Product details
Overview
SMCJ5.0CAQ-13-F from Diodes Incorporated is a bidirectional 1,500W automotive transient voltage suppressor (TVS) diode in SMC package, with 5.0V reverse standoff voltage, 9.2V max clamping voltage at 163A peak pulse current, and AEC-Q101 qualification for ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD protection in vehicle power-line interfaces.
For engineers reviewing the SMCJ5.0CAQ-13-F datasheet, SMCJ5.0CAQ-13-F pinout, SMCJ5.0CAQ-13-F application, or SMCJ5.0CAQ-13-F equivalent, this part supports high-reliability automotive surge suppression where fast response (<1 ns), low clamping ratio (1.84× VRWM), and IATF 16949-manufactured traceability are required.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering 1,500W peak pulse power per the 10/1000μs waveform. Its glass-passivated junction ensures stable breakdown at 6.40–7.07V (VBR @ 10mA) and limits leakage to ≤1000μA at 5.0V VRWM.
Designed for automotive-grade robustness, it sustains operation from –55°C to +150°C junction temperature, meets ISO10605 ±30kV air/contact discharge, and clamps transients within 1 ns-critical for protecting CAN, LIN, and sensor supply rails against load dump and inductive switching events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - withstands ISO7637-2 Pulse 1 (–100V) without failure |
| Reverse Standoff Voltage | 5.0V - defines maximum continuous operating voltage before clamping initiates |
| Clamping Voltage | 9.2V @ 163A - limits downstream IC voltage stress during 10/1000μs surge |
| Breakdown Voltage | 6.40–7.07V @ 10mA - ensures precise, repeatable turn-on threshold |
| Leakage Current | ≤1000μA @ 5.0V - avoids excessive quiescent drain in always-on vehicle modules |
| Response Time | <1 ns - reacts faster than most microcontroller I/O protection circuits |
| Operating Temp Range | –55°C to +150°C - supports under-hood placement near engine control units |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic body with UL 94V-0 rating, cathode band omitted (bidirectional device), 0.21g weight, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity) | Conducts during negative surges; symmetrical with Cathode for bidirectional clamping |
| Cathode | Transient current entry (positive polarity) | Conducts during positive surges; no polarity marking due to bidirectional construction |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC-coupled or floating automotive signals (e.g., LIN bus, analog sensor outputs) |
| Glass-passivated die | Ensures long-term stability of VBR and leakage under thermal cycling and humidity exposure |
| AEC-Q101 qualification | Validates reliability for automotive powertrain and chassis applications requiring PPAP documentation |
| Lead-free, halogen-free | Meets RoHS 3 and automotive green material requirements without compromising surge performance |
Applications
| Engine Control Unit (ECU) Power Input | Body Control Module (BCM) LIN Bus |
|---|---|

IC Role / Device Role / Timing Role: Primary overvoltage clamp placed upstream of DC-DC converter input. Use Value: Limits input voltage to ≤9.2V during 163A surge, preventing MOSFET gate oxide damage and regulator latch-up. | Use Scenario: Shields LIN transceiver PHY layer from ESD events (ISO10605 ±30kV) and battery disconnect spikes. IC Role / Device Role / Timing Role: Bidirectional shunt protector on LIN signal line (VPIN/VNIN) referenced to local ground.

| Automotive Camera Power Supply | ADAS Radar Sensor Bias Rail |
Use Scenario: Guards 12V power input of rear-view camera module against jump-start surges and grounding faults. IC Role / Device Role / Timing Role: First-line defense before LDO regulator; placed adjacent to connector. Use Value: Absorbs 1500W pulses without degradation, maintaining <5μA leakage to avoid dark-current interference in CMOS image sensors. | Use Scenario: Protects 5V bias rail of 77GHz radar MMICs from ignition noise coupling via shared vehicle harnesses. IC Role / Device Role / Timing Role: Low-capacitance (≈1500pF) shunt clamp on RF-sensitive analog supply path. Use Value: Delivers sub-1ns response to preserve phase coherence of radar chirp signals during transient events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional automotive TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC5.0B-TB-E | Same 5.0V VRWM, but lower 600W PPK and 100A IPP; SOD-123FL package | Limited to low-energy infotainment USB ports; insufficient for power-line ISO7637-2 compliance | Select only for space-constrained non-power-line nodes where 1500W margin is unnecessary |
| TPSMA6.0A-Q | Unidirectional, 6.0V VRWM, 1500W PPK, SMA package; lacks bidirectional symmetry | Requires dual-device configuration for AC protection; adds BOM cost and layout area | Choose only when polarity is fixed and board real estate allows two devices |
Compared with SAC5.0B-TB-E and TPSMA6.0A-Q, SMCJ5.0CAQ-13-F uniquely delivers certified bidirectional 1500W surge handling in a single SMC footprint-enabling compact, PPAP-ready protection for critical automotive power and data lines without design compromises.

FAQ
Is SMCJ5.0CAQ-13-F unidirectional or bidirectional?
SMCJ5.0CAQ-13-F is bidirectional, indicated by the "C" suffix in the part number. It provides symmetrical clamping for both positive and negative transients without polarity dependence, making it suitable for AC-coupled or floating signal lines like LIN and sensor bridges.
What is the maximum clamping voltage at rated peak pulse current?
The maximum clamping voltage VC is 9.2V at IPP = 163A, measured using the standardized 10/1000μs double-exponential waveform. This value ensures downstream 5V logic and analog circuits remain within safe operating limits during worst-case surge events.
Does this TVS require a heatsink for 5W steady-state dissipation?
No heatsink is required: the 5.0W PM(AV) rating applies at TL = +75°C lead temperature. In typical automotive PCB layouts with 1 oz copper and standard SMC pad geometry, natural convection suffices-verified by Diodes' Fig. 6 derating curve showing full power capability up to +75°C ambient.
How does SMCJ5.0CAQ-13-F differ from commercial-grade SMCJ5.0CA?
The "AQ" suffix denotes automotive qualification: AEC-Q101 stress testing, PPAP documentation support, IATF 16949 manufacturing, and extended temperature range (–55°C to +150°C). Commercial SMCJ5.0CA lacks these certifications and is rated only to +125°C TJ.
