Product details
Overview
SMCG58AHE3/57T from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) surface-mount package, designed for robust overvoltage protection of sensitive electronics. It features a 58 V stand-off voltage (VWM), 64.4–71.2 V breakdown voltage (VBR) at 1 mA, 1500 W peak pulse power (10/1000 µs), 93 V maximum clamping voltage (VC) at 16 A IPPM, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMCG58AHE3/57T datasheet, SMCG58AHE3/57T pinout, SMCG58AHE3/57T application, or SMCG58AHE3/57T equivalent, key selection criteria include clamping performance under 10/1000 µs surge, thermal resistance (RθJA = 75 °C/W), unidirectional polarity with cathode band marking, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector, responding within picoseconds to transients exceeding its VWM. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at VWM), while the DO-215AB package supports high surge current handling (IPPM = 16 A) without thermal runaway under defined PCB layout conditions.
The device is rated for -55 °C to +150 °C junction temperature, meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), and delivers consistent clamping across temperature due to low incremental surge resistance - critical for protecting MOSFET gates, sensor signal lines, and microcontroller I/O in automotive and industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 58 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 64.4–71.2 V at 1 mA - Confirmed breakdown threshold range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping Voltage) | 93 V at 16 A IPPM - Peak voltage seen by protected circuit during 10/1000 µs surge; determines stress on downstream components. |
| PPPM (Peak Pulse Power) | 1500 W - Surge energy absorption capability under standard 10/1000 µs waveform; enables protection against ISO 7637-2 Pulse 1/2a/5a. |
| ID (Reverse Leakage) | <1.0 µA at VWM - Minimal standby current; avoids signal distortion or battery drain in always-on circuits. |
| TJ max. | +150 °C - Maximum junction temperature rating; supports operation in under-hood automotive and high-ambient industrial settings. |
| RθJA | 75 °C/W - Thermal resistance from junction to ambient on specified 8.0 mm × 8.0 mm pad layout; informs heatsinking requirements. |
Pinout & Package
Package: SMCG (DO-215AB) - surface-mount, gull-wing leaded case with cathode band marking; RoHS-compliant matte tin plating; meets UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to protected line in unidirectional configuration | Accepts surge current during clamping; must be routed with low-inductance trace to ground path. |
| Cathode | Current exit terminal in forward bias; marked with band; connected to system ground | Provides reference node for clamping action; requires low-impedance connection to chassis or power ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units, ADAS sensors, and infotainment interfaces. |
| Glass passivated junction | Ensures long-term stability of VBR and low parameter drift over temperature and lifetime. |
| Low profile DO-215AB package | Enables high-density PCB layouts and compatibility with standard SMT pick-and-place equipment. |
| MSL Level 1 rating | Allows single-reflow assembly without moisture sensitivity concerns; peak reflow up to 260 °C. |
| Excellent clamping ratio (VC/VBR ≈ 1.37) | Minimizes overvoltage overshoot during fast transients, reducing risk of IC latch-up or gate oxide damage. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ58A-E3/57T | Same VWM (58 V), but lower PPPM (400 W); SMA (DO-214AC) package; RθJA = 110 °C/W | Limited to lower-energy transients (e.g., ESD-only); unsuitable for load-dump or high-current inductive spikes | Select only when surge energy is ≤400 W and space constraints favor smaller SMA footprint. |
| SMCJ58AHE3/57T | Same VWM (58 V), higher PPPM (1500 W), identical DO-215AB package, but higher VC (94 V vs. 93 V) and same AEC-Q101 qualification | Functionally interchangeable; minor clamping voltage difference has negligible impact on protected circuit margin | Preferred for new designs requiring full 1500 W capability with identical mechanical fit and qualification. |

FAQ
What is the clamping voltage of SMCG58AHE3/57T at its rated peak pulse current?
The SMCG58AHE3/57T has a maximum clamping voltage (VC) of 93 V at 16 A peak pulse current (IPPM), measured under the standard 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during surge events. The SMCG58AHE3/57T maintains this clamping performance with low incremental resistance, ensuring consistent protection behavior.
Is SMCG58AHE3/57T suitable for automotive applications?
Yes, SMCG58AHE3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its -55 °C to +150 °C operating temperature range, MSL Level 1 reflow compatibility, and validated performance against ISO 7637-2 and ISO 16750-2 transients make it appropriate for engine control units, body electronics, and ADAS sensor interfaces. The SMCG58AHE3/57T meets all required stress tests per the AEC-Q101 standard.
How does the SMCG58AHE3/57T package differ from SMAJ or SMCJ series packages?
The SMCG58AHE3/57T uses the DO-215AB (SMCG) package - a gull-wing variant with wider lead spacing and optimized thermal pad layout compared to DO-214AC (SMA) and DO-214AB (SMC). Its RθJA of 75 °C/W (on 8.0 mm × 8.0 mm pads) is significantly lower than SMAJ58A-E3/57T's 110 °C/W, enabling better power dissipation. The SMCG58AHE3/57T also features tighter dimensional control for automated placement and higher surge current capability in the same footprint class.
What is the reverse leakage current specification for SMCG58AHE3/57T at its stand-off voltage?
The SMCG58AHE3/57T specifies a maximum reverse leakage current (ID) of 1.0 µA at its 58 V stand-off voltage (VWM), tested at 25 °C. This ultra-low leakage ensures minimal loading on high-impedance signal paths and prevents unnecessary power loss in battery-powered or always-on systems. The SMCG58AHE3/57T maintains this leakage performance across its full operating temperature range, supporting reliable long-term operation.
Can SMCG58AHE3/57T be used in bidirectional configurations?
No - SMCG58AHE3/57T is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. Bidirectional variants use the "CA" suffix (e.g., SMCG58CA). Using SMCG58AHE3/57T in a bidirectional application would result in forward conduction during negative transients, potentially damaging the device or failing to protect the circuit. For symmetrical surge protection, select the SMCG58CAHE3/57T variant instead of SMCG58AHE3/57T.
