Product details
Overview
SMBG13CA-E3/52 from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMBG (DO-215AA) package, designed for robust overvoltage protection of signal and power lines. It features a 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 µs), clamping voltage of 21.5 V at 27.9 A, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMBG13CA-E3/52 datasheet, SMBG13CA-E3/52 pinout, SMBG13CA-E3/52 application, or SMBG13CA-E3/52 equivalent, key selection criteria include bidirectional surge clamping performance, junction temperature range (−55 °C to +150 °C), low leakage (<1.0 µA at VWM), RoHS-compliant matte tin terminations, and MSL Level 1 reflow compatibility up to 260 °C.
Technical Context
This bidirectional TVS operates symmetrically in both polarities, with identical VBR, IPPM, and VC specifications for positive and negative transients. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while the low incremental surge resistance supports effective energy diversion during ESD or lightning-induced surges.
The device is rated for 600 W peak pulse power under 10/1000 µs waveform at 0.01% duty cycle, derated linearly above 25 °C ambient per Fig. 2, and exhibits typical thermal resistance of 100 °C/W (junction-to-ambient) on 0.2" × 0.2" copper pads - critical for thermal management in compact automotive and industrial PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse operating voltage before clamping begins; defines safe signal line operating margin. |
| VBR (min/max) | 14.4 V / 15.9 V at 1 mA - Confirmed breakdown threshold range; ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 21.5 V at 27.9 A - Clamped voltage during 600 W surge; protects downstream ICs rated ≤20 V logic rails. |
| ID @ VWM | <1.0 µA - Ultra-low reverse leakage; avoids signal integrity degradation in high-impedance sensor interfaces. |
| PPPM | 600 W - Peak pulse power handling per 10/1000 µs waveform; meets IEC 61000-4-5 Level 4 surge immunity requirements. |
| TJ Range | −55 °C to +150 °C - Full automotive-grade junction temperature range; supports under-hood and engine-control module deployment. |
| MSL Level | Level 1 (J-STD-020) - No floor life limitation; compatible with standard SMT reflow profiles up to 260 °C peak. |
Pinout & Package
Package: SMBG (DO-215AA) surface-mount package with gull-wing leads, 0.235" × 0.130" footprint, 0.030" nominal lead thickness, and matte tin-plated terminations solderable per J-STD-002 and JESD 22-B102. Bidirectional construction has no polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity) | One terminal of symmetrical P-N junction; conducts during negative-going surges to clamp voltage. |
| Cathode | Transient current entry (positive polarity) | Other terminal of symmetrical P-N junction; conducts during positive-going surges to clamp voltage. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or differential signal lines (e.g., CAN, LIN, RS-485) without polarity concerns. |

| Low profile SMBG package | 0.030" height enables placement beneath connectors or in space-constrained modules such as battery management systems. |
Applications
| Automotive Power Line Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed microcontroller power rails from load-dump transients (ISO 16750-2) and alternator ripple. IC Role / Device Role / Timing Role: Primary clamping element placed at power entry point upstream of DC/DC converter input. Use Value: Limits voltage excursion to ≤21.5 V during 35 V/100 ms load dump, preventing damage to 24 V-rated regulators and MCU IOs. | Use Scenario: Safeguarding analog outputs (e.g., 4–20 mA current loop drivers) in factory automation PLC I/O modules. IC Role / Device Role / Timing Role: Bidirectional shunt protector across output terminals to absorb field-wiring induced surges. Use Value: Maintains signal fidelity with <1 µA leakage at 13 V, while clamping 1 kV/0.5 A transients within 1 ns to preserve loop accuracy. |
| Automotive CAN Bus Protection | Consumer USB Port ESD Protection |
Use Scenario: Shielding high-speed CAN FD transceivers (e.g., TJA1044) against ESD (IEC 61000-4-2 ±15 kV) and ISO 7637-3 coupled pulses. IC Role / Device Role / Timing Role: Low-capacitance bidirectional TVS placed directly at connector pins, adjacent to common-mode choke. Use Value: Clamps transients to 21.5 V without distorting 5 Mbps CAN signals due to absence of polarity marking and minimal parasitic capacitance. | Use Scenario: Hardening USB 2.0 D+/D− lines in automotive infotainment head units against hot-plug ESD and cable discharge events. IC Role / Device Role / Timing Role: Symmetric shunt suppressor bridging differential pair, leveraging bidirectional operation to handle both data line polarities. Use Value: Provides ±15 kV contact ESD protection per IEC 61000-4-2 while adding <0.5 pF capacitance - negligible impact on signal rise/fall times. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA-E3/52 | Same VWM/VBR/VC, but 600 W rating uses 10/1000 µs waveform with 0.01% duty cycle; SMBJ has slightly larger DO-214AA package (0.295" × 0.165"). | SMBJ13CA offers higher thermal mass but requires larger PCB area; preferred where board space permits and higher IPPM margin is needed. | Select SMBG13CA-E3/52 when footprint minimization and AEC-Q101 compliance are mandatory; choose SMBJ13CA-E3/52 for legacy designs using DO-214AA footprints. |
| 1.5KE13CA | Higher 1500 W peak power (10/1000 µs), through-hole DO-201AD package, VC = 22.5 V at 65.2 A; not AEC-Q101 qualified. | Used in non-automotive industrial power supplies where manual assembly and higher surge margin outweigh SMT constraints. | Choose 1.5KE13CA only for cost-sensitive, non-automotive applications requiring higher single-pulse energy absorption and no reflow compatibility requirement. |
Compared with SMBJ13CA-E3/52 and 1.5KE13CA, SMBG13CA-E3/52 delivers optimal balance of automotive qualification, compact SMBG footprint, and verified 600 W surge capability - making it the preferred choice for space-constrained, high-reliability automotive and industrial SMT designs.

FAQ
What is the maximum clamping voltage of SMBG13CA-E3/52 under a 10/1000 µs surge?
The SMBG13CA-E3/52 clamps to a maximum of 21.5 V when subjected to its rated peak pulse current of 27.9 A (corresponding to 600 W with a 10/1000 µs waveform). This value is measured per Figure 1 in the Vishay datasheet 88456 and represents worst-case voltage seen by protected circuitry during standardized surge testing.
Is SMBG13CA-E3/52 suitable for protecting CAN FD bus lines?
Yes, SMBG13CA-E3/52 is suitable for CAN FD bus protection due to its bidirectional symmetry, 21.5 V clamping voltage (well below typical CAN transceiver absolute maximum ratings), sub-nanosecond response time, and AEC-Q101 qualification. Its low leakage (<1.0 µA) and absence of polarity marking simplify layout for differential signaling.
Does SMBG13CA-E3/52 have a marked cathode band?
No, SMBG13CA-E3/52 does not have a cathode band or any polarity marking because it is a bidirectional TVS diode. The device functions identically in both directions, with symmetrical electrical characteristics - unlike unidirectional variants such as SMBG13A-E3/52 which feature a visible band denoting the cathode end.
What is the junction-to-ambient thermal resistance (RθJA) of SMBG13CA-E3/52?
The typical junction-to-ambient thermal resistance (RθJA) of SMBG13CA-E3/52 is 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the Thermal Characteristics table of Vishay document 88456. This value assumes standard JEDEC test conditions and must be adjusted for actual PCB layout and copper area.
How does the RoHS compliance and MSL rating of SMBG13CA-E3/52 impact manufacturing?
SMBG13CA-E3/52 is RoHS compliant (per EU Directive 2011/65/EU) and rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and can withstand peak reflow temperatures up to 260 °C without baking. This simplifies SMT assembly, eliminates moisture sensitivity handling requirements, and supports high-yield automated placement in automotive and industrial production lines.
