Product details
Overview
SMAJ130CA-13-F from Diodes Incorporated is a bidirectional 400W transient voltage suppressor (TVS) diode in SMA package, designed for primary overvoltage protection of DC power rails and signal lines. It features 130V reverse standoff voltage (VRWM), 144–159V breakdown voltage (VBR), 209V maximum clamping voltage (VC) at 1.9A peak pulse current (IPP), and operates across –55°C to +150°C ambient range - used in automotive infotainment power inputs and industrial PLC I/O modules.
For engineers reviewing the SMAJ130CA-13-F datasheet, SMAJ130CA-13-F pinout, SMAJ130CA-13-F application, or SMAJ130CA-13-F equivalent, key selection criteria include clamping voltage margin relative to protected IC VCC, unidirectional vs. bidirectional polarity requirements for AC-coupled interfaces, thermal derating above +25°C, and compliance with IEC 61000-4-2/4-5 surge immunity standards.
Technical Context
This bidirectional TVS diode uses glass-passivated junction construction to achieve fast response time (<1 ns) and stable clamping under 8.3 ms half-sine surge pulses. Its symmetrical avalanche structure enables equal clamping in both polarities, supporting AC line and differential bus protection without external polarity management.
Designed for surface-mount assembly on PCBs with minimal parasitic inductance, it delivers 400W non-repetitive peak pulse power dissipation at TA = +25°C, with linear derating to ~250W at +75°C and full functionality up to TJ = +150°C - critical for under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 400 W - sustains single 8.3 ms surge events per IEC 61000-4-5 without failure |
| Reverse Standoff Voltage | 130 V - maximum continuous DC or RMS AC voltage before significant leakage |
| Breakdown Voltage | 144–159 V @ 1.0 mA - guaranteed avalanche initiation window for predictable clamping onset |
| Clamping Voltage | 209 V @ 1.9 A IPP - limits transient voltage seen by downstream circuitry during surge |
| Leakage Current | 5.0 µA @ VRWM - negligible standby power loss in high-impedance monitoring circuits |
| Operating Temperature | –55°C to +150°C - qualified for under-dash automotive and industrial control cabinet use |

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130CA from Littelfuse (part # SMAJ130CA) | Identical VRWM (130 V), VBR (144–159 V), VC (209 V), but rated for 1.0 µA IR @ VRWM (vs. 5.0 µA) | Lower leakage supports ultra-low-power battery-backed sensors where standby current is critical | Select when sub-µA leakage is required; verify compatibility with existing layout and thermal profile |
| P6SMB130CA from Vishay (part # P6SMB130CA) | Same 130 V VRWM and bidirectional configuration, but larger SMB package (higher thermal mass, 600 W PPK) | Higher surge capacity suits 24 V industrial controls exposed to repeated switching transients | Choose for higher reliability margin in high-cycle environments; requires PCB pad revision |
Compared with SMAJ130CA-13-F, Littelfuse's SMAJ130CA offers tighter leakage control for low-power designs, while Vishay's P6SMB130CA trades compact size for greater thermal robustness and surge handling - making each suitable for distinct reliability or space-constrained design priorities.

FAQ
What does the "C" suffix in SMAJ130CA-13-F indicate?
The "C" denotes a bidirectional configuration: the device clamps symmetrically for both positive and negative transients, with no polarity marking on the SMA package. This differs from unidirectional variants (e.g., SMAJ130A), which feature a cathode band and only clamp in one direction. Bidirectional operation is required for AC-coupled lines and differential buses.
Can SMAJ130CA-13-F be used in place of a unidirectional TVS in a DC power rail?
Yes, but with trade-offs: bidirectional devices exhibit identical clamping in both directions, so they will conduct during normal reverse-bias conditions if the rail can swing negative - potentially causing excessive leakage or latch-up. For pure DC rails, unidirectional types are preferred unless intentional AC tolerance is needed.
How does the 400W rating translate to real-world surge immunity?
The 400W rating corresponds to a single 8.3 ms half-sine surge at TA = +25°C, such as IEC 61000-4-5 Combination Wave (1.2/50 µs voltage, 8/20 µs current). At 130 V VRWM, this supports up to ~1.9 A peak current - sufficient for Level 3 (2 kV) and Level 4 (4 kV) testing on 12–48 V systems when properly laid out.
Is SMAJ130CA-13-F qualified to AEC-Q200?
No - the standard SMAJ130CA-13-F is not AEC-Q200 qualified. Diodes offers an automotive-compliant variant under separate datasheet: SMAJ130CAQ-13-F, manufactured in IATF 16949-certified facilities and PPAP-capable. For automotive production, the "Q" suffix part must be specified to meet qualification requirements.
