Product details
Overview
SMCG150CAHE3/57T 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), 150 V stand-off voltage (VWM), and clamping voltage of 243 V at 6.2 A peak pulse current. It is AEC-Q101 qualified and used to protect automotive sensor signal lines, power rails, and interface circuits against inductive switching transients and ESD.
For engineers reviewing the SMCG150CAHE3/57T datasheet, SMCG150CAHE3/57T pinout, SMCG150CAHE3/57T application, or SMCG150CAHE3/57T equivalent, this page delivers verified electrical parameters, mechanical package data, real-world protection use cases, and validated alternative parts - all aligned to Vishay's 88457 specification revision (Jan 2024).
Technical Context
The SMCG150CAHE3/57T operates as a bidirectional avalanche diode with symmetrical breakdown characteristics: minimum VBR = 167 V and maximum VBR = 185 V at 1 mA test current, enabling consistent clamping in both polarities. Its glass-passivated junction ensures stable leakage performance (<1.0 µA at VWM = 150 V) and fast response time (<1 ns) to transient events.
Thermally, it features RθJA = 75 °C/W and RθJL = 15 °C/W, supporting reliable operation up to TJ = +150 °C. The device meets J-STD-020 MSL Level 1 (260 °C peak reflow) and is rated for non-repetitive 8.3 ms surge currents up to 200 A in unidirectional configurations - though bidirectional operation limits IFSM applicability per datasheet note.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 µs) | 1500 W - sustains high-energy surges without failure under standardized lightning/inductive transient waveforms |
| Stand-Off Voltage (VWM) | 150 V - maximum continuous reverse operating voltage before significant leakage begins |
| Breakdown Voltage (VBR) | 167–185 V at 1 mA - defines the onset of avalanche conduction in both directions |
| Clamping Voltage (VC) | 243 V at IPPM = 6.2 A - maximum voltage seen across terminals during specified surge event |
| Peak Pulse Current (IPPM) | 6.2 A - surge current corresponding to VC = 243 V under 10/1000 µs waveform |
| Reverse Leakage (ID) | <1.0 µA at 150 V - ensures minimal power loss and signal integrity in standby conditions |
| Junction Temperature Range | −55 °C to +150 °C - supports automotive under-hood and industrial ambient environments |
Pinout & Package
Package: SMCG (DO-215AB) - low-profile, gull-wing surface-mount case with matte tin-plated leads, UL 94 V-0 molding compound, and AEC-Q101 qualification. No polarity marking on bidirectional variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Low incremental surge resistance | Enables tighter clamping (VC/VBR ratio ≈ 1.46) versus standard TVS diodes, reducing protected circuit stress |
| MSL Level 1 rating | Allows single-reflow assembly without moisture sensitivity concerns - compatible with standard SMT processes |
| UL 497B recognition (QVGQ2) | Meets Underwriters Laboratories requirements for telecom and industrial surge protector classification |
Applications
| Automotive Sensor Protection | Industrial CAN Bus Lines |
|---|---|
Use Scenario: Protecting ABS wheel speed sensor outputs from load-dump and alternator ripple transients in 12 V vehicle systems. IC Role / Device Role / Timing Role: Bidirectional clamping element placed across differential signal pair upstream of receiver IC.

Use Value: Withstands repetitive 1500 W pulses at 10/1000 µs, eliminating need for snubber RC networks and saving PCB area. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ150CA | Same VWM (150 V) and PPPM (400 W), but lower power rating and DO-214AC package | Limited to lower-energy transients; not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification and 1500 W surge margin |
| SMCJ150CA | Identical VWM (150 V), higher PPPM (1500 W), same DO-214AB package but larger footprint than SMCG | Requires more PCB area; same clamping performance (VC = 243 V) but slower thermal response due to higher RθJA | Choose if existing layout uses SMC package and board space permits 2.5× larger footprint |
Compared with SMAJ150CA and SMCJ150CA, the SMCG150CAHE3/57T delivers AEC-Q101 compliance and DO-215AB miniaturization without sacrificing 1500 W surge capability - making it optimal for space-constrained automotive and industrial modules where qualification and footprint matter.

FAQ
What is the clamping voltage of SMCG150CAHE3/57T at its rated peak pulse current?
The SMCG150CAHE3/57T has a maximum clamping voltage (VC) of 243 V at its specified peak pulse current (IPPM) of 6.2 A under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in Vishay's Document Number 88457, ensuring predictable overvoltage limiting during surge events.
Is SMCG150CAHE3/57T suitable for automotive applications?
Yes, SMCG150CAHE3/57T is AEC-Q101 qualified and explicitly listed in Vishay's qualification documentation for automotive use. Its −55 °C to +150 °C operating range, MSL Level 1 reflow compatibility, and UL 497B recognition make it appropriate for engine control units, ADAS sensors, and body electronics where transient immunity is critical.
Does SMCG150CAHE3/57T have polarity markings?
No, SMCG150CAHE3/57T is a bidirectional TVS diode and carries no cathode band or polarity marking. Its symmetrical construction ensures identical breakdown and clamping behavior in both directions - a key design feature confirmed in the "Polarity" section of Vishay's 88457 datasheet.
What is the thermal resistance of SMCG150CAHE3/57T?
The SMCG150CAHE3/57T 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″ copper pad layout. These values are essential for calculating safe power derating above 25 °C ambient, as shown in Figure 2 of the datasheet.
How does SMCG150CAHE3/57T differ from unidirectional SMCG150A variants?
Unlike unidirectional SMCG150A, the SMCG150CAHE3/57T provides symmetrical breakdown (VBR = 167–185 V in both directions) and omits cathode marking. It also excludes IFSM (200 A) rating - which applies only to unidirectional types - and is optimized for AC-coupled or differential signal protection where polarity reversal occurs.
