Product details
Overview
SMBJ130AQ-13-F from Diodes Incorporated is a unidirectional 130V standoff automotive transient voltage suppressor (TVS) diode in SMB package, rated for 600W peak pulse power, 209V clamping voltage at 2.9A IPP, and AEC-Q101 qualified for ISO7637-2 Pulse 1/2a/3a/3b and ISO10605 ESD protection in vehicle power line interfaces.
For engineers reviewing the SMBJ130AQ-13-F datasheet, SMBJ130AQ-13-F pinout, SMBJ130AQ-13-F application, or SMBJ130AQ-13-F equivalent, key selection criteria include clamping voltage margin vs. system rail, IPP derating under repetitive surge conditions, thermal management at TL = +75°C, and compliance with automotive change control and PPAP requirements.
Technical Context
This TVS operates as a unidirectional clamping device-cathode-anode polarity-triggering avalanche breakdown above VRWM = 130V to shunt transients away from downstream circuitry. Its 209V clamping voltage (VC) at 2.9A IPP ensures robust overvoltage protection for 12V/24V automotive subsystems during ISO7637-2 Pulse 1 (−150V), Pulse 2a (+112V), Pulse 3a (−220V), and Pulse 3b (+150V) events.
Designed for surface-mount deployment on power rails, it features a low 0.5µA max reverse leakage at VRWM, 3.5V forward voltage at 35A, and thermal stability across −55°C to +175°C junction temperature range-enabling placement near ECUs, body controllers, and infotainment power inputs without derating penalties below +75°C lead temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 130V - Maximum continuous reverse operating voltage before clamping begins; sets minimum system rail margin for 24V nominal systems. |
| VBR (min) | 144V - Breakdown initiates no earlier than this voltage, ensuring reliable turn-on only during defined surges. |
| VC @ IPP | 209V - Clamped voltage at 2.9A peak pulse current; defines maximum stress imposed on protected ICs during ISO7637-2 Pulse 3a. |
| PPK | 600W - Peak pulse power handling per 10×1000µs waveform; supports single-event surge suppression without failure. |
| IFSM | 100A - Surge current rating for 8.3ms half-sine wave; validates robustness against load dump and inductive switching events. |
| TJ Range | −55°C to +175°C - Full automotive temperature operation without parameter drift or reliability degradation. |
| PM(AV) | 5.0W - Steady-state power dissipation limit at TL = +75°C; determines PCB copper area and thermal pad design for continuous fault conditions. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, molded plastic UL 94V-0, 0.1g weight, moisture sensitivity level 1. Cathode band marked on top surface for polarity identification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or low-impedance return path; establishes clamping reference for unidirectional operation. |
| Cathode | High-side surge input | Connected to protected line (e.g., battery feed); avalanche conduction occurs from cathode to anode during overvoltage. |
Key Features
| Feature | Design Value |
|---|---|

| Lead-free & halogen-free | Matte tin plating, RoHS 3 compliant, <900ppm Br/Cl, <1000ppm Sb-supports green manufacturing and end-of-life recycling mandates. |
| 600W peak pulse rating | Handles high-energy transients such as ISO7637-2 Pulse 1 (−150V) and Pulse 3a (−220V) without parametric shift or catastrophic failure. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional automotive TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A-13-F | No AEC-Q101 qualification; standard industrial grade; identical electrical specs and SMB package. | Lacks PPAP documentation and automotive change control; unsuitable for Tier 1 production BOMs requiring IATF 16949 traceability. | Select only for non-automotive prototypes or cost-sensitive industrial designs where AEC-Q101 is not mandated. |
| TPSMAJ130A-Q | Same VRWM/VC/PPK ratings; SOD-123FL package (smaller footprint, lower thermal mass); AEC-Q101 qualified. | Lower PM(AV) = 3.0W limits steady-state surge handling; requires tighter thermal layout for repeated pulse scenarios. | Prefer when board space is constrained and single-pulse protection dominates; verify thermal performance under multi-pulse duty cycles. |
Compared with SMBJ130A-13-F, the SMBJ130AQ-13-F adds mandatory automotive qualification and supply chain controls; versus TPSMAJ130A-Q, it trades smaller size for higher thermal robustness and proven 5W steady-state dissipation in SMB layout.

FAQ
What is the polarity configuration of SMBJ130AQ-13-F?
SMBJ130AQ-13-F is a unidirectional TVS diode with cathode-anode polarity, indicated by a visible cathode band on the SMB package top surface. It conducts only during reverse overvoltage events-forward bias behaves like a standard silicon diode with VF ≈ 3.5V at 35A-and must be oriented with cathode toward the protected line and anode to ground.
Does SMBJ130AQ-13-F meet ISO7637-2 Pulse 3a requirements?
Yes. With a clamping voltage VC = 209V at IPP = 2.9A and 600W peak pulse rating, SMBJ130AQ-13-F suppresses ISO7637-2 Pulse 3a (−220V, 50Ω source) to within safe limits for 24V automotive systems. Its 130V VRWM provides adequate margin above nominal rail, and its 100A IFSM withstands repetitive 8.3ms surges without degradation.
How does the "AQ" suffix differ from standard "A" in SMBJ130A-13-F?
The "AQ" suffix denotes AEC-Q101 qualification, PPAP capability, and manufacture in IATF 16949-certified facilities-mandatory for automotive production. Electrically identical to SMBJ130A-13-F, the AQ variant includes controlled change management, lot-level traceability, extended reliability testing (HTOL, TC, UHAST), and formal documentation required by Tier 1 suppliers.
Can SMBJ130AQ-13-F be used in parallel for higher surge current handling?
No-parallel connection is not recommended due to mismatched avalanche characteristics causing current imbalance and premature failure of one device. For higher IPP, select a single higher-rated TVS (e.g., SMBJ150AQ-13-F) or use a TVS array with matched channels. Layout symmetry and thermal coupling do not compensate for inherent VBR tolerances (±5%) across discrete units.
