Product details
Overview
SMCG150CA-E3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) in the SMCG (DO-215AB) package, designed for robust overvoltage protection of signal and power lines. It features a 150 V stand-off voltage (VWM), 167–185 V breakdown voltage (VBR), 1500 W peak pulse power (PPPM), and clamps to ≤243 V at 6.2 A IPPM under 10/1000 μs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMCG150CA-E3/57T datasheet, SMCG150CA-E3/57T pinout, SMCG150CA-E3/57T application, or SMCG150CA-E3/57T equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), DO-215AB mechanical outline, and direct alternatives for bidirectional TVS selection in high-reliability designs.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VBR min/max (167–185 V), ID ≤1.0 μA at VWM, and VC ≤243 V at rated IPPM. Its glass-passivated junction ensures stable leakage and low capacitance, while MSL Level 1 rating supports lead-free reflow up to 260 °C peak.
Designed for transient suppression per ANSI/IEEE C62.35, it handles non-repetitive 10/1000 μs surges without degradation when mounted on 8.0 mm × 8.0 mm copper pads. Junction temperature range spans −55 °C to +150 °C, and thermal resistance (RθJL = 15 °C/W) enables effective heat transfer to PCB traces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 150 V - maximum continuous reverse operating voltage before clamping initiates |
| VBR (min/max) | 167 V / 185 V - guaranteed breakdown threshold range at 1 mA test current |
| PPPM | 1500 W - peak surge power handling capability under standardized 10/1000 μs waveform |
| VC @ IPPM | ≤243 V at 6.2 A - clamping voltage during full-rated surge, defining protected circuit stress level |
| ID @ VWM | ≤1.0 μA - ultra-low leakage ensures minimal standby power loss and signal integrity |
| TJ max. | +150 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| RθJA | 75 °C/W - thermal resistance from junction to ambient on standard 8 mm × 8 mm pad layout |
Pinout & Package
Package: SMCG (DO-215AB) - surface-mount, low-profile gull-wing package 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 |
|---|---|---|
| Anode | Transient current entry (positive half-cycle) | One terminal of symmetrical junction; conducts during positive transients relative to cathode reference |
| Cathode | Transient current entry (negative half-cycle) | Second terminal of symmetrical junction; conducts during negative transients relative to anode reference |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional symmetry | Identical VBR, VC, and IPPM performance in both directions - eliminates polarity concerns in AC-coupled or floating lines |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD - suitable for engine control and ADAS sensor protection |
| Low incremental surge resistance | Enables tighter clamping (VC − VBR ≈ 76 V) versus competing TVS diodes - reduces voltage overshoot on protected ICs |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and compatibility with standard SMT reflow profiles up to 260 °C peak - no baking required pre-assembly |
| Glass passivated junction | Ensures stable leakage (<1 μA) and long-term parameter consistency across temperature and humidity stress |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ESD events in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector interface to shunt transients before reaching signal conditioning ICs. Use Value: With 150 V VWM and 243 V VC, it safeguards 12 V automotive electronics against ISO 7637-2 Pulse 5a (load dump) without false triggering. |
Use Scenario: Shielding digital input modules in programmable logic controllers from inductive kickback caused by relay/solenoid switching. IC Role / Device Role / Timing Role: Parallel-connected TVS on each 24 V DC input channel to clamp fast-rising transients (<1 ns rise time) before optocoupler inputs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ150CA | Same VWM (150 V) and PPPM (1500 W), but SMA (DO-214AC) package - larger footprint, higher RθJA (95 °C/W) | Limited to lower-power or less thermally constrained layouts; not AEC-Q101 qualified | Select when DO-215AB footprint is unavailable and AEC-Q101 compliance is not required |
| SMCJ150CA | Higher PPPM (1500 W same), but wider VBR range (167–197 V); SMC (DO-214AB) package with RθJA = 50 °C/W | Better thermal performance but larger body; requires more board area and different stencil design | Choose for higher thermal margin in high-ambient industrial enclosures where space permits |
Compared with SMCG150CA-E3/57T, SMAJ150CA offers identical electrical ratings but inferior thermal and automotive qualification; SMCJ150CA improves thermal dissipation at the cost of footprint size and assembly compatibility - SMCG150CA-E3/57T uniquely balances AEC-Q101 compliance, compact DO-215AB form factor, and proven surge robustness.

FAQ
What is the clamping voltage of SMCG150CA-E3/57T at its rated peak pulse current?
The SMCG150CA-E3/57T clamps to a maximum of 243 V at its rated peak pulse current (IPPM) of 6.2 A under the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in the Vishay datasheet revision 09-Jan-2024, ensuring predictable overvoltage limiting for downstream ICs in protected circuits.
Is SMCG150CA-E3/57T suitable for automotive applications?
Yes, SMCG150CA-E3/57T is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its −55 °C to +150 °C operating junction temperature range, MSL Level 1 reflow compatibility, and validated robustness against load dump and ESD make it appropriate for ECUs, ADAS sensors, and body control modules where SMCG150CA-E3/57T serves as primary transient protection.
Does SMCG150CA-E3/57T have polarity markings on the package?
No, SMCG150CA-E3/57T does not feature polarity markings because it is a bidirectional TVS diode. Unlike unidirectional types that use a cathode band, the SMCG150CA-E3/57T has symmetric electrical behavior in both directions - eliminating orientation constraints during automated placement and simplifying PCB layout for differential or floating signal lines.
What is the thermal resistance of SMCG150CA-E3/57T under standard mounting conditions?
Under the standard mounting condition of 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal, SMCG150CA-E3/57T exhibits a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-lead resistance (RθJL) of 15 °C/W. These values are specified in the Vishay datasheet and critical for calculating safe power derating above 25 °C ambient.
How does the SMCG150CA-E3/57T differ from the unidirectional SMCG150A-E3/57T?
The SMCG150CA-E3/57T is bidirectional with symmetrical VBR (167–185 V) and clamping in both polarities, while SMCG150A-E3/57T is unidirectional with cathode marking and forward conduction capability. Their VWM (150 V), PPPM (1500 W), and package (DO-215AB) match, but SMCG150CA-E3/57T replaces two unidirectional devices in AC or floating applications - reducing BOM count and layout complexity without sacrificing protection level.
