Product details
Overview
SMCJ110AQ-13-F from Diodes Incorporated is a unidirectional 1,500W automotive transient voltage suppressor (TVS) diode with 110V reverse standoff voltage (VRWM), 122V minimum breakdown voltage (VBR), and 177V maximum clamping voltage (VC) at 8.4A peak pulse current (IPP). It delivers AEC-Q101 qualification, ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD compliance, and is designed for primary overvoltage protection in 12V/24V/48V automotive power nets.
For engineers reviewing the SMCJ110AQ-13-F datasheet, SMCJ110AQ-13-F pinout, SMCJ110AQ-13-F application, or SMCJ110AQ-13-F equivalent, this part supports critical surge immunity validation in engine control units, body control modules, infotainment power rails, and ADAS sensor interfaces where precise clamping, low leakage (<5µA @ VRWM), and IATF 16949 traceable manufacturing are mandatory.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when transient voltage exceeds its 110V standoff threshold. Its glass-passivated junction ensures stable VBR (122–135V) and fast response (<1.0 ps), enabling suppression of ISO7637-2 Pulse 1 (−100V), Pulse 2a (+50V), Pulse 3a (−150V), and Pulse 3b (+100V) transients without latch-up or thermal runaway.
Designed for surface-mount integration in high-reliability automotive subsystems, it features a robust SMC package rated for −55°C to +150°C junction operation, 200A non-repetitive forward surge capability (8.3ms half-sine), and 5W steady-state power dissipation at TL = +75°C - supporting long-term reliability under cyclic load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 1500W - sustains single-event surges up to 8.4A at 177V clamping without failure |
| Reverse Standoff Voltage | 110V - defines maximum continuous DC operating voltage before conduction begins |
| Clamping Voltage | 177V @ IPP = 8.4A - limits transient voltage seen by downstream ICs during ISO7637-2 Pulse 1/3a events |
| Breakdown Voltage | 122V min / 135V max @ IT = 1mA - ensures tight VBR tolerance for predictable turn-on behavior |
| Leakage Current | <5µA @ VRWM - prevents excessive quiescent drain in always-on vehicle modules |
| Operating Temperature | −55°C to +150°C - validated for under-hood and transmission-control environments |
| AEC-Q101 Qualified | Yes - certified for automotive-grade stress testing including HTGB, HTRB, and TCT |
Pinout & Package
Package: SMC (DO-214AB), molded plastic, UL 94V-0 rated, 0.21g weight, cathode band polarity indicator. Moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |

Key Features
| Feature | Design Value |
|---|---|
| 1,500W peak pulse rating | Enables single-event suppression of severe load-dump and inductive-switching transients without degradation |
| Glass-passivated die construction | Delivers stable VBR and low leakage across temperature and lifetime, critical for ASIL-B/C systems |
| AEC-Q101 qualification & IATF 16949 manufacturing | Guarantees process control, lot traceability, and failure mode coverage required for automotive PPAP submission |
| ISO10605-compliant ESD protection | Withstands ±30kV air/contact discharge - eliminates need for secondary ESD components on CAN/LIN lines |
| Lead-free, halogen-free, RoHS 3 compliant | Meets global environmental regulations and solder-reflow compatibility for automated SMT assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional automotive TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SAC110-13-F | Same VRWM (110V) but lower PPK (600W); uses SMA package (smaller footprint, lower thermal mass) | Limited to lower-energy transients (e.g., ISO7637-2 Pulse 3b only); not qualified for Pulse 1/2a in high-power ECUs | Select only for space-constrained, low-surge sub-systems where 1500W headroom is unnecessary |
| SMCJ110A-Q | Identical electrical specs but non-tape-and-reel packaging (bulk); lacks -13-F reel marking and RoHS 3 documentation traceability | Not PPAP-capable; unsuitable for production release requiring full automotive change control and lot-level compliance records | Use only for prototyping or non-automotive industrial evaluation; avoid for Tier 1 production builds |
Compared with SAC110-13-F and SMCJ110A-Q, SMCJ110AQ-13-F uniquely combines 1500W surge capacity, AEC-Q101 certification, PPAP readiness, and RoHS 3/halogen-free compliance - making it the only option qualified for high-integrity automotive power rail protection where both energy handling and supply-chain governance are mandatory.

FAQ
Is SMCJ110AQ-13-F bidirectional or unidirectional?
SMCJ110AQ-13-F is unidirectional. The absence of the "C" suffix (e.g., SMCJ110CAQ-13-F) confirms its single-polarity configuration. It conducts only during reverse overvoltage events, with cathode connected to the protected line and anode to ground - essential for DC power rail protection where polarity reversal must be blocked.
What is the maximum clamping voltage at 8.4A, and how is it measured?
The maximum clamping voltage is 177V at 8.4A peak pulse current (IPP), measured using the standardized 10×1000µs double-exponential waveform per REA and IEC 61000-4-5. This value is guaranteed across −55°C to +150°C and represents worst-case voltage imposed on downstream circuitry during surge events.
Does this TVS diode require a heatsink in typical automotive applications?
No external heatsink is required. Its 5W steady-state power dissipation rating at TL = +75°C and SMC package thermal resistance (RθJA ≈ 50°C/W) enable safe operation under continuous 110V bias with <5µA leakage. Heatsinking is only needed if subjected to repetitive surges exceeding 4 pulses/minute - a condition outside standard ISO7637-2 test profiles.
How does SMCJ110AQ-13-F differ from industrial-grade SMCJ110A-13-F?
SMCJ110AQ-13-F adds AEC-Q101 qualification, IATF 16949 manufacturing, PPAP documentation support, and enhanced traceability (date-code + lot marking per AIAG standards). Electrically identical, it differs solely in process control rigor, test coverage, and automotive-specific reliability reporting - required for Tier 1 production but unnecessary for non-automotive use.
