Product details
Overview
SMCJ13CAQ-13-F from Diodes Incorporated is a bidirectional 1,500W automotive transient voltage suppressor (TVS) diode in SMC package, with 13V reverse standoff voltage (VRWM), 21.5V max clamping voltage (VC) at 69.7A peak pulse current (IPP), 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 SMCJ13CAQ-13-F datasheet, SMCJ13CAQ-13-F pinout, SMCJ13CAQ-13-F application, or SMCJ13CAQ-13-F equivalent, this device serves as a robust, RoHS-compliant, lead-free TVS for automotive 12V system surge suppression where fast response time (<1 ns), low clamping ratio (VC/VRWM = 1.65), and IATF 16949-manufactured reliability are critical selection criteria.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling protection of AC-coupled or floating signal lines without polarity constraints. Its glass-passivated junction ensures stable breakdown behavior under repeated transients, while the 10×1000μs waveform-rated clamping performance aligns with ISO7637-2 Pulse 3b (±100V) and Pulse 1 (−100V) test profiles.
The device exhibits 5.0W steady-state power dissipation at TL = +75°C and derates linearly above ambient, supporting operation from −55°C to +150°C junction temperature. Its 1.0mA test current (IT) and ≤5.0μA reverse leakage at VRWM confirm tight parametric control suitable for low-power automotive sensor and CAN bus interface protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - sustains single 10×1000μs surges up to ISO7637-2 Pulse 1 level without failure |
| Reverse Standoff Voltage | 13.0V - defines maximum continuous operating voltage before clamping initiates |
| Max Clamping Voltage | 21.5V at 69.7A - limits downstream circuit voltage during worst-case transient |
| Breakdown Voltage | 14.4–15.9V @ 1.0mA - ensures reliable turn-on margin above VRWM |
| Operating Temperature | −55°C to +150°C - supports under-hood and powertrain module deployment |
| ESD Rating | ±30kV contact/air per ISO10605 - protects against human-body-model discharges |
| AEC-Q101 Qualified | Yes - validated for automotive use with PPAP capability and IATF 16949 manufacturing |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic body with UL 94V-0 flammability rating, cathode band omitted due to bidirectional construction, weight ≈0.21g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient conduction path | Both terminals function identically; no polarity dependency enables placement on differential or floating nodes |
| Case / Body | Thermal and mechanical interface | Exposed copper pad provides primary thermal path to PCB; requires ≥25 mm² 2-oz copper pour for PM(AV) derating compliance |
Key Features
| Feature | Design Value |
|---|---|
| 1,500W peak pulse power | Enables protection against high-energy load dump events without sacrificial fuse coordination |
| Glass-passivated die | Ensures long-term parameter stability and reduced leakage drift over temperature and lifetime |
| Bidirectional symmetry | Eliminates orientation errors during automated placement and supports AC signal line protection |
| Lead-free, halogen-free, RoHS 3 compliant | Meets automotive environmental mandates including EU 2015/863/EU and OEM green material requirements |
| Fast response time (<1 ns) | Clamps transients before sensitive downstream ICs (e.g., LIN transceivers, MCU I/O) experience overstress |
Applications
| Body Control Module (BCM) Power Input | Automotive Infotainment Display Interface |
|---|---|
Use Scenario: 12V battery feed to BCM subjected to ISO7637-2 Pulse 1 (−100V) and Pulse 3a (−150V) during alternator load dump and switch-off events. IC Role / Device Role / Timing Role: Primary clamping element placed upstream of DC-DC converter input to limit voltage excursion below 24V absolute maximum rating. Use Value: Prevents latch-up or permanent damage to buck controller ICs by holding rail voltage ≤21.5V during 69.7A transient peaks. |
Use Scenario: LVDS or FPD-Link video data lines connecting head unit to TFT display exposed to ESD per ISO10605 (±30kV air/contact). IC Role / Device Role / Timing Role: Bidirectional TVS placed differential pair termination point to shunt ESD energy before reaching serializer/deserializer IC inputs. Use Value: Maintains signal integrity by limiting common-mode voltage excursion to <21.5V without adding capacitance (>100pF) that would degrade 1Gbps+ video bandwidth. |
| Engine Control Unit (ECU) Sensor Supply Line | Automotive CAN FD Transceiver Protection |
Use Scenario: 5V regulated supply to pressure/temperature sensors in engine bay, subject to coupled noise from ignition coils and fuel injectors. IC Role / Device Role / Timing Role: Secondary protection stage after bulk capacitor, clamping fast-rising spikes (tR < 1ns) induced by inductive switching. Use Value: Reduces sensor output error and false fault reporting by limiting supply rail overshoot to ≤21.5V during repetitive 200A surge events. |
Use Scenario: CAN_H/CAN_L lines connected to external connectors vulnerable to ESD and ISO7637-2 Pulse 2a (+50V) during service operations. IC Role / Device Role / Timing Role: Low-capacitance bidirectional TVS placed directly at connector entry to protect transceiver I/O pins without degrading 5Mbps CAN FD edge rate. Use Value: Ensures bus communication continuity by clamping transients within 1ns while maintaining differential impedance match via symmetrical layout. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional automotive TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC13-13-F (Diodes Inc.) | Lower peak power (600W), same VRWM (13V), higher VC (24.4V), smaller SMA package | Limited to lower-energy transients (e.g., ISO10605 only); unsuitable for ISO7637-2 Pulse 1/3a | Select when board space is constrained and surge energy is limited to ≤600W |
| TPSMD13C (Texas Instruments) | Same 1500W rating and 13V VRWM, but 22.0V VC at 68.2A; AEC-Q101 qualified; slightly tighter VBR tolerance | Compatible drop-in replacement with marginally improved clamping; identical thermal footprint | Prefer when TI-sourced BOM consolidation or tighter VBR spec (14.4–15.4V) is required |
Compared with SAC13-13-F and TPSMD13C, SMCJ13CAQ-13-F offers superior clamping ratio (1.65 vs. 1.88 and 1.69), proven IATF 16949 traceability, and broader ISO7637-2 coverage-making it optimal for high-reliability power-line protection where clamping voltage margin and qualification rigor are decisive.

FAQ
Is SMCJ13CAQ-13-F unidirectional or bidirectional?
SMCJ13CAQ-13-F is bidirectional, indicated by the "C" suffix in the part number per Diodes' ordering nomenclature. It provides symmetrical clamping for both positive and negative transients, with no cathode band marking and identical electrical characteristics in either polarity.
What is the maximum clamping voltage at rated peak pulse current?
The maximum clamping voltage (VC) is 21.5V at 69.7A peak pulse current (IPP), measured using the standard 10×1000μs waveform per REA and defined in the Electrical Characteristics table of DS40741 Rev. 8-2.
Does this TVS require a heatsink for 5W steady-state dissipation?
No external heatsink is required; the 5.0W steady-state power dissipation (PM(AV)) is rated at TL = +75°C with proper PCB copper land (≥25 mm² of 2-oz copper). Derating begins linearly above +75°C ambient per Figure 6 in the datasheet.
How does SMCJ13CAQ-13-F differ from commercial-grade SMCJ13A?
SMCJ13CAQ-13-F adds AEC-Q101 qualification, PPAP capability, IATF 16949 manufacturing, enhanced traceability, and stricter lot-level testing versus commercial SMCJ13A. It also features halogen/antimony-free "Green" construction and automotive-specific change control.
