Product details
Overview
SMCJ17AQ-13-F from Diodes Incorporated is a unidirectional 1,500W automotive-grade transient voltage suppressor (TVS) diode in SMC package, with 17V reverse standoff voltage (VRWM), 27.6V max clamping voltage (VC) at 53.3A 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 SMCJ17AQ-13-F datasheet, SMCJ17AQ-13-F pinout, SMCJ17AQ-13-F application, or SMCJ17AQ-13-F equivalent, this part supports high-reliability automotive surge suppression where precise clamping, fast response (<1 ns), and IATF 16949-manufactured consistency are required - especially in 12V/24V battery rail, LIN/CAN node input, and body control module power inputs.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds 17V VRWM and fully clamping within nanoseconds to limit transients to ≤27.6V at 53.3A (10/1000μs waveform). It sustains 200A non-repetitive forward surge (8.3ms half-sine) and maintains <5μA leakage at VRWM.
Designed for automotive environments, it features glass-passivated die construction, -55°C to +150°C operating junction temperature, and RoHS-compliant matte tin plating. Its SMC package delivers 1.5kW peak power dissipation with UL 94V-0 flammability rating and J-STD-020 Level 1 moisture sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - handles severe ISO7637-2 Pulse 1 (-100V) and Pulse 3a (-150V) without failure |
| Reverse Standoff Voltage (VRWM) | 17.0V - sets minimum operating voltage threshold before clamping activation on 12V automotive systems |
| Max Clamping Voltage (VC) | 27.6V @ IPP = 53.3A - ensures downstream 30V-rated ICs (e.g., CAN transceivers, MCU power rails) remain within safe voltage margin |
| Breakdown Voltage (VBR) | 18.9–20.9V @ IT = 1.0mA - defines tight avalanche onset window for predictable turn-on behavior |
| Peak Pulse Current (IPP) | 53.3A (10/1000μs) - quantifies maximum transient energy absorption capability per event |
| Leakage Current (IR) | ≤5.0μA @ VRWM - minimizes standby power loss and avoids false triggering in low-current sensor circuits |
| Operating Temperature | -55°C to +150°C - supports placement near engines, alternators, or under-dash ECUs without derating |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic with UL 94V-0 rating; cathode band indicates polarity; weight ≈0.21g.
| Pin/Terminal | Circuit Role | Design Meaning |

| Glass-passivated die construction | Enhances long-term reliability under thermal cycling and humidity exposure in engine bay environments |
| Fast response time (<1 ns) | Clamps before sensitive electronics (e.g., microcontrollers, transceivers) experience overvoltage stress |
| Lead-free, halogen-free, RoHS 3 compliant | Meets global automotive environmental mandates (Br+Cl <1500ppm, Sb <1000ppm) without compromising surge performance |
| 1,500W peak pulse rating | Supports repeated surge events per ISO7637-2 test profiles without parameter drift or degradation |
Applications
| Engine Control Unit (ECU) Power Input | CAN Transceiver Protection |
|---|---|
|
Use Scenario: Protecting 12V supply rail of gasoline/diesel engine control units exposed to load dump and alternator ripple. IC Role / Device Role: Primary bidirectional clamping device on main VBAT input, placed upstream of DC-DC converters and LDOs. Use Value: Limits transients to ≤27.6V, preventing latch-up or permanent damage to 3.3V/5V domain MCUs and analog front-ends. |
Use Scenario: Safeguarding high-speed CAN FD physical layer transceivers (e.g., TJA1057) against ESD and coupled surges. IC Role / Device Role: Secondary protection stage after common-mode choke, shunting differential-mode transients between CANH/CANL lines. Use Value: Maintains signal integrity by clamping without adding >10pF capacitance - verified at 1MHz with <10pF typical total capacitance. |
| Body Control Module (BCM) LIN Bus | Automotive Lighting Driver Input |
|
Use Scenario: Securing LIN bus master node power and data lines in door modules and seat controllers subjected to cable harness coupling. IC Role / Device Role: Unidirectional TVS on VCC rail and bidirectional variant on LIN signal line (if used). Use Value: Enables robust operation across -40°C to +105°C ambient while meeting ISO10605 ±30kV air/contact discharge requirements. |
Use Scenario: Protecting constant-current LED driver ICs (e.g., AL8863) powering headlamps and DRLs from battery reversal and jump-start spikes. IC Role / Device Role: Front-end clamp on input capacitor bank, absorbing 100A-level surges from faulty jump-start connections. Use Value: Withstands 200A 8.3ms half-sine surge (IFSM), preventing catastrophic failure during service interventions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC17-13-F | Same VRWM (17V) and VC (27.6V), but lower PPK = 600W; SOD-123FL package (smaller footprint, lower thermal mass) | Limited to lower-energy transients (e.g., infotainment USB ports); unsuitable for battery rail or load dump | Select only for space-constrained, low-power nodes where 1.5kW clamping is unnecessary |
| SMCJ17A-Q | Identical electrical specs, but non-tape-and-reel (bulk) packaging; same AEC-Q101 qualification and SMC package | No functional difference; used for prototyping or low-volume builds where reel logistics are impractical | Choose for NPI evaluation or small-batch validation; SMCJ17AQ-13-F preferred for automated SMT production |
Compared with SAC17-13-F and SMCJ17A-Q, the SMCJ17AQ-13-F uniquely combines 1.5kW surge capacity, AEC-Q101 compliance, and tape-and-reel readiness - making it the only option qualified for high-volume automotive power rail protection with full production traceability.

FAQ
Is SMCJ17AQ-13-F unidirectional or bidirectional?
SMCJ17AQ-13-F is unidirectional, indicated by the absence of "C" in the part number (e.g., SMCJ17CAQ would be bidirectional). It clamps only during reverse voltage excursions and conducts forward current like a standard diode - ideal for DC power rail protection where polarity is fixed.
What is the maximum steady-state power dissipation for this TVS diode?
The SMCJ17AQ-13-F has a steady-state power dissipation (PM(AV)) of 5.0W at TL = +75°C. This rating applies only to continuous DC or low-frequency conditions - not transient events - and must be derated linearly above +75°C per the Fig. 6 derating curve in DS40741 Rev. 8-2.
Does this part meet AEC-Q101 requirements for automotive use?
Yes - SMCJ17AQ-13-F is explicitly AEC-Q101 qualified, PPAP capable, and manufactured in IATF 16949-certified facilities. Its qualification covers temperature cycling, HTRB, AC/DC life testing, and ESD per AEC-Q101-001, confirming suitability for under-hood and chassis-mounted automotive applications.
How does its clamping voltage compare to similar 17V TVS diodes?
At IPP = 53.3A (10/1000μs), SMCJ17AQ-13-F clamps to ≤27.6V - tighter than industry-standard alternatives like SMAJ17A (VC = 29.2V) due to optimized die geometry and low-inductance SMC package. This 1.6V margin directly improves system-level surge immunity for 30V-rated components.
