Product details
Overview
SMCG5.0CA-E3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) package, designed for robust overvoltage protection of sensitive electronics. It features a 5.0 V stand-off voltage (VWM), 6.40–7.25 V breakdown voltage (VBR), 1500 W peak pulse power (PPPM), and clamps transients to ≤9.20 V at 163 A (10/1000 μs waveform), making it suitable for automotive sensor signal-line protection.
For engineers reviewing the SMCG5.0CA-E3/57T datasheet, SMCG5.0CA-E3/57T pinout, SMCG5.0CA-E3/57T application, or SMCG5.0CA-E3/57T equivalent, this device is evaluated for AEC-Q101 qualified surge suppression in bidirectional DC circuits where low clamping voltage, fast response (<1 ns), and MSL Level 1 reflow compatibility are critical selection criteria.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical electrical characteristics in forward and reverse directions per ANSI/IEEE C62.35. Its glass-passivated junction ensures stable VBR and low leakage (≤1000 μA at VWM), while the DO-215AB package enables automated placement and meets UL 94 V-0 flammability requirements.
The device delivers 1500 W peak pulse power handling under standardized 10/1000 μs surges, with thermal resistance RθJA = 75 °C/W and RθJL = 15 °C/W. It is rated for continuous operation from –55 °C to +150 °C junction temperature and supports surge currents up to 163 A without degradation when mounted on 8.0 mm × 8.0 mm copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse/forward voltage before clamping begins; defines operating margin for 5 V logic/sensor lines. |
| VBR min/max | 6.40 V / 7.25 V - Breakdown occurs within this range at 10 mA test current; ensures reliable triggering above normal operating voltage. |
| VC @ IPPM | 9.20 V at 163 A - Clamped voltage during full-rated surge; limits stress on downstream ICs like microcontrollers or CAN transceivers. |
| PPPM | 1500 W - Peak transient energy absorption capability under 10/1000 μs waveform; supports IEC 61000-4-5 Level 4 immunity. |
| ID @ VWM | ≤1000 μA - Reverse leakage at stand-off voltage; low enough to avoid loading 5 V supply rails or high-impedance sensor inputs. |
| TJ max | +150 °C - Maximum junction temperature rating; enables use in under-hood automotive environments and industrial enclosures. |
| MSL Level | Level 1 (per J-STD-020) - Supports standard SMT reflow profiles up to 260 °C peak without preconditioning. |
Pinout & Package
Package: SMCG (DO-215AB) - surface-mount, gull-wing leaded case with matte tin-plated terminals, 0.220–0.245 inch body length, 0.115–0.125 inch width, and 0.024–0.040 inch height. No polarity marking on bidirectional variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| UL 94 V-0 molding compound | Meets flame-retardancy requirements for enclosed automotive and industrial assemblies where fire safety compliance is mandatory. |
| MSL Level 1 rating | Enables direct placement into standard high-temperature reflow ovens (peak 260 °C) without baking or special handling protocols. |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting analog output lines (e.g., 0–5 V throttle position sensor signals) from load-dump and inductive switching transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector entry point to shunt surge energy before reaching ADC input or op-amp buffer. Use Value: Limits transient voltage to ≤9.20 V, preserving signal integrity and preventing latch-up in 5 V rail-tied sensor interface ICs. |
Use Scenario: Safeguarding 24 V DC digital input modules in programmable logic controllers against field-wiring ESD and relay-coil flyback spikes. IC Role / Device Role / Timing Role: Primary surge suppression device installed across input terminals upstream of optocoupler isolation barriers. Use Value: Absorbs 1500 W surges without degradation, enabling compliance with IEC 61000-4-4 (EFT) and IEC 61000-4-5 (surge) immunity standards. |
| Telecom Line Interface | Consumer USB Port Protection |
Use Scenario: Shielding RS-485 transceiver data lines in base station remote units exposed to lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: Low-capacitance (typ. <50 pF) bidirectional clamp placed differential-mode across A/B bus lines near connector. Use Value: Maintains signal fidelity at >10 Mbps due to sub-nanosecond response and symmetrical clamping behavior. |
Use Scenario: Adding secondary overvoltage protection on VBUS and D+/D− lines of USB 2.0 ports in smart home hubs subjected to hot-plug ESD events. IC Role / Device Role / Timing Role: Secondary TVS stage after primary polymer PTC, clamping fast-rising ESD pulses (IEC 61000-4-2 ±15 kV contact). Use Value: Achieves <1 ns response time and ≤9.20 V clamping, preventing damage to USB PHY transceivers rated for 5.5 V absolute maximum. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A-E3/57T | Unidirectional; same VWM/VBR/PPPM but asymmetric conduction; lower IPPM (158 A); SMA (DO-214AC) package. | Requires polarity-aware layout; unsuitable for AC or floating lines; smaller footprint but higher thermal resistance (RθJA = 110 °C/W). | Select only for unidirectional DC rails where space is constrained and polarity is fixed. |
| SMCJ5.0CA | Bidirectional; identical VWM/VBR/PPPM specs; same DO-215AB package; but non-AEC-Q101 rated and MSL Level 2. | Lacks automotive qualification; requires baking before reflow; intended for industrial/commercial use only. | Use where AEC-Q101 is not mandated and cost sensitivity outweighs qualification requirements. |
Compared with SMAJ5.0A-E3/57T and SMCJ5.0CA, the SMCG5.0CA-E3/57T uniquely combines bidirectional symmetry, AEC-Q101 qualification, and MSL Level 1 compatibility-making it the only choice for automotive-grade 5 V signal-line protection requiring zero-layout polarity dependency and drop-in reflow readiness.

FAQ
What is the clamping voltage of the SMCG5.0CA-E3/57T at its rated peak pulse current?
The SMCG5.0CA-E3/57T clamps to a maximum of 9.20 V at its rated peak pulse current of 163 A under the standardized 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and verified on the minimum recommended 8.0 mm × 8.0 mm copper pad layout. The low clamping voltage ensures downstream 5 V ICs remain within safe operating limits during surge events.
Is the SMCG5.0CA-E3/57T suitable for automotive applications?
Yes, the SMCG5.0CA-E3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood and chassis-mounted systems. Its –55 °C to +150 °C operating temperature range, MSL Level 1 reflow compatibility, and bidirectional symmetry make it appropriate for protecting CAN/LIN sensor lines, ADAS camera interfaces, and body control module I/O in production vehicles.
Does the SMCG5.0CA-E3/57T have polarity markings on the package?
No, the SMCG5.0CA-E3/57T has no polarity markings because it is a bidirectional TVS diode. Unlike unidirectional variants (e.g., SMCG5.0A), which feature a cathode band, the CA-suffix devices are symmetric and function identically regardless of terminal orientation-eliminating layout errors in AC-coupled or floating signal paths.
What is the thermal resistance of the SMCG5.0CA-E3/57T?
The SMCG5.0CA-E3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead resistance (RθJL) of 15 °C/W, measured on the recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pad layout. These values enable effective heat dissipation during repetitive surge events and support continuous operation at full rated power when properly mounted.
How does the SMCG5.0CA-E3/57T differ from the SMAJ5.0A-E3/57T?
The SMCG5.0CA-E3/57T is bidirectional with no polarity marking and AEC-Q101 qualification, while the SMAJ5.0A-E3/57T is unidirectional, requires cathode alignment, and lacks automotive qualification. Both share 5.0 V VWM and ~1500 W PPPM, but the SMCG5.0CA-E3/57T offers superior thermal performance (RθJA = 75 vs. 110 °C/W) and is optimized for automotive signal-line protection where layout flexibility and qualification are mandatory.
