Product details
Overview
SMAJ160CA-13-F from Diodes Incorporated is a bidirectional 400W surface-mount transient voltage suppressor (TVS) diode designed for overvoltage protection in DC power lines and signal interfaces. It features a 160V reverse standoff voltage (VRWM), 178–197V breakdown range (VBR), 259V maximum clamping voltage (VC) at 1.5A peak pulse current (IPP), and operates across –55°C to +150°C. Used in automotive infotainment power rails and industrial sensor I/O protection.
For engineers reviewing the SMAJ160CA-13-F datasheet, SMAJ160CA-13-F pinout, SMAJ160CA-13-F application, or SMAJ160CA-13-F equivalent, key selection criteria include clamping voltage margin relative to system rail, unidirectional vs. bidirectional polarity requirements, thermal derating above +25°C, and compliance with AEC-Q101 for automotive-grade surge immunity.
Technical Context
This bidirectional TVS diode uses glass-passivated junction construction to achieve fast response time (<1 ns) and stable clamping under 10/1000 µs surge waveforms. Its symmetrical I-V characteristic enables protection against both positive and negative transients without external polarity management.
Designed for placement directly at board-level I/O or power entry points, it handles up to 40A peak forward surge current (IFSM) and dissipates 1.0W steady-state power at lead temperature TL = +75°C. Thermal performance is validated per J-STD-020 Level 1 moisture sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400 W - Sustains single 10/1000 µs surges up to this level without failure |
| Reverse Standoff Voltage (VRWM) | 160 V - Maximum continuous DC or RMS voltage before significant leakage |
| Breakdown Voltage (VBR) | 178–197 V @ IT = 1.0 mA - Confirmed conduction onset window for design margining |
| Clamping Voltage (VC) | 259 V @ IPP = 1.5 A - Maximum voltage seen by protected circuit during rated surge |
| Peak Pulse Current (IPP) | 1.5 A - Surge current level at which VC is specified; correlates to IEC 61000-4-5 Level 3 immunity |
| Operating Temperature | –55°C to +150°C - Validated junction temperature range for under-hood and industrial environments |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, molded plastic case with UL 94V-0 flammability rating; cathode band omitted due to bidirectional configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional transient path | Either terminal serves as input/output; no polarity dependency in layout |
| Case | Thermal and mechanical interface | Exposed copper pad on bottom aids heat dissipation; requires solder mask defined footprint |
Key Features
| Feature | Design Value |
|---|---|
| 400W peak pulse power | Enables robust protection against IEC 61000-4-5 10/1000 µs surges up to 400W without degradation |
| Glass-passivated die | Ensures stable VBR and low leakage (<5 µA) over lifetime and temperature cycling |
| RoHS-compliant & halogen-free | Meets EU RoHS 3 (2015/863/EU) and automotive "Green" standards (<900 ppm Br/Cl, <1000 ppm Sb) |
| J-STD-020 Level 1 moisture sensitivity | Allows unlimited floor life and standard reflow without baking preconditioning |
Applications
| Automotive Infotainment Power Rail | Industrial CAN Bus Interface |
|---|---|
Use Scenario: Protects 12V supply inputs of head units and display modules from load dump and alternator ripple. IC Role / Device Role / Timing Role: Primary clamping device placed between fuse and DC-DC converter input. Use Value: Clamps transients to ≤259V, preserving downstream regulators rated for 36V absolute max. |
Use Scenario: Shields CANH/CANL lines in factory automation nodes from ESD and inductive switching noise. IC Role / Device Role / Timing Role: Bidirectional shunt element mounted at connector entry point. Use Value: Symmetric clamping ensures equal protection for both differential signal polarities without added components. |
| Telecom Remote Radio Unit (RRU) | Smart Meter AC/DC Power Input |
Use Scenario: Guards 48V DC power feed to outdoor RRU enclosures exposed to lightning-induced surges. IC Role / Device Role / Timing Role: First-stage TVS in multi-tiered protection scheme ahead of MOV and gas discharge tube. Use Value: Fast <1 ns response captures initial surge edge before slower devices activate, reducing let-through energy. |
Use Scenario: Secures auxiliary 5V/12V logic supply derived from mains-connected SMPS in utility meters. IC Role / Device Role / Timing Role: Secondary clamping device after primary MOV, absorbing residual high-frequency overshoot. Use Value: Low clamping ratio (VC/VRWM ≈ 1.62) minimizes stress on LDOs and microcontroller I/O. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160CA from Littelfuse (SP0503BAHT) | Same VRWM (160V), but lower PPK (300W); higher VC (275V @ 1.5A) | Marginally lower surge handling; less suitable for IEC 61000-4-5 Level 4 | Select when cost sensitivity outweighs 100W peak power headroom |
| P6SMB160CA from Vishay | Identical VRWM and PPK, but larger SMB package (higher thermal mass); 20% higher typical VF | Requires larger PCB area; better sustained power dissipation at elevated ambient | Prefer for high-reliability industrial designs where board space permits larger footprint |
Compared with SMAJ160CA-13-F, SP0503BAHT trades 100W peak power for lower unit cost and broader distributor stock, while P6SMB160CA offers superior thermal stability in continuous surge environments at the expense of PCB real estate.

FAQ
What is the meaning of the 'C' suffix in SMAJ160CA-13-F?
The 'C' denotes bidirectional configuration: the device provides symmetrical clamping for both positive and negative voltage transients without polarity orientation constraints. This differs from unidirectional variants (e.g., SMAJ160A), which require correct anode/cathode placement and only clamp one polarity.
Can SMAJ160CA-13-F be used in place of a unidirectional TVS in a DC power line?
Yes, but with trade-offs: bidirectional operation introduces ~0.7V forward drop in both directions, increasing conduction loss during normal operation. For pure DC rails, unidirectional versions offer lower leakage and tighter clamping margin-bidirectional use is preferred only where AC-coupled signals or dual-polarity surges are expected.
What is the significance of the '-13-F' suffix in the part number?
'-13-F' specifies tape-and-reel packaging: 5,000 units per reel, 8 mm carrier tape width, EIA-481 compliant format, and matte tin lead finish. The 'F' confirms RoHS-compliant, lead-free plating per Diodes' internal specification DIO-001.
How does the clamping voltage of 259V relate to system-level surge testing?
At 1.5A IPP, 259V clamping ensures protected circuits see voltage limited to this value during standardized 10/1000 µs surges. For IEC 61000-4-5 Level 3 (1kV line-to-ground), this corresponds to ~1.5A let-through current into a 500Ω source impedance-validating suitability for industrial and automotive Class III immunity requirements.
