Product details
Overview
P6SMB13CAT3 from ON Semiconductor is a bidirectional 600 W transient voltage suppressor (TVS) diode designed for parallel overvoltage protection of sensitive electronics. It features a 11.1 V working peak reverse voltage (VRWM), 13.05 V nominal breakdown voltage (VBR) at 1 mA test current, and clamps transients to ≤18.2 V at 33 A peak pulse current - enabling robust surge suppression in power supply inputs and interface lines.
For engineers reviewing the P6SMB13CAT3 datasheet, pinout, applications, or equivalent options, key selection criteria include clamping voltage margin vs. system operating voltage, 600 W single-pulse surge capability, UL 497B recognition for isolated loop protection, low leakage (<5 µA @ 11.1 V), and SMB (DO-214AA) surface-mount compatibility with standard PCB footprints.
Technical Context
The P6SMB13CAT3 operates as a bidirectional Zener-based TVS, leveraging avalanche breakdown to clamp both positive and negative transients without polarity dependence. Its <1 ns response time and low dynamic impedance ensure rapid voltage limiting during ESD or lightning-induced surges.
Thermal design relies on junction-to-lead resistance of 40 °C/W and 600 W peak power rating at 1 ms pulse width (10/1000 µs waveform). Derating begins above 75°C lead temperature, with full power usable only at TL ≤ 75°C per datasheet Figure 3.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W @ 1 ms pulse - sustains single high-energy transients common in industrial power line surges |
| Working Peak Reverse Voltage (VRWM) | 11.1 V - maximum continuous DC or peak AC voltage the device blocks before clamping |
| Breakdown Voltage (VBR) | 12.4 V (max) @ 1 mA - defines onset of avalanche conduction; ensures reliable triggering above normal operating voltage |
| Clamping Voltage (VC) | 18.2 V @ 33 A IPP - maximum voltage seen by protected circuit during worst-case surge |
| Leakage Current (IR) | <5 µA @ 11.1 V - negligible standby power loss and signal integrity impact in high-impedance circuits |
| Junction Capacitance (Cj) | 740 pF @ 0 V - limits use in high-speed data lines but suitable for power rails and low-frequency interfaces |
| ESD Rating | Class 3 (>16 kV HBM) - meets IEC 61000-4-2 Level 4 for system-level ESD immunity |
| UL Recognition | UL 497B certified for isolated loop circuit protection - validates safety compliance in telecom and industrial isolation barriers |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13CA | Same VRWM (11.1 V) and VC (18.2 V), but lower 400 W peak power rating and SMA package (smaller footprint, higher thermal resistance) | Limited to lower-energy transients; less suitable for automotive load dump or industrial 4 kV surges | Select when board space is constrained and surge energy does not exceed 400 W capability |
| 1.5KE13CA | Same electrical specs but axial-leaded DO-201 package; higher thermal mass but through-hole mounting required | Not suitable for automated SMT assembly; used where mechanical robustness or manual repairability is prioritized | Select for prototyping, legacy designs, or environments requiring high vibration resistance and hand-soldering access |
Compared with SMAJ13CA and 1.5KE13CA, the P6SMB13CAT3 delivers optimal balance of 600 W surge handling, SMB surface-mount compatibility, and UL 497B certification - making it preferred for production-grade industrial and medical power rail protection where both performance and regulatory compliance are mandatory.

FAQ
What is the clamping voltage of the P6SMB13CAT3 under maximum surge conditions?
The P6SMB13CAT3 clamps to a maximum of 18.2 V when subjected to its rated peak pulse current of 33 A (10/1000 µs waveform). This value is measured per ON Semiconductor's test conditions and represents the highest voltage the protected circuit will experience during a worst-case transient event. The P6SMB13CAT3 maintains this clamping performance consistently across its qualified temperature range (−65°C to +150°C).
Is the P6SMB13CAT3 RoHS compliant and lead-free?
Yes, the "G" suffix in P6SMB13CAT3G confirms Pb-free construction per RoHS Directive 2011/65/EU. The device uses ON Semiconductor's Surmetic molded plastic package with lead-free terminations, qualified for reflow soldering up to 260°C for 10 seconds. The P6SMB13CAT3 meets JEDEC J-STD-020 moisture sensitivity level (MSL) 1 requirements.
Does the P6SMB13CAT3 require polarity-aware PCB layout?
No - the P6SMB13CAT3 is a bidirectional TVS diode with no anode/cathode distinction in circuit function. Its marking (13C) contains no polarity band, and it clamps symmetrically for both positive and negative transients. This eliminates orientation constraints during placement and reduces assembly errors in high-volume SMT production of the P6SMB13CAT3.
What is the maximum continuous reverse voltage the P6SMB13CAT3 can block?
The P6SMB13CAT3 has a working peak reverse voltage (VRWM) of 11.1 V - the highest DC or repetitive peak AC voltage it reliably blocks without entering breakdown. Operating above this value risks premature conduction and thermal runaway. Designers must ensure system operating voltage remains ≤11.1 V to maintain reliable blocking behavior of the P6SMB13CAT3.
How does the P6SMB13CAT3 compare to unidirectional TVS diodes in surge protection?
Unlike unidirectional TVS diodes such as P6SMB13AT3, the P6SMB13CAT3 provides symmetrical clamping for both polarities - essential for AC lines, floating grounds, or bidirectional data buses. Unidirectional variants offer slightly lower leakage but require correct polarity orientation and cannot protect against reverse-polarity transients. The P6SMB13CAT3 eliminates that risk entirely.
