Product details
Overview
P6SMB130AT3 from ON Semiconductor is a unidirectional 600 W transient voltage suppressor (TVS) diode designed for overvoltage protection in DC power rails and signal lines. It features a 111 V working peak reverse voltage (VRWM), 130.5 V nominal breakdown voltage (VBR) at 1 mA test current, 179 V maximum clamping voltage (VC) at 130 A peak pulse current (IPP), and <1 ns response time. It is used in industrial power supplies to safeguard rectifier outputs against lightning-induced surges.
For engineers reviewing the P6SMB130AT3 datasheet, pinout, applications, or equivalent options, key selection criteria include VRWM margin above operating voltage, VC vs. protected device's absolute maximum rating, thermal derating above 75°C, and UL 497B certification for isolated loop protection compliance.
Technical Context
The P6SMB130AT3 operates as a Zener-based avalanche clamp, conducting only when reverse voltage exceeds its specified VBR threshold. Its low zener impedance ensures stable clamping under high-energy transients, while its thermally robust SURMETIC® SMB package enables reliable junction-to-lead heat transfer (RJL = 40 °C/W).
It complies with UL 497B for isolated loop circuit protection and meets Class 3 ESD immunity (>16 kV HBM). The device exhibits negligible capacitance (3.3 pF at 0 V bias, 1 MHz), making it suitable for high-speed data line protection without signal integrity degradation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130A | Same SMB package, identical VRWM (111 V) and VC (179 V), but lower peak power (600 W same), different marking and traceability | No UL 497B recognition; lacks isolated loop protector classification | Select when UL certification is not required and cost sensitivity outweighs safety compliance needs |
| 1.5SMC130A | Higher package thermal resistance (RJA = 1.1 °C/W vs. 226 °C/W), larger SMC case (7.1 × 6.2 mm vs. 4.6 × 3.95 mm), same electrical specs | Better PCB heat spreading but requires 3× footprint area; unsuitable for space-constrained layouts | Select when board-level thermal management prioritizes junction cooling over size constraints |
Compared with SMBJ130A and 1.5SMC130A, the P6SMB130AT3 uniquely combines UL 497B certification, compact SMB footprint, and validated 600 W surge capability-making it the preferred choice for safety-critical, space-limited industrial and medical power systems.

FAQ
What is the maximum clamping voltage of the P6SMB130AT3 at its rated peak pulse current?
The P6SMB130AT3 has a maximum clamping voltage (VC) of 179 V at its rated peak pulse current (IPP) of 130 A, measured using the standard 10/1000 µs double-exponential waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case surge events and must be compared directly against the absolute maximum ratings of downstream components to ensure safe operation. The P6SMB130AT3 maintains this clamping performance across its qualified temperature range of −65°C to +150°C.
Does the P6SMB130AT3 meet UL safety standards for isolated loop protection?
Yes, the P6SMB130AT3 is UL Recognized under file E210057 for protector classification QVGQ2 per UL 497B, specifically validating its use in isolated loop circuits. This certification confirms successful completion of strike voltage breakdown, endurance conditioning, dielectric voltage-withstand, and discharge testing-going beyond basic flammability requirements. The P6SMB130AT3's UL 497B status is documented in ON Semiconductor's official P6SMB6.8AT3 Series datasheet Rev. 10 and applies explicitly to all "G"-suffix variants including P6SMB130AT3.
What is the junction capacitance of the P6SMB130AT3 and how does it affect high-speed signal lines?
The P6SMB130AT3 exhibits a typical junction capacitance of 3.3 pF at 0 V bias and 1 MHz, measured at 25°C. This low capacitance minimizes signal distortion and rise-time degradation on high-speed interfaces such as CAN FD (5 Mbps), RS-485, or Ethernet PHY lines-enabling placement directly at connector entry points without compromising data integrity. The P6SMB130AT3's capacitance remains stable across its operating voltage range, ensuring consistent protection behavior during both steady-state and transient conditions.
How does the thermal performance of the P6SMB130AT3 compare between junction-to-lead and junction-to-ambient paths?
The P6SMB130AT3 has a junction-to-lead thermal resistance (RJL) of 40 °C/W, enabling 3.0 W continuous power dissipation at 75°C lead temperature, while its junction-to-ambient resistance (RJA) is 226 °C/W-limiting ambient-referenced dissipation to 0.55 W at 25°C. This disparity highlights the critical importance of PCB copper pour and thermal vias under the SMB package's exposed lead frame to realize the higher RJL-rated performance. The P6SMB130AT3's design assumes proper thermal land pattern per Case 403A footprint specifications to achieve published derating curves.
Is the P6SMB130AT3 suitable for bidirectional transient suppression applications?
No, the P6SMB130AT3 is a unidirectional TVS diode intended only for DC or single-polarity signal line protection. Bidirectional operation requires symmetrical clamping in both polarities, which this device does not provide. For bidirectional protection at comparable voltage ratings, ON Semiconductor specifies separate part numbers such as P6SMB130CAT3 (C = bidirectional); the P6SMB130AT3's datasheet explicitly states "*Please see P6SMB11CAT3 to P6SMB91CAT3 for Bidirectional devices" and marks the "A" suffix as unidirectional. Using P6SMB130AT3 in AC-coupled or bipolar signal paths risks catastrophic failure during negative transients.
