Product details
Overview
SMCG16A-M3/57T from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor (TVS) in DO-215AB (SMCG) package, with 16 V stand-off voltage (VWM), 17.8–19.7 V breakdown voltage (VBR), 26.0 V clamping voltage (VC) at 57.7 A peak pulse current (IPPM), and 1500 W peak pulse power (PPPM). It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients in automotive and industrial power electronics.
For engineers reviewing the SMCG16A-M3/57T datasheet, SMCG16A-M3/57T pinout, SMCG16A-M3/57T application, or SMCG16A-M3/57T equivalent, this device is selected for high-energy surge immunity in 12 V/24 V DC systems where AEC-Q101 qualification, low incremental surge resistance, and fast response time (<1 ns) are required.
Technical Context
The SMCG16A-M3/57T uses an avalanche diode structure with glass-passivated junction to achieve sub-nanosecond response to ESD and lightning-induced surges. Its bidirectional counterpart is SMCG16CA; this variant is unidirectional, with cathode marked by band and polarity critical for correct placement in DC-biased protection paths.
Designed for mounting on 8.0 mm × 8.0 mm copper pads per terminal, it delivers 1500 W peak pulse power under 10/1000 µs waveform while maintaining thermal resistance of 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-lead), enabling reliable operation up to TJ = 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 16 V - Maximum continuous reverse operating voltage before clamping begins; sets threshold for protection in 12 V automotive systems. |
| VBR min/max | 17.8 V / 19.7 V - Breakdown occurs within this range at 1 mA test current; ensures consistent turn-on across production lots. |
| VC @ IPPM | 26.0 V - Clamped voltage at 57.7 A peak pulse current; limits stress on downstream 30 V-rated MOSFETs or logic ICs. |
| PPPM | 1500 W - Peak pulse power handling under 10/1000 µs waveform; supports IEC 61000-4-5 Level 4 surge immunity. |
| ID @ VWM | 1.0 µA - Reverse leakage at stand-off voltage; negligible power loss in always-on protection circuits. |
| TJ max | +150 °C - Maximum junction temperature; enables use in under-hood automotive environments without derating. |
| Package | DO-215AB (SMCG) - Low-profile SMD outline with gull-wing leads; compatible with automated reflow assembly and meets MSL level 1. |
Pinout & Package
SMCG16A-M3/57T is housed in the DO-215AB (SMCG) surface-mount package: gull-wing leads, matte tin-plated terminals, RoHS-compliant and halogen-free (M3 suffix), with cathode identified by a band on the case. Mounting requires 8.0 mm × 8.0 mm copper pads per terminal per Vishay's recommended layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to circuit ground or low-voltage rail; forms return path during transient conduction. |
| Cathode | Protected line input | Connected to line being protected (e.g., 12 V supply or sensor output); marked by band on case. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and body electronics per stress-test requirements. |
| 1500 W peak pulse power | Withstands IEC 61000-4-5 combination wave surges up to 4 kV/2 Ω without degradation. |
| Fast response time | <1 ns turn-on enables protection of high-speed interfaces like CAN FD and LIN bus transceivers. |
| Low incremental surge resistance | Minimizes voltage overshoot during high di/dt events, reducing risk of secondary overstress in protected ICs. |

Applications
| Automotive Power Distribution | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V supply rails feeding ECUs, lighting modules, and motor drivers from load-dump and jump-start transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery rail and local regulator input to clamp surges above 16 V. Use Value: Limits peak voltage to 26.0 V during 1500 W surges, preventing damage to 30 V-input LDOs and microcontrollers. |

IC Role / Device Role / Timing Role: TVS mounted at sensor connector to shunt induced transients before reaching precision ADC front-end. Use Value: 1.0 µA leakage at 16 V ensures no measurable offset error in mV-level sensor signals. |
| DC Motor Drive Gate Protection | Telecom Power Supply Input |
Use Scenario: Shielding high-side N-channel MOSFET gate drivers from inductive kickback during PWM commutation. IC Role / Device Role / Timing Role: TVS placed between gate driver output and MOSFET gate to clamp negative-going spikes below -0.7 V. Use Value: Sub-ns response prevents gate oxide breakdown in 40 V-rated logic-level MOSFETs exposed to >100 V/µs dv/dt. |
Use Scenario: Front-end surge suppression on 48 V telecom rectifier inputs subjected to lightning-induced surges. IC Role / Device Role / Timing Role: First-stage TVS in multi-stage protection network, absorbing bulk energy before MOV and GDT stages. Use Value: 1500 W rating allows single-device handling of 10/1000 µs surges up to 4 kV, simplifying BOM count. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ16A-E3/57T | Same VWM (16 V) and VC (26.0 V), but lower PPPM (400 W) and smaller SMA package (DO-214AC). | Not suitable for IEC 61000-4-5 Level 4; limited to consumer-grade 12 V systems with lower surge exposure. | Select when board space is constrained and surge threat level is ≤ Level 2. |
| SMCJ16A-M3/57T | Same VWM (16 V), higher PPPM (1500 W), identical DO-214AB package but larger footprint than SMCG. | Higher thermal mass improves sustained surge handling but requires more PCB area; not AEC-Q101 qualified. | Choose for industrial power supplies needing same power rating without automotive qualification. |
Compared with SMAJ16A-E3/57T and SMCJ16A-M3/57T, the SMCG16A-M3/57T uniquely combines AEC-Q101 qualification, 1500 W surge capability, and compact DO-215AB footprint-making it optimal for space-constrained automotive modules requiring full Level 4 compliance.

FAQ
What is the clamping voltage of SMCG16A-M3/57T and how does it protect downstream components?
The SMCG16A-M3/57T has a maximum clamping voltage (VC) of 26.0 V at 57.7 A peak pulse current. This ensures that during a 1500 W transient event, the voltage seen by protected components-such as 30 V-rated MOSFETs or microcontrollers-never exceeds 26.0 V. The low incremental surge resistance further minimizes overshoot, making SMCG16A-M3/57T effective for safeguarding sensitive nodes in 12 V automotive systems.
Is SMCG16A-M3/57T suitable for bidirectional signal line protection?
No, SMCG16A-M3/57T is a unidirectional TVS diode, intended for DC-biased applications such as power rail protection. For bidirectional signal lines (e.g., CAN, USB, or RS-485), the bidirectional variant SMCG16CA must be used instead. The SMCG16A-M3/57T features a cathode band marking and conducts only in reverse bias above VBR-using it on AC or floating lines risks failure or improper clamping.
What does the "M3" suffix mean in SMCG16A-M3/57T?
The "M3" suffix in SMCG16A-M3/57T indicates halogen-free, RoHS-compliant construction with matte tin-plated leads meeting JESD201 Class 2 whisker resistance. It also confirms industrial-grade qualification and compatibility with lead-free reflow profiles up to 260 °C peak. This distinguishes it from "E3" (standard RoHS) and "HM3" (AEC-Q101 + halogen-free) variants.
How does SMCG16A-M3/57T compare to SMAJ16A in terms of surge handling?
SMCG16A-M3/57T delivers 1500 W peak pulse power under 10/1000 µs waveform, whereas SMAJ16A is rated for only 400 W. Both share 16 V VWM and 26.0 V VC, but the SMCG16A-M3/57T's larger DO-215AB package and optimized thermal path enable triple the energy absorption. This makes SMCG16A-M3/57T appropriate for automotive load-dump events where SMAJ16A would fail catastrophically.
Can SMCG16A-M3/57T be used in place of SMCG16CA in a circuit?
No-SMCG16A-M3/57T is unidirectional and cannot replace SMCG16CA, which is bidirectional and symmetrical. Substituting SMCG16A-M3/57T in a bidirectional application (e.g., data line protection) will result in forward conduction during one half-cycle, causing short-circuit behavior and potential damage. Always match polarity: SMCG16A-M3/57T for DC rails, SMCG16CA for AC or floating lines.
