Product details
Overview
SMCG13AHE3/57T from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) package, designed for robust overvoltage protection of sensitive electronics. It features a 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR) at 1 mA, 21.5 V clamping voltage (VC) at 69.8 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM) with a 10/1000 µs waveform - deployed on power rails and signal lines in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the SMCG13AHE3/57T datasheet, SMCG13AHE3/57T pinout, SMCG13AHE3/57T application, or SMCG13AHE3/57T equivalent, key selection criteria include its AEC-Q101 qualification, low incremental surge resistance, bidirectional-capable variant compatibility (e.g., SMCG13CA), and DO-215AB thermal performance under high-energy transients per IEC 61000-4-5.
Technical Context
This TVS diode operates as a clamping device that transitions from high-impedance to low-impedance state within picoseconds upon exceeding VBR, diverting surge current away from protected circuitry. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and repeatable breakdown behavior across temperature (-55 °C to +150 °C).
The SMCG13AHE3/57T is rated for 1500 W peak pulse power with a 10/1000 µs waveform, derated above 25 °C per Fig. 2, and exhibits a typical junction-to-lead thermal resistance (RθJL) of 15 °C/W - enabling effective heat dissipation when mounted on 8.0 mm × 8.0 mm copper pads per JEDEC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - maximum continuous reverse operating voltage before clamping initiates; defines safe DC/AC signal rail margin. |
| VBR (min/max) | 14.4 V / 15.9 V at 1 mA - precise breakdown threshold ensuring predictable turn-on during transients. |
| VC @ IPPM | 21.5 V at 69.8 A - clamped voltage level protecting downstream ICs with <22 V absolute max rating. |
| PPPM | 1500 W - peak surge energy handling capability compliant with IEC 61000-4-5 Level 4 (4 kV/2 kA). |
| ID @ VWM | ≤1.0 µA - ultra-low leakage preserves signal integrity and battery life in always-on circuits. |
| TJ max. | +150 °C - extended junction temperature range supports under-hood automotive and industrial environments. |
| RθJL | 15 °C/W - enables efficient heat transfer to PCB copper, critical for repetitive surge reliability. |
Pinout & Package
Package: SMCG (DO-215AB) - surface-mount, low-profile gull-wing leaded package with matte tin-plated terminals, MSL Level 1 (260 °C reflow peak), UL 94 V-0 molding compound, and AEC-Q101 qualification. Polarity marked by cathode band on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to ground or lower-potential node in unidirectional configuration. | Provides reference path for clamping action; must be routed with low-inductance trace to minimize overshoot. |
| Cathode | Current exit terminal in forward bias; connected to protected line (e.g., CAN_H, 12 V rail, sensor output). | Band-marked end; determines directionality - reversal yields open-circuit behavior above VWM. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for engine control, ADAS, and body electronics. |
| Glass passivated junction | Ensures long-term parameter stability and low leakage drift over 15+ years in harsh environments. |
| Low incremental surge resistance | Minimizes VC rise under high di/dt events - critical for protecting fast-switching MOSFET gates and microcontroller I/O. |
| MSL Level 1 compliance | Supports standard SMT reflow without moisture sensitivity concerns - eliminates bake requirements pre-assembly. |
| 1500 W 10/1000 µs rating | Handles worst-case load dump and inductive switching surges in 12 V systems without degradation. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V supply inputs in engine control units against ISO 7637-2 pulse 5a (load dump) and pulse 1/2a (inductive switching). IC Role / Device Role: Primary clamping element placed between battery feed and LDO input, shunting >100 A transients. Use Value: Limits voltage to ≤21.5 V during 1500 W surges, preventing LDO overvoltage failure and system reset. |
Use Scenario: Safeguarding analog outputs (e.g., 4–20 mA, 0–10 V) of pressure/temperature sensors in factory automation PLC modules. IC Role / Device Role: Bidirectional-capable protection (via SMCG13CA variant) on signal lines exposed to ESD and cable discharge events. Use Value: Maintains signal fidelity with <1.0 µA leakage while clamping ±21.5 V transients - preserving 16-bit ADC accuracy. |
| Telecom Line Card Surge Suppression | Consumer USB Power Delivery Protection |
Use Scenario: Front-end protection of Ethernet PHY power supplies (3.3 V, 5 V) in PoE-powered switches subjected to lightning-induced surges. IC Role / Device Role: Secondary TVS stage after gas discharge tube (GDT), absorbing residual energy after GDT crowbar action. Use Value: 1500 W rating handles residual 10/1000 µs tail energy; RθJL = 15 °C/W prevents thermal runaway during repeated strikes. |
Use Scenario: Overvoltage clamp on VBUS line of USB-C receptacles in portable monitors, guarding against adapter fault conditions. IC Role / Device Role: Unidirectional clamp referenced to ground, activated only during positive VBUS overvoltage (>13 V). Use Value: Fast response (<1 ns) and low VC ensure USB PD controller remains within 24 V ABS MAX rating during 20 V adapter faults. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A-E3/57T | 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 61000-4-2 ESD only); unsuitable for ISO 7637-2 load dump. | Select when cost sensitivity outweighs surge margin and board space allows larger thermal pad area. |
| SMCJ13AHE3/57T | Identical VWM (13 V), VBR (14.4–15.9 V), and PPPM (1500 W), but in SMC (DO-214AB) package with 10% larger footprint and 20% higher RθJA. | Compatible in same circuit but requires revised layout; slightly reduced thermal efficiency in high-density designs. | Choose if existing SMC footprint is standardized and DO-215AB requalification is impractical. |
Compared with SMAJ13A-E3/57T and SMCJ13AHE3/57T, the SMCG13AHE3/57T delivers identical electrical protection with superior thermal performance (RθJL = 15 °C/W vs. ≥18 °C/W) and smaller DO-215AB footprint - optimizing space-constrained automotive and industrial PCBs.

FAQ
What is the clamping voltage of SMCG13AHE3/57T at its rated peak pulse current?
The SMCG13AHE3/57T has a maximum clamping voltage (VC) of 21.5 V at 69.8 A peak pulse current (IPPM) with a 10/1000 µs waveform. This value is measured under standardized test conditions per JEDEC and ensures protected circuitry remains below critical voltage thresholds during surge events. The SMCG13AHE3/57T maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C).
Is SMCG13AHE3/57T suitable for automotive applications?
Yes, SMCG13AHE3/57T is AEC-Q101 qualified and explicitly designed for automotive use, including engine control units, body electronics, and ADAS modules. Its construction features glass-passivated junctions, MSL Level 1 reflow compatibility, and operation up to +150 °C junction temperature - all verified per AEC stress test requirements. The SMCG13AHE3/57T meets ISO 7637-2 pulse 5a (load dump) and IEC 61000-4-5 surge immunity standards when properly mounted.
How does the DO-215AB package of SMCG13AHE3/57T improve thermal performance compared to SMA or SMC packages?
The DO-215AB (SMCG) package of SMCG13AHE3/57T achieves a typical junction-to-lead thermal resistance (RθJL) of 15 °C/W - lower than SMA (DO-214AC, ~25 °C/W) and SMC (DO-214AB, ~18 °C/W). This results from optimized internal leadframe geometry and direct thermal path to gull-wing leads. In practice, the SMCG13AHE3/57T sustains repetitive 1500 W surges with less junction temperature rise, reducing derating needs and improving long-term reliability in high-ambient environments.
What is the maximum reverse leakage current of SMCG13AHE3/57T at its stand-off voltage?
The SMCG13AHE3/57T exhibits a maximum reverse leakage current (ID) of 1.0 µA at its 13 V stand-off voltage (VWM) and 25 °C ambient temperature. This ultra-low leakage is maintained across its full operating temperature range and ensures minimal power loss in battery-backed or always-on systems. The SMCG13AHE3/57T's glass-passivated junction contributes to consistent leakage behavior over time and thermal cycling.
Can SMCG13AHE3/57T be used in bidirectional configurations?
No - SMCG13AHE3/57T is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. For bidirectional operation, the functionally matched part is SMCG13CA (with "CA" suffix), which provides symmetrical clamping in both polarities and identical VWM (13 V), VBR (14.4–15.9 V), and VC (21.5 V) ratings. The SMCG13AHE3/57T must be oriented with cathode toward the protected line; reverse connection renders it non-functional for overvoltage protection.
