Product details
Overview
SMCJ10CAQ-13-F from Diodes Incorporated is a bidirectional 1,500W automotive transient voltage suppressor (TVS) diode in SMC package, with 10V reverse standoff voltage (VRWM), 17.0V max clamping voltage (VC) at 88.2A peak pulse current (IPP), and AEC-Q101 qualification for under-hood power line protection against ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD events.
For engineers reviewing the SMCJ10CAQ-13-F datasheet, SMCJ10CAQ-13-F pinout, SMCJ10CAQ-13-F application, or SMCJ10CAQ-13-F equivalent, this page delivers verified electrical specs, automotive compliance details, clamping performance under standardized surge waveforms, and direct substitution guidance for robust vehicle electronics design.
Technical Context
This bidirectional TVS operates symmetrically across polarity, delivering sub-nanosecond response to transients while maintaining low leakage (<5.0 µA at VRWM) and stable clamping (VC = 17.0V @ IPP = 88.2A per 10/1000µs waveform). Its glass-passivated die ensures consistent breakdown (VBR min/max = 11.10V/12.3V @ IT = 1.0mA) and thermal stability over -55°C to +150°C junction range.
Designed for IATF 16949-certified production, it supports PPAP documentation and meets stringent automotive change control requirements. The SMC package enables high-power dissipation (1500W PPK) with 0.21g mass and UL 94V-0 flammability rating, suitable for automated SMT assembly on engine control units and body electronics PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - sustains single 10/1000µs surges up to 88.2A without failure |
| Reverse Standoff Voltage | 10.0V - maximum continuous DC or RMS voltage before significant leakage |
| Clamping Voltage | 17.0V @ 88.2A - limits downstream circuit voltage during ISO7637-2 Pulse 1 (-100V) |
| Breakdown Voltage | 11.10–12.3V @ 1.0mA - defines precise avalanche initiation threshold for bidirectional conduction |
| Leakage Current | <5.0 µA @ 10V - negligible standby power loss in always-on automotive modules |
| Operating Temperature | -55°C to +150°C - validated for under-hood environments including transmission control units |
| AEC-Q101 Qualified | Yes - passed stress tests for automotive reliability including temperature cycling and HTRB |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic UL 94V-0 housing; cathode band omitted due to bidirectional construction; terminals matte tin-plated for RoHS-compliant soldering per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Bidirectional transient path | Either terminal serves as input/output - no polarity dependency for surge suppression |
| Case (exposed pad) | Thermal conduction path | Directly transfers heat to PCB copper pour; requires minimum 25 mm² thermal pad for PM(AV) = 5.0W |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q101 qualified, PPAP-capable, manufactured in IATF 16949 facilities - fulfills OEM Tier-1 supply chain traceability |

| ESD robustness | 30kV air/contact discharge per ISO10605 (C=150pF, R=330Ω) - protects infotainment and ADAS interface ports |
| Low clamping ratio | VC/VRWM = 1.7 - tighter voltage limiting than generic 1.8–2.2 ratios, reducing margin needed for protected ICs |
| Green construction | Halogen- and antimony-free (<900ppm Br/Cl, <1000ppm Sb); RoHS 3 compliant - meets EU automotive material declarations |
Applications
| Engine Control Unit (ECU) Power Input | Body Control Module (BCM) LIN Bus |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC10C-TB-E3/54 (Vishay) | Same VRWM (10V), lower PPK (1000W), higher VC (18.0V @ 70A), SMC package | Limited to lower-energy transients; not AEC-Q101 qualified - suitable for non-safety industrial use only | Select when cost sensitivity outweighs automotive qualification and clamping tightness |
| 1.5KE10CA (ON Semiconductor) | Higher VRWM tolerance (10% vs. 12%), same PPK (1500W), larger DO-201 package (not SMT-compatible) | Requires through-hole assembly; incompatible with high-density automotive PCB layouts | Choose only if legacy board redesign is impractical and manual assembly is acceptable |
Compared with SAC10C-TB-E3/54 and 1.5KE10CA, SMCJ10CAQ-13-F uniquely combines AEC-Q101 compliance, SMC surface-mount form factor, and lowest clamping ratio (1.7) among 10V bidirectional TVS diodes - critical for protecting modern 3.3V automotive MCUs without derating margins.

FAQ
What does the "C" suffix in SMCJ10CAQ-13-F indicate?
The "C" denotes bidirectional construction, meaning the device provides symmetrical clamping for both positive and negative transients without polarity orientation during placement. This eliminates risk of incorrect installation on differential buses like LIN or CAN FD, and supports ESD protection on unidirectional signal lines where voltage polarity reversal may occur.
How does SMCJ10CAQ-13-F differ from standard SMCJ10A (unidirectional)?
SMCJ10CAQ-13-F has identical VRWM (10V), PPK (1500W), and package but lacks a cathode band and conducts equally in both directions. Unidirectional SMCJ10A clamps only negative transients on the cathode side and requires correct orientation; the "C" version simplifies layout and eliminates polarity-check steps in automated assembly for bidirectional surge paths.
Is thermal derating required for continuous operation?
Yes - steady-state power dissipation is rated at 5.0W only when lead temperature (TL) is maintained at +75°C. At ambient temperatures above +75°C or with insufficient PCB copper area, power must be reduced per Fig. 6 derating curve; for example, at TL = +100°C, PM(AV) drops to ~3.2W to avoid exceeding TJ = +150°C.
Can SMCJ10CAQ-13-F replace SMCJ10AQ-13-F in existing designs?
No - SMCJ10AQ-13-F is unidirectional and will fail catastrophically if subjected to reverse-polarity surges beyond its forward voltage rating. Substitution requires full schematic and layout review: bidirectional use demands removal of polarity-sensitive components (e.g., series diodes), verification of clamping symmetry in test waveforms, and validation of no unintended DC bias paths.
