Product details
Overview
SMAJ160AQ-13-F from Diodes Incorporated is a unidirectional 400W automotive transient voltage suppressor (TVS) diode with 160V reverse standoff voltage, 259V max clamping voltage at 1.5A peak pulse current, and AEC-Q101 qualification for under-hood power line protection in ISO7637-2 Pulse 1/2a/3a/3b-compliant systems.
For engineers reviewing the SMAJ160AQ-13-F datasheet, SMAJ160AQ-13-F pinout, SMAJ160AQ-13-F application, or SMAJ160AQ-13-F equivalent, key selection criteria include clamping voltage margin vs. system rail, IPP derating at elevated ambient temperature, unidirectional polarity alignment with DC bus topology, and IATF 16949 manufacturing traceability for automotive BOMs.
Technical Context
This TVS operates as a shunt-clamping device triggered by voltage exceeding VRWM = 160V, with breakdown occurring at 178–197V (IT = 1.0mA). Its glass-passivated junction ensures stable leakage (<0.5µA) and robust surge handling per ISO10605 (30kV contact/air discharge) and ISO7637-2 transient waveforms.
Designed for placement across DC power rails upstream of ECUs, it conducts transient energy into ground during 10/1000µs pulses, limiting voltage to ≤259V while dissipating up to 400W non-repetitively. Thermal design must account for PM(AV) = 1.0W at TL = +75°C and derating above TA = +25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400W - Sustains single 10×1000µs transients without failure |
| Reverse Standoff Voltage | 160V - Maximum continuous DC operating voltage before clamping onset |
| Clamping Voltage | 259V @ IPP = 1.5A - Limits downstream voltage during worst-case ISO7637-2 Pulse 1 (−100V) |
| Breakdown Voltage | 178–197V @ IT = 1.0mA - Confirmed avalanche initiation range for reliable triggering |
| Leakage Current | <0.5µA @ VRWM - Negligible standby power loss on 12V/24V automotive rails |
| Operating Temperature | −55°C to +175°C - Supports engine compartment mounting with full junction rating |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, cathode-banded unidirectional configuration. Molded plastic body (UL 94V-0), 0.064g mass, moisture sensitivity level 1.

Applications
| Engine Control Unit (ECU) Power Input | Body Control Module (BCM) CAN Bus Protection |
|---|---|
Use Scenario: 12V battery feed to microcontroller power supply in under-hood ECU exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Shunt TVS clamping transient overvoltage before LDO regulator input. Use Value: Limits voltage to ≤259V during ISO7637-2 Pulse 1 (−100V), protecting 3.3V/5V logic rails downstream. | Use Scenario: CAN_H/CAN_L lines connected to vehicle chassis ground in BCM with shared power domain. IC Role / Device Role / Timing Role: Bidirectional clamping on signal lines referenced to local ground. Use Value: Not applicable - SMAJ160AQ-13-F is unidirectional; requires SMAJ160CQ-13-F for bidirectional CAN protection. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160A-13-F | Non-automotive grade; lacks AEC-Q101 qualification and PPAP support | Not suitable for production automotive programs requiring change control and IATF 16949 traceability | Select only for non-automotive prototypes or cost-sensitive industrial designs |
| SMAJ170AQ-13-F | Higher VRWM (170V) and VCL (275V); same 400W rating and package | Better margin for 24V systems with higher nominal rail; tighter clamping ratio (1.62× vs. 1.61×) | Prefer when system nominal voltage exceeds 160V or additional clamping headroom is required |
Compared with SMAJ160A-13-F, the AQ variant adds automotive qualification and process control; compared with SMAJ170AQ-13-F, it offers lower clamping voltage for 12V-centric subsystems where 259V ceiling is critical for downstream component survival.

FAQ
What is the maximum clamping voltage of SMAJ160AQ-13-F at its rated peak pulse current?
The maximum clamping voltage is 259V at IPP = 1.5A, measured using the standardized 10×1000µs double-exponential waveform per IEC 61000-4-5. This value defines the upper voltage limit imposed on protected circuitry during worst-case transients like ISO7637-2 Pulse 1.
Is SMAJ160AQ-13-F suitable for bidirectional signal line protection such as CAN or LIN buses?
No - SMAJ160AQ-13-F is unidirectional, indicated by the absence of "C" in its part number. For bidirectional protection on differential buses, the SMAJ160CQ-13-F variant must be used, which features symmetrical clamping for both polarities and matches the same 400W rating and AEC-Q101 qualification.
How does the thermal derating of SMAJ160AQ-13-F affect its steady-state power dissipation?
Its steady-state power dissipation is rated at 1.0W at lead temperature TL = +75°C, with linear derating to zero at TL = +175°C. Ambient temperature derating follows Figure 1 in DS40739: at TA = +125°C, pulse power capability drops to ~60% of 400W, requiring layout optimization for heatsinking and airflow in enclosed engine bay locations.
What packaging and reel specifications apply to SMAJ160AQ-13-F?
SMAJ160AQ-13-F ships in tape-and-reel format with 5,000 units per reel (EIA-481-D compliant). The "-13-F" suffix denotes 8mm carrier tape, 4mm pocket pitch, and RoHS-compliant matte tin plating. Reel dimensions follow standard JEDEC J-STD-033 for moisture sensitivity level 1 handling.
