second terminal of symmetrical junction; conducts during negative transients - functionally identical to anode in bidirectional mode. |
Key Features

| AEC-Q101 qualification | Validates reliability for automotive infotainment, ADAS camera links, and body control modules operating in harsh thermal/vibration environments. |
| MSL Level 1 (260 °C peak) | Supports standard lead-free reflow profiles without preconditioning, eliminating moisture sensitivity handling overhead in SMT lines. |
| Glass passivated junction | Provides stable breakdown characteristics over time and temperature, minimizing parameter drift in long-life industrial deployments. |
Applications
| Automotive Sensor Protection | Industrial CAN Bus Interface |
|---|---|
|
Use Scenario: Protecting analog output lines of pressure, temperature, or position sensors in engine control units exposed to load-dump and alternator ripple. IC Role / Device Role / Timing Role: Bidirectional TVS placed between sensor output and microcontroller ADC input to clamp ±200 V transients. Use Value: Prevents latch-up or permanent damage to 12-bit ADC front-end while maintaining <1 µA leakage below 13 V nominal rail. |
Use Scenario: Surge protection on CAN_H/CAN_L differential pair in factory automation gateways subjected to EFT bursts and cable discharge events. IC Role / Device Role / Timing Role: One SMCG13CAHE3/57T per line (CAN_H–GND and CAN_L–GND) providing symmetrical clamping to limit common-mode voltage excursions. Use Value: Maintains CAN FD bit timing integrity by limiting clamped voltage to ≤21.5 V, avoiding recessive-to-dominant state corruption during 1 kV/50 Ω ESD events. |
| Consumer USB Type-C Port | Telecom DSL Line Interface |
|

Use Value: Achieves pass/fail compliance at Level 4 without derating due to 21.5 V clamping margin above 5 V VBUS and 3.3 V CC logic thresholds. |
Use Scenario: Primary surge protection on twisted-pair DSL subscriber lines entering residential gateways, exposed to induced lightning surges. IC Role / Device Role / Timing Role: SMCG13CAHE3/57T deployed across line-to-line and line-to-ground to clamp common-mode surges exceeding 1 kV. Use Value: Limits residual voltage to <22 V during 10/1000 µs 10 A surge, preserving ADSL2+ signal integrity and preventing PHY IC reset. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13CA | Same VWM (13 V) and PPPM (400 W), but lower 400 W rating and SMA (DO-214AC) package with higher RθJA (110 °C/W). | Limited to lower-energy transients (IEC 61000-4-5 Level 2); unsuitable for automotive under-hood locations requiring 150 °C TJ. | Select SMAJ13CA only for cost-sensitive consumer applications with <500 W surge exposure and ambient <85 °C. |
| 1.5KE13CA | Higher PPPM (1500 W) but axial-leaded DO-15 package; no MSL rating; 2× larger footprint and incompatible with automated SMT placement. | Requires manual assembly or wave soldering; not viable for high-density PCBs or AEC-Q101-compliant automotive designs. | Choose 1.5KE13CA only for prototyping or legacy through-hole systems where reflow compatibility and board space are non-constraints. |
Compared with SMAJ13CA and 1.5KE13CA, SMCG13CAHE3/57T uniquely combines AEC-Q101 qualification, MSL Level 1 reflow support, and DO-215AB's compact gull-wing layout-making it the only option for volume automotive SMT production requiring validated 1500 W bidirectional clamping in <3 mm² area.

The SMCG13CAHE3/57T clamps to a maximum of 21.5 V when subjected to its rated peak pulse current of 69.8 A using the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's Document Number 88457, ensuring predictable overvoltage limiting for downstream ICs.
Is SMCG13CAHE3/57T suitable for automotive applications?
Yes, SMCG13CAHE3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its +150 °C maximum junction temperature, MSL Level 1 reflow compatibility, and validation across HTGB, HTRB, and temperature cycling make it appropriate for ECUs, ADAS camera modules, and body control units.
Does SMCG13CAHE3/57T have polarity markings on the package?
No, SMCG13CAHE3/57T is a bidirectional TVS diode and carries no polarity marking on the SMCG (DO-215AB) case. The device functions identically regardless of orientation on the PCB, simplifying layout and eliminating risk of reverse installation during automated placement.
What is the maximum reverse leakage current of SMCG13CAHE3/57T at its stand-off voltage?
At its 13 V stand-off voltage (VWM) and TA = 25 °C, SMCG13CAHE3/57T exhibits a maximum reverse leakage current of 1.0 µA. This ultra-low leakage preserves signal integrity on high-impedance sensor outputs and communication lines without introducing measurable DC loading.
Which industry standards does SMCG13CAHE3/57T meet for surge immunity?
SMCG13CAHE3/57T supports compliance with IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (surge) up to Level 4 (4 kV line-to-earth, 2 Ω source impedance) due to its 1500 W PPPM rating and 21.5 V clamping voltage. It also meets UL 497B recognition for protector classification.
