Product details
Overview
SMCG36CA-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 on signal and power lines. It features a 36 V stand-off voltage (VWM), 40.0–44.2 V breakdown voltage (VBR), 1500 W peak pulse power (PPPM), and clamps to ≤58.1 V at 25.8 A (10/1000 µs waveform), making it suitable for automotive sensor interface and industrial I/O line protection.
For engineers reviewing the SMCG36CA-E3/57T datasheet, SMCG36CA-E3/57T pinout, SMCG36CA-E3/57T application, or SMCG36CA-E3/57T equivalent, key selection criteria include bidirectional clamping symmetry, AEC-Q101 qualification, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This device operates as a silicon avalanche diode with glass-passivated junction, delivering symmetrical clamping in both polarities due to its bidirectional construction. Its low incremental surge resistance and fast response time (<1 ns) enable effective suppression of ESD, lightning-induced transients, and inductive switching spikes.
The SMCG36CA-E3/57T is rated for TJ = –55 °C to +150 °C, exhibits 1.0 µA max reverse leakage at VWM, and maintains stable clamping performance across temperature when mounted per recommended pad layout - critical for automotive and industrial environments where thermal derating must be managed.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 36 V - Maximum continuous reverse operating voltage before clamping begins; defines safe working range for protected circuitry. |
| VBR min/max | 40.0 V / 44.2 V at 1.0 mA - Confirmed breakdown threshold ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | ≤58.1 V at 25.8 A (10/1000 µs) - Clamping voltage directly limits stress on downstream ICs like microcontrollers or transceivers. |
| PPPM | 1500 W - Peak transient energy handling capacity under standardized surge waveform; supports high-energy automotive load-dump immunity. |
| TJ max | +150 °C - Enables reliable operation in under-hood automotive or high-ambient industrial settings without thermal shutdown. |
| MSL Level | Level 1 (J-STD-020) - Allows unlimited floor life and reflow up to 260 °C peak, simplifying manufacturing flow. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including HTGB, HTRB, and temperature cycling per AEC stress test standards. |
Pinout & Package
Package: SMCG (DO-215AB) - surface-mount, low-profile gull-wing leaded package with matte tin-plated terminals, UL 94 V-0 molding compound, and polarity-unmarked for bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (positive polarity) | One terminal of symmetrical avalanche junction; accepts surge current in either direction. |
| Cathode | Transient current exit (negative polarity) | Second terminal of symmetrical junction; completes bidirectional conduction path with Anode. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR and VC characteristics in both directions - eliminates need for polarity-aware layout or orientation verification. |
| AEC-Q101 qualification | Validated for automotive electronics per stress tests including HTGB, HTRB, and temperature cycling - enables use in ADAS and body control modules. |
| Glass passivated junction | Enhanced long-term stability and reduced parameter drift under thermal cycling and humidity exposure - improves field reliability. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients - critical for protecting high-speed interfaces like CAN FD or LIN. |
| MSL Level 1 rating | Enables direct placement into reflow oven without baking - reduces production cost and avoids moisture-related popcorning failures. |
Applications
| Automotive Sensor Protection | Industrial I/O Interface |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ36CA | Same VWM/VBR/PPPM specs but SMA (DO-214AC) package; higher RθJA (110 °C/W vs. 75 °C/W). | Limited to lower-power or lower-duty-cycle surge events due to inferior thermal dissipation. | Select SMAJ36CA only if board space constraints prohibit DO-215AB footprint or if legacy SMA layout exists. |
| 1.5KE36CA | Through-hole TO-218 package; same electrical specs but 1.5 kW rating tested on larger heatsink; no AEC-Q101 qualification. | Not suitable for automotive or high-reliability industrial SMT production; requires wave soldering. | Choose 1.5KE36CA only for prototyping, repair, or non-automotive applications where AEC-Q101 is not mandated. |
Compared with SMAJ36CA and 1.5KE36CA, the SMCG36CA-E3/57T delivers superior thermal performance (RθJA = 75 °C/W), AEC-Q101 validation, and optimized SMT manufacturability - making it the preferred choice for volume automotive and industrial designs requiring long-term reliability and process scalability.
