Product details
Overview
SMCJ10AQ-13-F from Diodes Incorporated is a unidirectional 1,500W automotive transient voltage suppressor (TVS) diode with 10V reverse standoff voltage, 17.0V max clamping voltage at 88.2A peak pulse current, and AEC-Q101 qualification for under-hood and powertrain electronics protection against ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD events.
For engineers reviewing the SMCJ10AQ-13-F datasheet, SMCJ10AQ-13-F pinout, SMCJ10AQ-13-F application, or SMCJ10AQ-13-F equivalent, key selection criteria include clamping voltage margin vs. protected IC VDD, peak surge current capability under 10/1000μs waveform, thermal derating above +25°C ambient, and SMC package solderability per MIL-STD-202.
Technical Context
This TVS diode operates as a shunt-clamping overvoltage protection device in parallel with sensitive automotive loads. It exhibits fast response time (<1 ns), low dynamic impedance during clamping, and stable breakdown behavior across -55°C to +150°C junction temperature range.
Its glass-passivated die construction ensures robust surge handling without degradation under repeated 8.3ms half-sine surges up to 200A, while the unidirectional configuration provides forward conduction path only during negative transients-critical for battery line protection where reverse polarity is not expected.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - sustains single 10×1000μs transients without failure |
| Reverse Standoff Voltage | 10.0V - maximum continuous DC or RMS voltage before significant leakage |
| Clamping Voltage @ IPP | 17.0V at 88.2A - limits voltage seen by downstream circuit during worst-case surge |
| Breakdown Voltage | 11.1–12.3V @ 1.0mA - ensures reliable turn-on before clamping threshold exceeded |
| Leakage Current | <5.0μA @ 10V - negligible standby power loss in always-on vehicle modules |
| Operating Temperature | -55°C to +150°C - supports engine bay, transmission control, and ADAS sensor placement |
| AEC-Q101 Qualified | Yes - validated for automotive reliability including HTOL, TC, UHAST, and ESD testing |
Pinout & Package
Package: SMC (DO-214AB), surface-mount molded plastic body with UL 94V-0 rating, cathode band polarity indicator, 0.21g mass, and matte tin lead finish solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side connection point | Connected to ground or low-impedance return path to sink surge current |
| Cathode | High-side connection point | Connected to protected line (e.g., 12V battery rail); cathode band marks this terminal |
Key Features
| Feature | Design Value |
|---|---|
| 1,500W peak pulse rating | Enables protection against severe ISO7637-2 Pulse 1 (-100V) and Pulse 3a (-150V) without thermal runaway |
| Glass-passivated die | Prevents moisture ingress and metallization corrosion in high-humidity under-hood environments |
| AEC-Q101 qualification | Confirms suitability for safety-critical automotive systems requiring PPAP documentation and IATF 16949 traceability |
| Lead-free & halogen-free | Meets RoHS 3 and automotive green material requirements (<900ppm Br/Cl, <1000ppm Sb) |
| Fast response time | <1 ns turn-on ensures clamping initiates before most microcontroller I/O pins experience overstress |
Applications
| Engine Control Unit (ECU) Power Input | Body Control Module (BCM) CAN Bus Lines |
|---|---|
Use Scenario: Protecting 12V supply rail of gasoline/diesel ECU against load dump and alternator ripple. IC Role / Device Role / Timing Role: Shunt TVS placed between battery rail and ground, clamping transients before they reach LDOs and MCU power domains. Use Value: Limits voltage excursion to ≤17.0V during ISO7637-2 Pulse 1 (-100V), preventing brownout resets and gate oxide damage in 3.3V/5V logic. | Use Scenario: Safeguarding isolated CAN transceivers from coupled surges on vehicle wiring harnesses. IC Role / Device Role / Timing Role: Unidirectional TVS connected from CAN_H/CAN_L to chassis ground, suppressing common-mode transients without affecting differential signaling. Use Value: Maintains signal integrity by clamping surges within ±17V window, avoiding transceiver latch-up during ISO7637-2 Pulse 2a (+50V) events. |
| Advanced Driver Assistance Systems (ADAS) Camera Power | Electric Power Steering (EPS) Motor Driver Supply |
Use Scenario: Securing 5V/12V bias rails feeding image sensors and ISP processors in front/rear cameras. IC Role / Device Role / Timing Role: Primary overvoltage clamp on camera module input, coordinated with secondary ceramic capacitors for high-frequency filtering. Use Value: Prevents pixel corruption and sensor reset by limiting clamped voltage to 17.0V during 30kV contact discharge (ISO10605), preserving image capture continuity. | Use Scenario: Shielding H-bridge gate drivers and current sense amplifiers from motor back-EMF spikes and battery reversal transients. IC Role / Device Role / Timing Role: Bidirectional-capable unidirectional TVS (used in dual configuration) across motor phase terminals and supply rails. Use Value: Absorbs 200A peak forward surge (IFSM) without parametric shift, ensuring uninterrupted torque delivery during EPS assist maneuvers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC10-12 | Lower 1200W PPK rating; 18.0V clamping at 66.7A; same SMC package | Marginally lower surge immunity; suitable for non-critical lighting or HVAC modules | Select when cost sensitivity outweighs need for full ISO7637-2 Pulse 1 compliance |
| 1.5SMC10A | Same 1500W rating but no AEC-Q101 qualification; higher IR (10μA @ 10V) | Not approved for automotive production; limited to industrial or aftermarket use | Choose only for prototyping or non-safety-critical test fixtures |
Compared with SAC10-12 and 1.5SMC10A, SMCJ10AQ-13-F delivers superior automotive-grade reliability via AEC-Q101 validation, tighter clamping (17.0V vs. 18.0V), and lower leakage-making it the preferred choice for production ECUs, ADAS, and EPS systems requiring zero field returns.

FAQ
What is the maximum clamping voltage of SMCJ10AQ-13-F under standard test conditions?
The maximum clamping voltage is 17.0V measured at 88.2A peak pulse current using the 10×1000μs waveform defined in REA standards. This value is guaranteed across the full operating temperature range (-55°C to +150°C) and represents the upper limit of voltage imposed on protected circuitry during worst-case surge events.
Is SMCJ10AQ-13-F bidirectional or unidirectional?
SMCJ10AQ-13-F is unidirectional, indicated by the absence of "C" in its part number suffix. It conducts only during reverse-biased overvoltage events-i.e., when cathode voltage exceeds anode voltage-and blocks forward current like a standard rectifier diode, making it ideal for battery rail protection.
Does SMCJ10AQ-13-F require derating at elevated ambient temperatures?
Yes-its peak pulse power must be linearly derated above +25°C ambient per Figure 1 in DS40741 Rev. 8-2. At +75°C, rated PPK drops to approximately 75% (1125W), and at +125°C, it falls to ~40% (600W), necessitating layout-aware thermal design and potential parallel device usage in high-temperature zones.
How does the SMC package of SMCJ10AQ-13-F compare to SMA or SMB in terms of surge handling?
The SMC (DO-214AB) package offers larger die attach area and lower thermal resistance than SMA (DO-214AC) or SMB (DO-214AA), enabling higher IFSM (200A vs. 100A for SMA) and improved heat dissipation during repetitive surge events-critical for automotive applications where multiple load-dump occurrences may occur during vehicle operation.
