Product details
Overview
SMBJ110AQ-13-F from Diodes Incorporated is a unidirectional 600W surface-mount automotive transient voltage suppressor (TVS) diode with 110V reverse standoff voltage, 177V clamping voltage at 3.4A peak pulse current, and AEC-Q101 qualification for under-hood electronics protection against ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD surges.
For engineers reviewing the SMBJ110AQ-13-F datasheet, SMBJ110AQ-13-F pinout, SMBJ110AQ-13-F application, or SMBJ110AQ-13-F equivalent, this device is selected for high-reliability 12V/24V automotive power rail surge suppression where precise clamping, low leakage (<0.5µA), and IATF 16949-manufactured consistency are required.
Technical Context
This unidirectional TVS operates as a fast-acting shunt clamp during transients, triggering at 122V breakdown (min) and limiting voltage to ≤177V at 3.4A (10×1000µs waveform). Its 600W peak pulse power rating supports single-event surge immunity without thermal runaway when mounted on PCBs with adequate copper area.
Designed for automotive environments, it maintains stable performance across −55°C to +175°C junction temperature, complies with RoHS 3 and halogen-free "Green" standards, and features matte tin lead finish for reliable solderability per MIL-STD-202.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600W - sustains single 10×1000µs surge events without failure |
| Reverse Standoff Voltage | 110V - blocks normal 24V system operation while remaining inactive |
| Clamping Voltage | 177V @ 3.4A - limits downstream circuit voltage during ISO7637-2 Pulse 1 (−150V) |
| Breakdown Voltage | 122–135V - ensures reliable turn-on before damage threshold of protected ICs |
| Leakage Current | <0.5µA @ 110V - prevents battery drain in always-on vehicle modules |
| Operating Temperature | −55°C to +175°C - supports engine bay placement without derating |
| AEC-Q101 Qualified | Yes - validated for automotive use with PPAP capability and IATF 16949 manufacturing |
Pinout & Package
Package: SMB (DO-214AA), molded plastic body with UL 94V-0 flammability rating, 0.1g weight, and moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (marked band) | Surge current sink | Connected to protected line; conducts transient energy to ground during overvoltage |
| Anode | Reference node | Tied to system ground or low-impedance return path to complete clamping loop |
Key Features
| Feature | Design Value |
|---|---|
| Automotive-grade surge immunity | Validated against ISO7637-2 Pulse 1 (−150V), Pulse 2a (+112V), Pulse 3a (−220V), Pulse 3b (+150V) |
| ESD robustness | 30kV air/contact discharge per ISO10605 (C = 150pF, R = 330Ω) |
| Low clamping ratio | VC/VRWM = 1.61 - tight voltage control minimizes stress on downstream regulators and MCUs |
| Lead-free & green compliance | RoHS 3, halogen-free (<900ppm Br/Cl, <1000ppm Sb), matte tin plating |
Applications
| Engine Control Unit (ECU) Power Input | Body Control Module (BCM) CAN Bus Lines |

FAQ
What is the difference between SMBJ110AQ-13-F and SMBJ110CAQ-13-F?
SMBJ110AQ-13-F is unidirectional (cathode-banded), designed for DC power rail protection where polarity is fixed; SMBJ110CAQ-13-F is bidirectional, used on AC-coupled or differential lines like CAN or LIN buses. Their clamping behavior differs: unidirectional clamps only above VRWM, while bidirectional clamps symmetrically around 0V.
Does SMBJ110AQ-13-F require heatsinking for 600W pulse handling?
No external heatsink is required for single-pulse events, as the 600W rating assumes short-duration (10×1000µs) transients. Thermal design relies on PCB copper area: ≥1 cm² of 2-oz copper per terminal is recommended to sustain repeated surges without exceeding 175°C junction temperature.
Can SMBJ110AQ-13-F be used in 48V mild-hybrid systems?
No - its 110V VRWM and 177V clamping voltage are optimized for 12V/24V architectures. For 48V systems, Diodes recommends SMBJ150AQ-13-F (150V VRWM) or SMBJ170AQ-13-F (170V VRWM) to maintain sufficient margin above nominal bus voltage and load dump peaks.
Is the marking code 'EE' on SMBJ110AQ-13-F traceable to date code?
Yes - per Diodes' marking convention, 'EE' is the product type code for SMBJ110AQ; the adjacent laser-marked 'YWW' (e.g., '524') indicates year-week date code (e.g., 2025, week 24), enabling full lot traceability back to IATF 16949 production records and AEC-Q101 retest reports.
