Product details
Overview
SMCG58CA-M3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) surface-mount package, designed for high-energy surge protection with 1500 W peak pulse power (10/1000 µs), 58 V stand-off voltage (VWM), and 93 V maximum clamping voltage (VC) at rated IPPM. It is AEC-Q101 qualified and halogen-free, targeting automotive power line and sensor interface protection.
For engineers reviewing the SMCG58CA-M3/57T datasheet, SMCG58CA-M3/57T pinout, SMCG58CA-M3/57T application, or SMCG58CA-M3/57T equivalent, this page delivers verified electrical parameters, bidirectional polarity behavior, thermal resistance (RθJA = 75 °C/W), MSL Level 1 compliance, and direct substitution guidance against industry-standard TVS alternatives.
Technical Context
The SMCG58CA-M3/57T operates as a bidirectional avalanche diode, exhibiting symmetrical breakdown characteristics in both polarities with minimum/maximum breakdown voltages of 64.4 V and 71.2 V at 1 mA test current. Its low incremental surge resistance and fast response time enable effective suppression of ESD, lightning-induced transients, and inductive switching spikes.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads per terminal, it delivers 1500 W peak pulse power under standardized 10/1000 µs waveform conditions and maintains stable operation across -55 °C to +150 °C junction temperature range, with thermal resistance from junction to ambient rated at 75 °C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 58 V - Maximum continuous reverse operating voltage before clamping begins; defines safe signal/power rail operating margin. |
| VBR min/max | 64.4 V / 71.2 V at IT = 1 mA - Confirmed bidirectional breakdown threshold range; ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 93 V - Clamped voltage at peak pulse current; determines maximum stress imposed on protected downstream circuitry. |
| PPPM | 1500 W - Peak pulse power handling capability under 10/1000 µs waveform; quantifies transient energy absorption capacity. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance on standard 8.0 mm × 8.0 mm pad layout; critical for thermal derating above 25 °C. |
| TJ max | +150 °C - Maximum allowable junction temperature; sets upper limit for sustained power dissipation and reliability lifetime. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification. |

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 | Unidirectional; same VWM (58 V), but asymmetric clamping (VC = 93.6 V only in reverse direction); lower PPPM (400 W). | Limited to DC-biased rails where polarity is fixed; unsuitable for AC or floating signals. | Select when cost sensitivity outweighs bidirectionality and surge rating requirements. |
| 1.5KE58CA | Through-hole DO-201 package; identical VWM (58 V), VC (93 V), and PPPM (1500 W); higher RθJA (~50 °C/W on larger pads). | Requires PCB real estate and wave-solder process; less suitable for high-density automotive modules. | Prefer for legacy designs or prototyping where manual assembly or thermal mass is advantageous. |
Compared with SMAJ58A-E3/57T and 1.5KE58CA, the SMCG58CA-M3/57T uniquely combines bidirectional operation, surface-mount compatibility, AEC-Q101 qualification, and MSL Level 1 reflow readiness-making it optimal for next-generation automotive and industrial SMT assemblies where polarity flexibility and process robustness are mandatory.

FAQ
What is the breakdown voltage tolerance for SMCG58CA-M3/57T?
The SMCG58CA-M3/57T has a guaranteed breakdown voltage range of 64.4 V to 71.2 V at 1 mA test current (VBR min/max), measured bidirectionally per ANSI/IEEE C62.35 standards. This tolerance ensures consistent clamping onset across production lots and temperature extremes, directly supporting design margin calculations for protected circuits.
Is SMCG58CA-M3/57T suitable for automotive applications?
Yes, SMCG58CA-M3/57T is AEC-Q101 qualified and manufactured with halogen-free, RoHS-compliant materials. Its -55 °C to +150 °C operating range, MSL Level 1 reflow rating, and validated surge performance make it appropriate for engine control, body electronics, and ADAS modules where transient immunity and long-term reliability are required.
How does the clamping voltage of SMCG58CA-M3/57T compare to its stand-off voltage?
The SMCG58CA-M3/57T has a stand-off voltage (VWM) of 58 V and a maximum clamping voltage (VC) of 93 V at rated peak pulse current. This 35 V differential defines the overvoltage headroom available to protected ICs-ensuring downstream components rated for ≥100 V withstand worst-case surge events without failure.
What is the thermal resistance of SMCG58CA-M3/57T under standard mounting conditions?
SMCG58CA-M3/57T exhibits a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. This value is critical for derating peak pulse power above 25 °C ambient and must be used with Fig. 2 from the Vishay datasheet (Doc. #88457) to determine safe operating limits.
Does SMCG58CA-M3/57T require polarity marking on the PCB?
No-SMCG58CA-M3/57T is a bidirectional device with symmetrical anode/cathode terminals and no polarity marking on the package. PCB layout requires no orientation constraint, simplifying automated placement and reducing assembly errors compared to unidirectional TVS diodes like SMCG58A-M3/57T.
