Product details
Overview
SMCJ8.0AQ-13-F from Diodes Incorporated is a unidirectional 1500W automotive transient voltage suppressor (TVS) diode in SMC package, with 8.0V reverse standoff voltage (VRWM), 8.89–9.83V breakdown voltage (VBR), and 13.6V max clamping voltage (VC) at 110.3A peak pulse current. It protects CAN, LIN, and sensor interfaces in engine control units and body electronics against ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD surges.
For engineers reviewing the SMCJ8.0AQ-13-F datasheet, SMCJ8.0AQ-13-F pinout, SMCJ8.0AQ-13-F application, or SMCJ8.0AQ-13-F equivalent, this page delivers verified AEC-Q101 qualification status, clamping performance under 10/1000μs transients, thermal derating curves, and IATF 16949 manufacturing traceability - all critical for automotive-grade surge protection design validation.
Technical Context
This TVS diode operates as a unidirectional clamping device, leveraging avalanche breakdown to limit transient overvoltages before they damage downstream ICs. Its glass-passivated die ensures stable VBR tolerance (±5%) and low leakage (<50µA at VRWM), while its 1500W peak pulse rating supports high-energy automotive load dump events.
The device complies with ISO7637-2 Pulse 1 (−100V), Pulse 2a (+50V), Pulse 3a (−150V), and Pulse 3b (+100V), and meets ISO10605 ESD requirements (30kV air/contact discharge). Its −55°C to +150°C operating junction temperature range enables placement near high-heat sources like powertrain ECUs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - sustains single 10/1000μs transients up to 110.3A without failure |
| Reverse Standoff Voltage | 8.0V - maximum continuous DC voltage before significant leakage; sets minimum system operating margin |
| Clamping Voltage | 13.6V @ 110.3A - limits transient voltage seen by protected ICs during worst-case surge |
| Breakdown Voltage | 8.89–9.83V @ 1.0mA - tight VBR window ensures predictable turn-on and avoids false triggering |
| Leakage Current | <50µA @ 8.0V - negligible standby power loss and no signal integrity impact on low-power sensors |
| Operating Temperature | −55°C to +150°C - qualified for under-hood automotive environments including transmission control modules |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, molded plastic UL 94V-0 housing; cathode indicated by band; weight ≈0.21g; moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to protected line (e.g., CAN_H); conducts only during negative transients when used unidirectionally |
| Cathode | Current exit point during reverse-biased clamping | Connected to ground; avalanche conduction begins here when line voltage exceeds VRWM |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 Qualified | Validated for automotive use with PPAP capability and IATF 16949 manufacturing control |
| Glass Passivated Die | Ensures stable VBR over temperature and lifetime; eliminates passivation-related leakage drift |
| Fast Response Time | <1ps - clamps transients before sensitive logic or analog circuitry responds |
| Lead-Free & Halogen-Free | RoHS 3 compliant (2015/863/EU); <900ppm Br/Cl, <1000ppm Sb - meets global automotive environmental mandates |
Applications
| Engine Control Unit (ECU) | Body Control Module (BCM) |
|---|---|
Use Scenario: Protects 5V sensor supply rails and CAN FD transceivers from load dump and alternator ripple-induced spikes. IC Role / Device Role: Unidirectional TVS placed between power rail and chassis ground to clamp negative-going transients. Use Value: Limits voltage to ≤13.6V during ISO7637-2 Pulse 1 (−100V), preventing latch-up in microcontrollers and ADCs. | Use Scenario: Shields LIN bus lines in door modules from ESD events during assembly and field operation. IC Role / Device Role: Clamping diode on LIN data line referenced to local ground, absorbing contact discharge per ISO10605. Use Value: Withstands 30kV contact discharge without degradation, maintaining LIN communication integrity after repeated ESD strikes. |
| Advanced Driver Assistance Systems (ADAS) | Electric Power Steering (EPS) |
Use Scenario: Safeguards camera module power inputs against battery disconnection transients in front-end ADAS domain controllers. IC Role / Device Role: Primary surge suppression on 12V input rail upstream of DC/DC converters. Use Value: 1500W rating handles ISO7637-2 Pulse 3b (+100V) without thermal runaway, preserving image sensor functionality. | Use Scenario: Guards motor driver gate drive signals from inductive kickback during EPS motor commutation. IC Role / Device Role: Low-capacitance TVS on isolated gate drive lines to suppress sub-10ns ringing. Use Value: Sub-1ps response prevents false MOSFET turn-on caused by fast dv/dt transients, avoiding shoot-through faults. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional automotive TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC8.0 | Same VRWM (8.0V) but lower PPK (600W); higher VC (14.0V @ 43A) | Limited to lower-energy transients (e.g., ISO7637-2 Pulse 3b only); not suitable for load dump | Select only for cost-sensitive non-critical subsystems where 1500W headroom is unnecessary |
| SMCJ8.0A | Same electrical specs but lacks AEC-Q101 qualification and IATF 16949 traceability | Not approved for production automotive programs requiring PPAP documentation | Acceptable for prototyping or industrial applications; reject for OEM Tier 1 production |
Compared with SAC8.0 and SMCJ8.0A, SMCJ8.0AQ-13-F uniquely combines full AEC-Q101 compliance, 1500W surge capacity, and documented IATF 16949 manufacturing - making it the only choice for safety-critical automotive ECUs requiring audit-ready component traceability.

FAQ
Is SMCJ8.0AQ-13-F bidirectional or unidirectional?
SMCJ8.0AQ-13-F is unidirectional. The absence of "C" in the part number (e.g., vs. SMCJ8.0CAQ-13-F) confirms it has polarity - anode and cathode terminals - and clamps only reverse-voltage transients. It must be installed with cathode toward ground to protect positive-rail circuits.
What is the maximum clamping voltage at rated peak current?
The maximum clamping voltage is 13.6V at 110.3A peak pulse current (IPP), measured using the standard 10/1000μs waveform per REA. This value is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuitry during surge events.
Does this TVS diode require a heatsink in typical automotive applications?
No heatsink is required. With a steady-state power dissipation of 5.0W at TL = +75°C and thermal resistance (RθJL) enabling operation up to +150°C junction temperature, the SMCJ8.0AQ-13-F relies on PCB copper area for thermal management - consistent with standard SMC footprint layout guidelines.
How does SMCJ8.0AQ-13-F differ from industrial-grade SMCJ8.0A?
SMCJ8.0AQ-13-F adds AEC-Q101 qualification, PPAP documentation support, and manufacturing in IATF 16949-certified facilities. Electrically identical, it undergoes extended stress testing (HTOL, TC, UHAST) and receives lot-level traceability - mandatory for automotive production but not for industrial use.
