Product details
Overview
SMCG13CA-E3/57T from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in the SMCG (DO-215AB) surface-mount package, designed for clamping fast-rising ESD and surge transients. It features a 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR) at 1 mA, 1500 W peak pulse power (10/1000 µs), 69.8 A peak pulse current (IPPM), and clamps to ≤21.5 V at rated surge. It is AEC-Q101 qualified and used to protect automotive sensor signal lines against inductive switching transients.
For engineers reviewing the SMCG13CA-E3/57T datasheet, SMCG13CA-E3/57T pinout, SMCG13CA-E3/57T application, or SMCG13CA-E3/57T equivalent, key selection criteria include bidirectional clamping capability, 1500 W surge rating, DO-215AB thermal performance (RθJA = 75 °C/W), AEC-Q101 qualification, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical VBR min/max (14.4–15.9 V), ID ≤1.0 µA at VWM = 13 V, and VC ≤21.5 V at IPPM = 69.8 A under 10/1000 µs waveform. Its glass-passivated junction ensures stable breakdown and low leakage over temperature.
Designed for high-reliability automotive environments, it meets MSL Level 1 (260 °C reflow), JESD201 Class 2 whisker resistance, and UL 497B recognition (QVGQ2). The SMCG package provides low incremental surge resistance and excellent clamping response time <1 ns - critical for protecting CAN, LIN, and analog sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - maximum continuous reverse operating voltage before clamping begins; sets system-level signal integrity margin. |
| VBR (min/max) | 14.4 V / 15.9 V at IT = 1 mA - defines precise breakdown threshold for predictable transient initiation. |
| VC @ IPPM | ≤21.5 V at 69.8 A (10/1000 µs) - clamping voltage directly limits stress on downstream ICs like microcontrollers or ADCs. |
| PPPM | 1500 W - peak surge energy handling capacity determines suitability for ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 Level 4 compliance. |
| ID @ VWM | ≤1.0 µA - ultra-low leakage preserves battery life and avoids false triggering in low-power sensor nodes. |
| TJ max | +150 °C - enables operation in under-hood automotive locations without derating below full power. |
| RθJA | 75 °C/W - thermal resistance measured on 8.0 mm × 8.0 mm copper pads; informs PCB thermal design for sustained surge duty cycles. |
Pinout & Package
SMCG13CA-E3/57T uses the SMCG (DO-215AB) surface-mount package: gull-wing leads, matte tin-plated terminals, 0.220–0.245 inch body length, 0.115–0.125 inch width, and 0.024–0.040 inch height. No polarity marking on bidirectional variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (positive half-cycle) | Accepts surge current during positive voltage excursions; connects to protected line (e.g., CAN_H). |
| Cathode | Transient current entry (negative half-cycle) | Accepts surge current during negative voltage excursions; symmetrical role to Anode in bidirectional operation. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or differential signal lines (e.g., CAN, RS-485) without polarity concerns. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and surge endurance - required for Tier-1 ECU designs. |
| Glass passivated junction | Ensures stable VBR over lifetime and immunity to humidity-induced parameter drift in harsh under-hood environments. |
| MSL Level 1 rating | Supports standard SMT reflow profiles up to 260 °C peak without moisture-related popcorning or delamination. |
| UL 497B recognition (QVGQ2) | Confirms compliance with telecom and industrial surge protector safety standards - simplifies end-equipment certification. |
Applications

Use Scenario: Protecting microcontroller GPIOs driving brushed DC motor H-bridges in washing machines and HVAC blowers. IC Role / Device Role / Timing Role: Bidirectional clamp across motor driver supply rails and control lines. Use Value: Absorbs inductive flyback energy from motor commutation without polarity constraints, enabling compact dual-rail layout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13CA | Same VWM (13 V) and bidirectional configuration, but SMA (DO-214AC) package; lower PPPM (400 W); RθJA = 110 °C/W. | Limited to lower-energy transients (IEC 61000-4-2 only); unsuitable for ISO 7637-2 Pulse 5a or high-duty-cycle industrial surges. | Select when board space allows larger SMA footprint and surge requirements are ≤400 W. |
| 1.5KE13CA | Through-hole DO-201 package; same VWM/VBR specs; higher PPPM (1500 W); RθJA ≈ 25 °C/W on large heatsink. | Requires through-hole assembly and heatsinking; incompatible with fully SMT production; better for prototyping or low-volume power supplies. | Choose only if THT assembly is acceptable and thermal management via heatsink is feasible. |
Compared with SMAJ13CA and 1.5KE13CA, SMCG13CA-E3/57T delivers identical 13 V clamping performance in a smaller, AEC-Q101-qualified SMT package optimized for automotive and high-density industrial PCBs - enabling direct replacement where 1500 W surge handling and MSL-1 reflow are mandatory.

FAQ
What is the clamping voltage of SMCG13CA-E3/57T at its rated peak pulse current?
The SMCG13CA-E3/57T clamps to a maximum of 21.5 V at its rated peak pulse current (IPPM) of 69.8 A under the standardized 10/1000 µs waveform. This value is guaranteed across temperature and ensures downstream ICs such as automotive MCUs remain within safe operating voltage limits during surge events. The clamping behavior is symmetric for both polarities due to its bidirectional construction.
Is SMCG13CA-E3/57T suitable for automotive applications requiring AEC-Q101 qualification?
Yes, SMCG13CA-E3/57T is explicitly AEC-Q101 qualified, as confirmed in Vishay's official documentation (Document Number 88457, Revision 09-Jan-2024). This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and surge endurance - making SMCG13CA-E3/57T appropriate for under-hood and chassis-mounted automotive ECUs, sensor modules, and body control units.
What does the "CA" suffix indicate in SMCG13CA-E3/57T?
The "CA" suffix in SMCG13CA-E3/57T denotes a bidirectional transient voltage suppressor configuration. Unlike unidirectional variants (e.g., SMCG13A), the CA version provides symmetrical clamping for both positive and negative voltage transients - essential for protecting AC-coupled, differential, or floating signal lines such as CAN, LIN, or analog sensor outputs without polarity constraints.
What is the thermal resistance junction-to-ambient (RθJA) for SMCG13CA-E3/57T?
The typical thermal resistance junction-to-ambient (RθJA) for SMCG13CA-E3/57T is 75 °C/W, measured on the recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pad layout per terminal. This value guides PCB thermal design for sustained surge duty cycles and confirms the device can dissipate 6.5 W continuously at TA = 50 °C without exceeding its 150 °C maximum junction temperature.
How does the SMCG (DO-215AB) package differ from SMA (DO-214AC) in terms of surge handling?
The SMCG (DO-215AB) package used by SMCG13CA-E3/57T offers lower thermal resistance (RθJA = 75 °C/W vs. ~110 °C/W for SMAJ13CA) and higher power density than SMA, enabling full 1500 W peak pulse power dissipation in a compact gull-wing SMT form factor. Its wider copper pad footprint improves heat spreading, making SMCG13CA-E3/57T more effective for repetitive surge scenarios in automotive and industrial environments.
