Product details
Overview
SMBJ60AQ-13-F from Diodes Incorporated is a unidirectional 600W surface-mount automotive transient voltage suppressor (TVS) diode with 60V reverse standoff voltage, 96.8V max clamping voltage at 6.2A peak pulse current, and AEC-Q101 qualification. It protects CAN, LIN, and power-line circuits in engine control units and body electronics against ISO7637-2 Pulse 1 (−150V), Pulse 2a (+112V), and ISO10605 ESD (±30kV).
For engineers reviewing the SMBJ60AQ-13-F datasheet, SMBJ60AQ-13-F pinout, SMBJ60AQ-13-F application, or SMBJ60AQ-13-F equivalent, this page delivers verified electrical specs, automotive compliance evidence, SMB package mechanical data, clamping performance under 10/1000μs surge, and direct alternatives for board-level surge protection design.
Technical Context
This unidirectional TVS operates as a fast-acting shunt clamp triggered by overvoltage events exceeding its 60V VRWM. Its 66.7–73.7V breakdown range (at 1mA IT) ensures reliable turn-on before downstream IC damage, while 96.8V clamping at 6.2A limits energy delivered to protected circuitry during ISO7637-2 transients.
Designed for automotive environments, it sustains −55°C to +175°C junction temperature, supports 100A non-repetitive forward surge (8.3ms half-sine), and delivers 5W steady-state dissipation at TL = +75°C - enabling placement near high-heat sources like power MOSFETs or motor drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - handles ISO7637-2 Pulse 1 (−150V/50Ω) without failure |
| Reverse Standoff Voltage (VRWM) | 60V - blocks normal 12V/24V automotive bus ripple while remaining inactive |
| Max Clamping Voltage (VC) | 96.8V @ IPP = 6.2A - limits voltage seen by protected MCU I/O or transceiver pins |
| Breakdown Voltage (VBR) | 66.7–73.7V @ IT = 1mA - ensures precise, repeatable conduction onset across temperature |
| Leakage Current (IR) | <0.5µA @ VRWM - negligible standby power draw in always-on vehicle modules |
| Operating Temperature | −55°C to +175°C - qualified for under-hood ECU and transmission control applications |
| AEC-Q101 Qualified | Yes - validated for automotive use with PPAP capability and IATF 16949 manufacturing |

|---|---|
Use Scenario: 12V battery feed to microcontroller power supply in gasoline/diesel engine ECUs exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS clamps negative-going transients (ISO7637-2 Pulse 1) and positive surges (Pulse 2a) before they reach LDOs or DC-DC converters. Use Value: Prevents brownout resets and gate oxide damage in PMICs by limiting input voltage to ≤96.8V during 100V+ transients. | Use Scenario: CAN FD physical layer interface (e.g., TJA1057) connected to vehicle wiring harness subject to ESD and coupled noise. IC Role / Device Role / Timing Role: Fast-response shunt device placed between CAN_H/CAN_L and ground to divert ESD strikes (±30kV air/contact) and burst noise. Use Value: Maintains signal integrity by clamping differential transients within ±1V of common-mode baseline, avoiding CAN bus lockup. |
| Body Control Module (BCM) LIN Bus | Automotive Lighting Driver Input |
Use Scenario: LIN slave node (e.g., door module actuator) powered via 12V supply line sharing harness with high-current loads. IC Role / Device Role / Timing Role: Standoff-rated TVS absorbs repetitive switching spikes from adjacent solenoids or relays per ISO7637-2 Pulse 3a/3b. Use Value: Enables robust operation at 19.2kbps without communication errors caused by >200V negative pulses on the LIN bus. | Use Scenario: LED headlamp driver IC input subjected to load dump during battery disconnect/reconnect events. IC Role / Device Role / Timing Role: Primary overvoltage clamp on 24V input rail, coordinated with upstream fuse and downstream ceramic capacitors. Use Value: Limits peak stress on buck controller FETs and gate drivers to <100V, extending lifetime beyond 5,000 thermal cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional automotive TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60A-Q | Same electrical specs; differs only in tape-and-reel packaging (no -13-F suffix) and date-code marking format | No functional difference; suitable for same PCB layouts and automotive qualification requirements | Select when standard Diodes tape-and-reel logistics are preferred over AEC-specific labeling |
| SMCJ60A-Q | Higher 1500W peak power, larger SMC package (7.11 × 6.22 mm vs. SMB's 3.94 × 5.59 mm), identical VRWM/VC | Better suited for high-energy load dump in alternator circuits; requires PCB footprint redesign | Choose for systems needing >100A surge margin where space permits larger package |
Compared with SMBJ60AQ-13-F, SMBJ60A-Q offers identical protection in alternate packaging, while SMCJ60A-Q trades compactness for higher surge capacity - making the SMBJ variant optimal for space-constrained ECU and sensor modules requiring AEC-Q101 traceability.

FAQ
What is the clamping voltage of SMBJ60AQ-13-F at its rated peak pulse current?
The SMBJ60AQ-13-F has a maximum clamping voltage (VC) of 96.8V at 6.2A peak pulse current (IPP), measured using the standardized 10×1000μs waveform per REA definition. This value is guaranteed across the full operating temperature range and ensures protected circuitry remains within safe voltage limits during surge events.
Is SMBJ60AQ-13-F suitable for bidirectional signal lines like CAN or LIN?
No - SMBJ60AQ-13-F is unidirectional and intended for DC-biased lines such as power inputs or single-ended signals. For bidirectional buses like CAN or LIN, the bi-directional variant SMBJ60CAQ-13-F (with "C" suffix) must be used to clamp both positive and negative transients symmetrically.
Does SMBJ60AQ-13-F require derating at elevated ambient temperatures?
Yes - its peak pulse power derates linearly above +25°C at 4.8W/°C, and steady-state power dissipation is limited to 5.0W at lead temperature TL = +75°C. Designers must apply thermal vias and copper pour to maintain junction temperature ≤+175°C under worst-case surge repetition.
How does SMBJ60AQ-13-F differ from commercial-grade SMBJ60A?
SMBJ60AQ-13-F adds AEC-Q101 qualification, PPAP capability, IATF 16949 manufacturing, and automotive-specific change control - distinguishing it from commercial SMBJ60A. The "Q" suffix confirms automotive process controls, lot traceability, and extended reliability testing required for Tier 1 automotive supply chains.
