Product details
Overview
SMCJ36CAQ-13-F from Diodes Incorporated is a bidirectional 1,500W automotive transient voltage suppressor (TVS) in SMC package, with 36V reverse standoff voltage (VRWM), 58.1V max clamping voltage (VC) at 25.8A 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 SMCJ36CAQ-13-F datasheet, SMCJ36CAQ-13-F pinout, SMCJ36CAQ-13-F application, or SMCJ36CAQ-13-F equivalent, key selection criteria include clamping performance under 10/1000μs surge, bidirectional polarity for AC-coupled lines, AEC-Q101 compliance, SMC thermal derating above +25°C, and compatibility with automated SMT assembly using lead-free reflow profiles.
Technical Context
This TVS diode uses glass-passivated junction construction to achieve fast response time (<1.0 ns) and stable breakdown behavior across -55°C to +150°C operating range. Its bidirectional configuration enables symmetrical clamping on both polarities without external circuitry.
The device operates as a voltage-clamped shunt protector: during transients exceeding VRWM = 36V, it avalanches to limit voltage to ≤58.1V at IPP = 25.8A (10×1000μs waveform), dissipating up to 1,500W peak pulse power while maintaining <5.0μA leakage at rated standoff.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - sustains single 10×1000μs surges per ISO7637-2 without failure |
| Reverse Standoff Voltage | 36V - maximum continuous DC or RMS voltage before clamping initiates |
| Max Clamping Voltage | 58.1V @ 25.8A - limits transient voltage seen by downstream ICs during worst-case surge |
| Breakdown Voltage | 40.0–44.2V @ 1mA - ensures reliable avalanche onset margin above VRWM |
| Leakage Current | ≤5.0μA @ 36V - negligible standby power loss and signal integrity impact |
| Operating Temperature | -55°C to +150°C - supports engine compartment placement per AEC-Q101 requirements |
| Package | SMC - surface-mount outline with 6.6–7.11mm body width, optimized for high-current PCB trace routing |
Pinout & Package
SMC package: molded plastic body (UL 94V-0), cathode band omitted (bidirectional), matte tin-plated terminals, 0.21g mass, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (Bidirectional) | Surge current path | Both terminals function identically - no polarity dependency; connects across protected line and ground |
| Case / Body | Thermal conduction path | Exposed copper pad on bottom surface provides primary heat dissipation to PCB copper pour |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals or floating bus lines without polarity concerns |
| Glass-passivated die | Ensures stable VBR over temperature and lifetime, critical for automotive reliability |
| AEC-Q101 qualification | Validated for automotive use including HTOL, TC, UHAST, and ESD stress testing |
| Lead-free & green | RoHS 3 compliant with <900ppm Br/Cl and <1000ppm Sb - meets Tier 1 auto supplier material declarations |
| 10×1000μs waveform rating | Directly matches ISO7637-2 Pulse 1, 2a, 3a, and 3b test conditions for design validation |
Applications
| Infotainment Power Bus Protection | Body Control Module CAN Transceiver Lines |
|---|---|
Use Scenario: Protecting 12V supply rail feeding head unit MCU, display driver, and audio amplifier from load dump and alternator ripple. IC Role / Device Role / Timing Role: Shunt TVS placed between VBAT and GND, clamping transients before they reach LDOs and PMICs. Use Value: Limits voltage to ≤58.1V during 100V ISO7637-2 Pulse 1 event, preventing latch-up or gate oxide damage in downstream silicon. | Use Scenario: Safeguarding bidirectional CAN_H/CAN_L differential pair against ESD and coupled surges in door module wiring harnesses. IC Role / Device Role / Timing Role: Bidirectional TVS connected across CAN_H–CAN_L and to chassis ground, suppressing common-mode and differential transients. Use Value: Maintains signal integrity by clamping ±30kV ISO10605 contact discharge without forward conduction distortion on data lines. |
| Engine Control Unit Sensor Inputs | ADAS Camera Power Interface |
Use Scenario: Shielding analog sensor inputs (e.g., MAP, O2, coolant temp) from ignition noise and relay switching spikes. IC Role / Device Role / Timing Role: Low-leakage TVS placed at connector entry point, referenced to sensor ground plane. Use Value: Delivers <5.0μA IR at 36V standoff, avoiding DC offset errors in precision ratiometric measurements. | Use Scenario: Protecting 5V/12V camera module power input from hot-swap transients and cable discharge events. IC Role / Device Role / Timing Role: Primary clamping device upstream of DC-DC converter, sized for 1500W peak dissipation. Use Value: Handles 25.8A IPP without thermal runaway, enabling compact layout with minimal heatsinking on small camera PCBs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC36C-TB-E3 | Same VRWM (36V) and bidirectional configuration, but lower PPK = 600W and higher VC = 64.8V @ 9.3A | Limited to lower-energy transients (e.g., IEC61000-4-2 only); unsuitable for ISO7637-2 Pulse 1 (-100V) | Select when cost sensitivity outweighs automotive surge robustness and board space allows parallel devices. |
| 1.5KE36CA | Through-hole DO-201 package, same electrical specs, but no AEC-Q101 qualification and higher thermal resistance | Not approved for production automotive ECUs; restricted to industrial or aftermarket designs | Choose only for prototyping or non-automotive applications where SMT assembly is unavailable. |
Compared with SAC36C-TB-E3 and 1.5KE36CA, SMCJ36CAQ-13-F delivers superior automotive-grade surge immunity (1500W vs. 600W/1500W), validated AEC-Q101 reliability, and SMT-compatible thermal performance-making it the sole qualified option for front-line vehicle power rail protection.

FAQ
What does the 'C' suffix in SMCJ36CAQ-13-F signify?
The 'C' denotes bidirectional configuration: both terminals behave identically under positive and negative transients, eliminating polarity concerns during PCB layout. This differs from unidirectional versions (e.g., SMCJ36AQ-13-F) that require correct anode/cathode orientation relative to ground.
How is SMCJ36CAQ-13-F mounted and soldered?
It uses standard SMC footprint with 2.00–2.50mm terminal spacing and requires reflow per J-STD-020 Level 1 profile. The matte tin finish ensures compatibility with lead-free solder (SnAgCu), and the UL 94V-0 mold compound withstands peak temperatures up to 260°C for 10 seconds.
Does this TVS require a heatsink for 1500W pulse handling?
No external heatsink is needed for single-pulse events: the SMC package's exposed copper pad transfers heat directly to PCB copper pours. Derating applies only for repetitive pulses (>4 per minute), where ambient temperature and board copper area determine safe duty cycle per Figure 1 in DS40741.
Can SMCJ36CAQ-13-F replace older SMCJ36CA parts?
Yes - the -13-F suffix indicates 3000-piece tape-and-reel packaging with RoHS 3 and halogen-free compliance. Electrically and mechanically identical to legacy SMCJ36CA, but with updated environmental certifications required by Tier 1 automotive suppliers since 2022.
