Product details
Overview
SMBJ10CA-13-F from Diodes Incorporated is a bi-directional 600W surface-mount transient voltage suppressor (TVS) diode with 10V reverse standoff voltage, 11.1V minimum breakdown voltage, and 17.0V maximum clamping voltage at 35.3A peak pulse current. It features glass-passivated die construction, SMB package, and RoHS-compliant lead-free plating, designed for overvoltage protection in DC power rails and I/O interfaces of industrial control systems.
For engineers reviewing the SMBJ10CA-13-F datasheet, SMBJ10CA-13-F pinout, SMBJ10CA-13-F application, or SMBJ10CA-13-F equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD, peak pulse current handling under 8.3ms surge, standoff voltage tolerance versus system operating voltage, and thermal derating above +25°C ambient.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, enabling robust ESD and lightning surge suppression on AC-coupled lines or ungrounded signal paths without polarity constraints. Its 17.0V clamping voltage ensures safe voltage limiting during 35.3A transients while maintaining <5.0μA leakage at 10V standoff.
The device uses a planar junction structure with glass passivation for stable avalanche characteristics and low capacitance (<100pF at 1MHz), making it suitable for high-speed data lines where signal integrity must be preserved during transient events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - Sustains single 8.3ms half-sine surges up to 35.3A without failure |
| Reverse Standoff Voltage | 10.0V - Maximum continuous DC or RMS voltage before significant leakage begins |
| Breakdown Voltage | 11.1–12.8V @ 1mA - Avalanche conduction initiates within this range to limit overvoltage |
| Clamping Voltage | 17.0V @ 35.3A - Limits transient voltage seen by downstream circuitry during worst-case surge |
| Leakage Current | 5.0μA @ 10V - Negligible standby power loss and minimal loading on protected supply rail |
| Operating Temperature | −55°C to +150°C - Supports deployment in automotive engine compartments and industrial enclosures |
Pinout & Package

Applications
| Industrial PLC I/O Protection | Automotive Body Control Module |
|---|---|
Use Scenario: 24V digital input channels exposed to load dump and inductive switching noise in programmable logic controllers. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed between field wiring and input buffer IC. Use Value: Clamps transients to ≤17.0V, keeping input voltage below absolute maximum rating of 30V-rated buffer ICs. |
Use Scenario: CAN transceiver power supply line (VCC) subjected to ISO 7637-2 Pulse 1 and Pulse 2a surges. IC Role / Device Role / Timing Role: Secondary protection stage after primary LC filter, absorbing residual energy not attenuated upstream. Use Value: Limits voltage excursion to 17.0V during 35.3A surge, preventing latch-up or damage to 5V CAN PHY ICs. |
| Telecom Power Feeds | Medical Diagnostic Equipment Interfaces |
Use Scenario: −48V DC power feed lines in remote radio units vulnerable to induced lightning surges. IC Role / Device Role / Timing Role: Bi-directional clamp on power rail referenced to chassis ground, protecting DC-DC converters. Use Value: Symmetric clamping ensures equal protection for positive and negative excursions, critical for negative-rail systems. |
Use Scenario: Analog sensor interface lines (e.g., thermistor, pressure transducer) connected to patient-connected modules. IC Role / Device Role / Timing Role: Low-leakage (5.0μA) transient suppressor placed directly at connector entry point. Use Value: Prevents ESD-induced offset drift in precision amplifiers while adding <100pF capacitance that does not degrade 1kHz signal bandwidth. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A-13-F | Uni-directional; cathode-banded; 5.0μA leakage same, but conducts only in reverse bias | Requires correct polarity placement; unsuitable for AC or floating circuits | Select only when protecting unidirectional DC rails with known polarity and no risk of reverse voltage exposure |
| SMAJ10CA-13-F | Same electrical specs but SMA package; 400W peak power rating vs. 600W | Lower surge capacity limits use to lower-energy threats (e.g., IEC 61000-4-2 ESD only) | Choose when board space is constrained and surge threat level is limited to Class 3 ESD or low-energy transients |
Compared with SMBJ10A-13-F, the bi-directional SMBJ10CA-13-F eliminates polarity dependency and enables universal placement, while compared with SMAJ10CA-13-F, its 600W rating provides 50% higher surge energy absorption in the same footprint-constrained SMB form factor.

FAQ
What is the difference between SMBJ10CA-13-F and SMBJ10A-13-F?
The "C" suffix denotes bi-directionality: SMBJ10CA-13-F clamps transients equally in both voltage polarities, while SMBJ10A-13-F is uni-directional and requires correct anode/cathode orientation. Both share identical standoff (10V), breakdown (11.1–12.8V), and clamping (17.0V) specifications, but only the "C" version supports AC-coupled or floating-ground applications without polarity concerns.
Can SMBJ10CA-13-F be used on a 12V automotive power rail?
Yes - its 10V standoff voltage provides sufficient margin above nominal 12V system voltage during normal operation, while its 17.0V clamping voltage stays well below the 24V–36V absolute maximum ratings of most automotive-grade power management ICs. It meets ISO 7637-2 Pulse 1 and Pulse 2a requirements when paired with appropriate series impedance.
What is the thermal derating behavior above +25°C ambient?
SMBJ10CA-13-F derates linearly at 4.8W/°C above +25°C ambient temperature. At +75°C ambient, its peak pulse power drops to 360W (600W − 4.8W × 50°C), and its steady-state power dissipation is limited to 5.0W at lead temperature +75°C per Fig. 6 in DS19002 Rev. 20-2.
Does SMBJ10CA-13-F have polarity markings on the package?
No - bi-directional TVS diodes like SMBJ10CA-13-F omit the cathode band marking found on uni-directional variants. The SMB package has two identical terminals; orientation during PCB placement is irrelevant. This simplifies layout and eliminates polarity-related assembly errors.
