Product details
Overview
SMCG15AHE3/57T 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 15 V stand-off voltage (VWM), 16.7–18.5 V breakdown voltage (VBR) at 1 mA, 1500 W peak pulse power (10/1000 µs), 61.5 A peak pulse current (IPPM), and clamps to ≤24.4 V at rated surge - used in automotive sensor signal lines, industrial I/O ports, and MOSFET gate protection.
For engineers reviewing the SMCG15AHE3/57T datasheet, SMCG15AHE3/57T pinout, SMCG15AHE3/57T application, or SMCG15AHE3/57T equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), RoHS-compliant HE3 suffix marking, and bidirectional variant compatibility for system-level ESD and surge design validation.
Technical Context
The SMCG15AHE3/57T employs a glass-passivated silicon junction optimized for fast response (<1 ns) to transient events such as inductive switching spikes and lightning-induced surges. Its unidirectional polarity enables integration into DC-biased circuits where reverse conduction must be blocked while maintaining low clamping voltage under high-current transients.
Rated for TJ = –55 °C to +150 °C operation and qualified per AEC-Q101, it supports automotive-grade reliability with MSL Level 1 moisture sensitivity and matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 15 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin for protected circuit nodes. |
| VBR (min/max) | 16.7 V / 18.5 V at IT = 1 mA - Confirmed breakdown range ensures predictable turn-on threshold across production lots. |
| VC @ IPPM | ≤24.4 V at 61.5 A - Clamping voltage during full-rated 10/1000 µs surge; determines maximum stress on downstream ICs. |
| PPPM | 1500 W - Peak pulse power handling capability; validates suitability for ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 Level 4 surges. |
| ID @ VWM | ≤1.0 µA - Reverse leakage at stand-off voltage; critical for low-power sensor interfaces and battery-backed systems. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance on standard 8.0 mm × 8.0 mm copper pads; enables thermal derating calculations for sustained surge duty. |
| AEC-Q101 | Qualified - Validated for automotive applications including engine control units, ADAS sensors, and infotainment power rails. |
Pinout & Package
Package: SMCG (DO-215AB) - surface-mount, low-profile gull-wing leaded case with cathode band marking; meets UL 94 V-0 flammability rating and JEDEC MS-012AC mechanical outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to ground or lower-potential node in unidirectional configuration; carries surge current during clamping. |
| Cathode | Reverse-biased terminal | Marked with band; connected to protected line (e.g., CAN_H, LIN, sensor VOUT); defines polarity-sensitive placement. |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated chip junction | Enables stable VBR tolerance and long-term reliability under thermal cycling and humidity exposure. |
| AEC-Q101 qualification | Validates performance for automotive under-hood and chassis-mounted electronics requiring extended temperature and life testing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A-E3/57T | Same VWM (15 V), lower PPPM (400 W), SMA (DO-214AC) package, RθJA = 110 °C/W. | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a or IEC 61000-4-5 Level 4. | Select when board space is constrained and surge energy remains below 400 W; verify thermal margin with smaller pad layout. |
| SMCJ15AHE3/57T | Same VWM (15 V), identical PPPM (1500 W), but larger SMC (DO-214AB) package with higher IFSM (200 A) and RθJA = 50 °C/W. | Better thermal performance and higher surge repetition capability; requires more PCB area. | Prefer for high-duty-cycle industrial drives or automotive ECUs needing enhanced thermal headroom and repeated surge endurance. |
Compared with SMAJ15A-E3/57T, SMCG15AHE3/57T delivers 3.75× higher surge power handling in a smaller footprint; versus SMCJ15AHE3/57T, it trades 25 °C/W higher thermal resistance for 30% smaller board area - optimal for space-constrained AEC-Q101 designs where 75 °C/W RθJA suffices.

FAQ
What is the breakdown voltage range for SMCG15AHE3/57T?
The SMCG15AHE3/57T has a minimum breakdown voltage (VBR) of 16.7 V and a maximum of 18.5 V at a test current of 1 mA, as specified in the Vishay datasheet revision 09-Jan-2024. This range ensures consistent clamping behavior across manufacturing lots and supports precise overvoltage threshold design in circuits protected by SMCG15AHE3/57T.
Is SMCG15AHE3/57T suitable for automotive applications?
Yes, SMCG15AHE3/57T is AEC-Q101 qualified and manufactured with the HE3 suffix indicating RoHS compliance and automotive-grade reliability. It operates from –55 °C to +150 °C and meets MSL Level 1, making SMCG15AHE3/57T appropriate for engine control units, body electronics, and ADAS sensor interfaces.
What does the "HE3" suffix mean in SMCG15AHE3/57T?
The "HE3" suffix in SMCG15AHE3/57T denotes RoHS-compliant, AEC-Q101-qualified construction with matte tin-plated leads. It distinguishes this variant from industrial-grade E3 (non-AEC-Q101) and halogen-free HM3 versions, confirming that SMCG15AHE3/57T meets automotive qualification and environmental compliance requirements.
How does SMCG15AHE3/57T compare to bidirectional variants like SMCG15CA?
SMCG15AHE3/57T is unidirectional, with polarity marked by a cathode band, while SMCG15CA is bidirectional and unmarked. Both share identical VWM (15 V), VBR (16.7–18.5 V), and PPPM (1500 W), but SMCG15AHE3/57T blocks reverse current - making it ideal for DC-biased signal lines where polarity is fixed, unlike AC or differential buses requiring SMCG15CA.
What is the thermal resistance of SMCG15AHE3/57T and how does it affect layout?
SMCG15AHE3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8.0 mm × 8.0 mm copper pads per terminal. This value directly impacts PCB copper area requirements: reducing pad size increases RθJA, risking thermal runaway during repeated surges - so SMCG15AHE3/57T layout must follow Vishay's recommended footprint to maintain safe junction temperature.
