Product details
Overview
SMAJ160CAQ-13-F from Diodes Incorporated is a bi-directional automotive-grade transient voltage suppressor (TVS) diode in SMA package, rated for 400W peak pulse power, 160V reverse standoff voltage (VRWM), and 259V maximum clamping voltage (VC) at 1.5A peak pulse current - designed to protect CAN, LIN, and sensor interfaces in engine control units and body electronics against ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD events.
For engineers reviewing the SMAJ160CAQ-13-F datasheet, SMAJ160CAQ-13-F pinout, SMAJ160CAQ-13-F application, or SMAJ160CAQ-13-F equivalent, this device is selected for high-reliability 12V/24V automotive subsystems requiring AEC-Q101 qualification, IATF 16949 manufacturing, and validated clamping performance under repetitive surge stress.
Technical Context
This bi-directional TVS operates symmetrically across both polarities, with a breakdown voltage (VBR) of 178–197V at 1.0mA test current and <0.5µA reverse leakage at VRWM = 160V. Its glass-passivated junction ensures stable avalanche behavior under transient conditions defined by the 10×1000µs waveform per IEC 61000-4-5.
Thermally rated for -55°C to +175°C junction operation and packaged in UL 94V-0 molded plastic, it sustains 40A non-repetitive forward surge (8.3ms half-sine) while maintaining clamping integrity below 259V - critical for safeguarding 160V-rated power rails and signal lines in ADAS camera modules and gateway ECUs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400W - withstands ISO7637-2 Pulse 1 (-100V) and Pulse 3a (-150V) without failure |
| Reverse Standoff Voltage (VRWM) | 160V - sets minimum operating voltage threshold before clamping activation |
| Max Clamping Voltage (VC) | 259V @ IPP = 1.5A - limits downstream voltage stress during 10×1000µs transients |
| Breakdown Voltage (VBR) | 178–197V @ IT = 1.0mA - defines precise avalanche onset for predictable protection margin |
| Leakage Current (IR) | <0.5µA @ VRWM - ensures negligible standby power loss in always-on vehicle networks |
| Operating Temperature | -55°C to +175°C - supports under-hood placement in engine management systems |
| AEC-Q101 Qualified | Yes - certified for automotive use with PPAP documentation and change control |
Pinout & Package
Package: SMA (Surface-Mount Axial), molded plastic UL 94V-0 housing, cathode band omitted (bi-directional configuration). Terminals are matte tin-plated, solderable per MIL-STD-202 Method 208, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bi-directional avalanche terminals | No polarity dependency - connects inline with protected line regardless of DC bias direction |
| Case / Body | Non-conductive thermal path | Provides mechanical mounting and limited heat dissipation; no electrical connection |
Key Features
| Feature | Design Value |
|---|---|
| 400W peak pulse rating | Enables single-device protection against severe load dump and inductive switching surges in 24V commercial vehicle systems |
| Glass-passivated die construction | Delivers stable VBR tolerance and long-term reliability under thermal cycling in automotive environments |
| AEC-Q101 qualification & IATF 16949 manufacturing | Guarantees production consistency, traceability, and change control required for Tier-1 automotive supply chains |
| Bi-directional architecture | Eliminates orientation errors during SMT assembly and protects AC-coupled signals like CAN differential pairs |
| Halogen- and antimony-free "Green" design | Meets global environmental compliance (RoHS 3, ELV) without compromising surge robustness |
Applications
| Engine Control Unit (ECU) | Automotive Camera Module |
|---|---|
Use Scenario: Protects 12V power input and LIN bus pins from battery transients during cranking and alternator load dump. IC Role / Device Role: Primary overvoltage clamp on microcontroller power rail and communication interface. Use Value: Limits voltage excursion to ≤259V during ISO7637-2 Pulse 1 (-100V), preventing latch-up or permanent damage to 3.3V/5V logic. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bi-directional automotive TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160A-13-F | Uni-directional version; includes cathode band marking and forward voltage drop (~3.5V @ 35A) | Requires correct polarity alignment; unsuitable for AC or bidirectional signal lines like CAN | Select only when protecting unidirectional DC rails where polarity is fixed and forward conduction must be blocked |
| TPSMD160C | Same VRWM/VC specs but higher PM(AV) = 5W (vs. 1.0W); larger SMC package (7.1mm × 6.2mm) | Higher steady-state power handling enables use in thermally constrained locations without derating | Prefer when board layout allows SMC footprint and system requires >1W continuous dissipation capability |
Compared with SMAJ160CAQ-13-F, the uni-directional SMAJ160A-13-F demands strict orientation control, while TPSMD160C trades smaller SMA size for greater thermal mass and higher average power - making the AQ variant optimal for space-constrained, bidirectional, AEC-Q101–mandated designs.

FAQ
What does the 'C' suffix in SMAJ160CAQ-13-F indicate?
The 'C' denotes bi-directional functionality: the device clamps symmetrically for both positive and negative transients, eliminating polarity concerns during PCB layout and enabling use on AC-coupled buses like CAN differential pairs. It has no cathode band marking, unlike uni-directional variants such as SMAJ160A-13-F.
Is SMAJ160CAQ-13-F suitable for 24V commercial vehicle systems?
Yes - its 160V VRWM and 259V VC rating provide adequate margin above typical 24V nominal systems (up to ~32V during load dump), and it meets ISO7637-2 Pulse 1 (-100V) and Pulse 2a (+50V) requirements. The -55°C to +175°C operating range further supports under-hood deployment.
How does the AQ grade differ from standard SMAJ parts?
The AQ suffix indicates automotive qualification: AEC-Q101 stress testing, PPAP documentation readiness, IATF 16949 manufacturing, and enhanced traceability. Standard SMAJ parts lack these certifications and are intended for industrial or consumer use only.
Can SMAJ160CAQ-13-F replace SMAJ150CAQ-13-F in a design?
Only if the protected circuit's maximum working voltage is ≥160V - VRWM increases from 150V to 160V, raising the clamping threshold. Verify that downstream components tolerate the higher 243V → 259V VC and that ISO7637-2 Pulse 3a (-150V) margin remains sufficient with the elevated standoff.
