Product details
Overview
SMCG16CA-M3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) surface-mount package, designed for clamping ESD and surge transients on signal/power lines. It features a 16 V stand-off voltage (VWM), 17.8–19.7 V breakdown voltage (VBR), 1500 W peak pulse power (PPPM), and clamps to ≤26.0 V at 57.7 A (10/1000 µs waveform), making it suitable for automotive sensor line protection per AEC-Q101.
For engineers reviewing the SMCG16CA-M3/57T datasheet, SMCG16CA-M3/57T pinout, SMCG16CA-M3/57T application, or SMCG16CA-M3/57T equivalent, this device delivers verified bidirectional clamping performance, halogen-free RoHS compliance, MSL Level 1 moisture sensitivity, and validated thermal resistance (RθJA = 75 °C/W) for high-reliability industrial and automotive PCB designs.
Technical Context
This TVS operates symmetrically in both directions due to its bidirectional construction, with no polarity marking required. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, enabling consistent clamping under repetitive 10/1000 µs surges up to 1500 W.
Thermally, it sustains operation from –55 °C to +150 °C junction temperature and dissipates 6.5 W continuously at TA = 50 °C on an infinite heatsink. The DO-215AB package provides robust mechanical mounting and meets UL 94 V-0 flammability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - Maximum continuous reverse operating voltage before clamping begins; defines safe signal line operating margin. |
| VBR min/max | 17.8 V / 19.7 V - Breakdown occurs within this range at 1 mA test current; ensures predictable turn-on across production lots. |
| VC @ IPPM | ≤26.0 V at 57.7 A - Clamped voltage during 10/1000 µs surge; protects downstream ICs rated for ≤30 V absolute maximum. |
| PPPM | 1500 W - Peak pulse power handling capability; supports IEC 61000-4-5 Level 4 (4 kV/2 Ω) surge immunity testing. |
| ID @ VWM | ≤1.0 µA - Reverse leakage at stand-off voltage; negligible loading on high-impedance sensor or communication lines. |
| TJ max | +150 °C - Maximum junction temperature rating; enables use in under-hood automotive environments. |
| RθJA | 75 °C/W - Junction-to-ambient thermal resistance on standard 8 mm × 8 mm copper pads; informs board-level thermal design. |
Pinout & Package
Package: SMCG (DO-215AB) - surface-mount, gull-wing leaded, halogen-free, RoHS-compliant, MSL Level 1, UL 94 V-0 molded compound. No polarity marking for bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (positive half-cycle) | One terminal of symmetrical junction; accepts surge current in either direction without polarity constraint. |

Applications
| Automotive Sensor Protection | Industrial CAN Bus Lines |
|---|---|
|
Use Scenario: Protecting LIN/CAN transceiver I/O pins and analog sensor outputs (e.g., pressure, temperature) in engine control units against load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector interface to shunt transients before reaching PHY layer. Use Value: Maintains signal integrity below 26.0 V clamp while surviving 1500 W surges-enabling compliance with ISO 16750-2 Class III/IV stress tests. |
Use Scenario: Safeguarding differential CAN_H/CAN_L lines in factory automation gateways exposed to motor drive switching noise and ESD events. IC Role / Device Role / Timing Role: Symmetric transient suppressor across differential pair, preserving common-mode rejection and bus timing margins. Use Value: Sub-1 µs response time and ≤1.0 µA leakage at 16 V VWM prevent false triggering and signal attenuation on 1 Mbps CAN FD links. |
| Consumer USB Interface Protection | Telecom Power Rail Clamping |
|
Use Scenario: Shielding USB 2.0 D+/D− lines in smart home hubs from human-body-model (HBM) ESD and cable-induced surges. IC Role / Device Role / Timing Role: Low-capacitance bidirectional TVS placed adjacent to connector to minimize stub length and preserve signal rise/fall times. Use Value: 16 V VWM aligns with 5 V USB supply rails; clamping <26 V prevents damage to USB PHY transceivers rated for 30 V abs max. |
Use Scenario: Suppressing lightning-induced surges on 24 V DC telecom power inputs feeding base station backhaul modules. IC Role / Device Role / Timing Role: Primary surge suppression stage upstream of DC/DC converters and LDOs to limit input rail overshoot. Use Value: 1500 W PPPM rating handles 10/1000 µs surges up to 4 kV (2 Ω source), reducing need for multi-stage protection networks. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16CA-E3/57T | Same VWM (16 V) and PPPM (400 W), but lower power rating; SMA (DO-214AC) package with higher RθJA (110 °C/W). | Limited to lower-energy transients (IEC 61000-4-2 Level 3); unsuitable for IEC 61000-4-5 Level 4 or automotive load dump. | Select when cost-sensitive consumer designs require basic ESD protection without automotive qualification. |
| SMCJ16CA-M3/57T | Identical VWM (16 V), higher PPPM (1500 W), same DO-214AB package footprint but larger body; RθJA = 65 °C/W. | Better thermal performance and higher IFSM (200 A vs. 100 A), but requires more PCB area and lacks AEC-Q101 certification. | Choose for industrial power supplies needing higher surge margin where automotive qualification is not mandated. |
Compared with SMAJ16CA-E3/57T and SMCJ16CA-M3/57T, the SMCG16CA-M3/57T uniquely combines AEC-Q101 qualification, DO-215AB compactness, and full 1500 W surge capability-making it the optimal choice for space-constrained automotive and industrial modules requiring certified reliability.

FAQ
What is the clamping voltage of SMCG16CA-M3/57T at its rated peak pulse current?
The SMCG16CA-M3/57T clamps to a maximum of 26.0 V at its specified peak pulse current of 57.7 A under the 10/1000 µs waveform condition. This value is measured per ANSI/IEEE C62.35 and guarantees protection for downstream components with ≤30 V absolute maximum ratings. The SMCG16CA-M3/57T achieves this with low incremental surge resistance, ensuring minimal voltage overshoot during fast transients.
Is SMCG16CA-M3/57T suitable for automotive applications?
Yes, SMCG16CA-M3/57T is AEC-Q101 qualified and specifically designed for automotive use, including engine control units, ADAS sensor interfaces, and infotainment system I/O protection. Its guaranteed operation from –55 °C to +150 °C, validated surge endurance, and halogen-free M3 construction meet stringent automotive reliability and environmental requirements. The SMCG16CA-M3/57T has passed temperature cycling, HTRB, and surge life testing per AEC-Q101 Rev G.
What does the "CA" suffix indicate in SMCG16CA-M3/57T?
The "CA" suffix in SMCG16CA-M3/57T denotes a bidirectional transient voltage suppressor configuration, meaning the device provides symmetrical clamping in both polarities without cathode band marking. This distinguishes it from unidirectional variants (e.g., SMCG16A), which require polarity-aware placement. The SMCG16CA-M3/57T applies identical electrical characteristics-VBR, VC, and PPPM-in both directions, simplifying layout for differential or AC-coupled signal lines.
How does the SMCG16CA-M3/57T package compare to SMAJ or SMCJ equivalents?
The SMCG16CA-M3/57T uses the DO-215AB (SMCG) package-smaller than SMCJ's DO-214AB and slightly larger than SMAJ's DO-214AC-with optimized thermal pad layout (8 mm × 8 mm copper per terminal). Its RθJA is 75 °C/W, between SMAJ (110 °C/W) and SMCJ (65 °C/W). Unlike SMAJ16CA-E3/57T, the SMCG16CA-M3/57T is AEC-Q101 qualified; unlike SMCJ16CA-M3/57T, it offers smaller footprint without sacrificing 1500 W PPPM rating.
What is the maximum reverse leakage current for SMCG16CA-M3/57T at its stand-off voltage?
The maximum reverse leakage current (ID) for SMCG16CA-M3/57T is 1.0 µA at its 16 V stand-off voltage (VWM) and TA = 25 °C. This ultra-low leakage ensures minimal loading on high-impedance sensor outputs, analog front-ends, or battery-powered circuits. The SMCG16CA-M3/57T maintains this specification across its full operating temperature range, supporting precision measurement and low-power design requirements.
