Product details
Overview
SMCG160CA-E3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) package, designed for high-energy surge protection on signal and power lines. It features a 160 V stand-off voltage (VWM), 1500 W peak pulse power (PPPM), clamping voltage of 259 V at 5.8 A IPPM, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the SMCG160CA-E3/57T datasheet, SMCG160CA-E3/57T pinout, SMCG160CA-E3/57T application, or SMCG160CA-E3/57T equivalent, this device is selected for robust overvoltage protection in automotive sensor interfaces, industrial I/O ports, and telecom line cards where bidirectional clamping, low leakage (<1.0 µA at VWM), and MSL Level 1 reflow compatibility are critical.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with breakdown voltage (VBR) specified at 178–197 V (min/max) under 1 mA test current - ensuring consistent clamping behavior regardless of transient polarity. Its glass-passivated junction and low incremental surge resistance enable sub-nanosecond response to ESD and lightning-induced transients.
The device is rated for TJ = –55 °C to +150 °C operation, with thermal resistance RθJA = 75 °C/W and RθJL = 15 °C/W, supporting reliable performance on standard 8.0 mm × 8.0 mm copper pads. It meets UL 497B recognition (QVGQ2) and JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 160 V - maximum continuous reverse operating voltage before clamping begins |
| VBR (min/max) | 178 V / 197 V at IT = 1 mA - defines symmetric breakdown threshold in both directions |
| VC @ IPPM | 259 V at 5.8 A - clamped voltage during 10/1000 µs surge, limiting downstream stress |
| PPPM | 1500 W - peak power dissipation capability for standardized surge waveform |
| ID @ VWM | <1.0 µA - ultra-low leakage preserves signal integrity in high-impedance circuits |
| TJ max. | +150 °C - enables use in under-hood automotive and industrial environments |
| AEC-Q101 | Qualified - validated for automotive electronics per stress-test requirements |
Pinout & Package
Package: SMCG (DO-215AB) - surface-mount, low-profile gull-wing lead frame with matte tin-plated terminals, compliant with J-STD-002 and JESD22-B102 solderability standards. No polarity marking on bidirectional variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160A-E3/57T | Unidirectional; lower PPPM (400 W); SMA (DO-214AC) package; no AEC-Q101 qualification | Limited to DC-biased lines; unsuitable for AC or differential signals without external biasing | Select only for cost-sensitive, non-automotive DC applications where bidirectionality and 1500 W rating are unnecessary |
| SMCJ160CA | Same VWM/VC specs but in larger SMC (DO-214AB) package; higher thermal mass; identical AEC-Q101 status | Requires larger PCB area; better suited for high-repetition-rate surges due to improved heat dissipation | Choose when board space permits and thermal derating margin is critical - not a drop-in replacement due to footprint mismatch |
Compared with SMCG160CA-E3/57T, SMAJ160A-E3/57T offers lower surge capacity and unidirectional operation, while SMCJ160CA provides identical electrical performance in a thermally superior but physically larger package - making SMCG160CA-E3/57T optimal for space-constrained automotive and industrial designs requiring certified bidirectional clamping.

FAQ
What is the clamping voltage of SMCG160CA-E3/57T and how is it measured?
The clamping voltage (VC) of SMCG160CA-E3/57T is 259 V, measured at a peak pulse current (IPPM) of 5.8 A using the standardized 10/1000 µs double-exponential surge waveform. This value reflects the maximum voltage that appears across the device during a transient event, directly limiting stress on downstream components. The specification is verified per ANSI/IEEE C62.35 and applies identically in both directions due to its bidirectional construction.
Is SMCG160CA-E3/57T suitable for automotive applications?
Yes, SMCG160CA-E3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including engine control units, body electronics, and ADAS sensor interfaces. Its operating temperature range of –55 °C to +150 °C, MSL Level 1 reflow compatibility, and UL 497B recognition confirm suitability for under-hood and chassis-mounted systems where reliability under thermal and mechanical stress is mandatory.
How does the bidirectional design of SMCG160CA-E3/57T affect circuit layout?
The bidirectional design of SMCG160CA-E3/57T eliminates polarity marking and allows placement across any two nodes subject to differential or AC-coupled transients - such as CAN H/L lines or Ethernet pairs - without regard to orientation. Unlike unidirectional TVS diodes, it requires no external biasing or series diodes, simplifying layout and reducing component count in symmetric protection schemes.
What is the maximum leakage current of SMCG160CA-E3/57T at its stand-off voltage?
SMCG160CA-E3/57T exhibits a maximum reverse leakage current (ID) of 1.0 µA at its 160 V stand-off voltage (VWM), measured at TA = 25 °C. This ultra-low leakage preserves signal integrity in high-impedance sensor interfaces and ensures minimal power loss in always-on automotive subsystems - a key differentiator versus higher-leakage alternatives like standard Zener-based protectors.
Does SMCG160CA-E3/57T require special PCB layout considerations for thermal performance?
Yes - to achieve rated 1500 W peak pulse power, SMCG160CA-E3/57T must be mounted on minimum 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal, as specified in the Vishay datasheet. Smaller pads reduce thermal dissipation, causing premature thermal runaway during repeated surges. The device's RθJA of 75 °C/W assumes this layout; deviation requires derating per Figure 2 in document 88457.
