Product details
Overview
P6SMB130CA from Taiwan Semiconductor is a bidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a standoff voltage of 111 V, breakdown voltage range of 124–137 V, and clamping voltage of 179 V at 3.5 A peak pulse current. It features glass-passivated junction, low leakage (<1 µA at 111 V), and meets ISO 7637-2 Pulse 1/2a/2b/3a/3b for automotive surge immunity. It protects DC power rails in switching mode power supplies and adapters.
For engineers reviewing the P6SMB130CA datasheet, P6SMB130CA pinout, P6SMB130CA application, or P6SMB130CA equivalent, key selection criteria include bidirectional clamping capability, DO-214AA (SMB) package compatibility, 150°C junction rating, thermal resistance (RθJA = 55°C/W), and compliance with automotive transient standards.
Technical Context
The P6SMB130CA operates as a bidirectional avalanche diode, symmetrically clamping voltage transients in both polarities. Its glass-passivated junction ensures stable breakdown characteristics and low leakage, while its 600W peak pulse power rating (10/1000 µs waveform) supports robust surge handling in harsh environments.
Designed for surface-mount assembly on PCBs, it delivers fast response time (<1.0 ps from 0 V to VBR min) and complies with JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1. Thermal performance is characterized by RθJC = 10°C/W and RθJA = 55°C/W.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ130CA (Bourns) | Same DO-214AA package, identical VWM/VBR/VC specs, but higher typical IR (5 µA vs. <1 µA) | Suitable where ultra-low leakage is not critical; slightly lower surge lifetime endurance | Preferred when Bourns supply chain alignment or legacy design reuse is required |
| 1.5SMC130CA (ON Semiconductor) | Same electrical specs and SMB package, but rated for 1500 W peak power (10/1000 µs); larger thermal mass | Better suited for high-repetition surge environments; requires same PCB footprint but higher thermal relief | Select when extended surge cycling or higher ambient temperatures (>85°C) demand extra margin |
Compared with P6SMB130CA, SMBJ130CA offers equivalent clamping performance with relaxed leakage tolerance, while 1.5SMC130CA provides higher pulse power headroom in the same footprint-enabling drop-in use where thermal design allows.

FAQ
What is the maximum clamping voltage of the P6SMB130CA under standard 10/1000 µs surge conditions?
The P6SMB130CA has a maximum clamping voltage (VC) of 179 V at 3.5 A peak pulse current (IPPM) under the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuits during surge events. The P6SMB130CA maintains this clamping performance across its full operating temperature range (−55°C to +150°C).
Is the P6SMB130CA suitable for bidirectional signal line protection?
Yes, the P6SMB130CA is explicitly designed for bidirectional transient suppression, as indicated by the "CA" suffix and confirmed in the datasheet's "Devices for Bipolar Applications" section. Its symmetrical VBR and VC characteristics in both polarities make it appropriate for protecting AC-coupled interfaces, differential buses, or floating DC rails where polarity reversal may occur. The P6SMB130CA does not require external polarity configuration.
Does the P6SMB130CA meet automotive surge immunity standards?
Yes, the P6SMB130CA meets ISO 7637-2 requirements for Pulse 1, 2a, 2b, 3a, and 3b, which cover common automotive transient threats including load dump, alternator ripple, and inductive switching. This compliance is explicitly stated in the "Features" section of the official Taiwan Semiconductor datasheet (Version Q2209). The P6SMB130CA is routinely deployed in automotive body control modules and infotainment power supplies.
What is the thermal resistance from junction to ambient for the P6SMB130CA in standard PCB mounting?
The junction-to-ambient thermal resistance (RθJA) of the P6SMB130CA is 55°C/W under standard JEDEC test conditions (single-layer 1 in² copper pad). This value assumes the DO-214AA (SMB) package is mounted on a typical FR-4 PCB with recommended pad layout per the datasheet. For high-power or high-temperature applications, thermal relief via additional copper area or internal planes can reduce effective RθJA; the P6SMB130CA's RθJC is 10°C/W.
How does the P6SMB130CA compare to the unidirectional P6SMB130A in terms of electrical performance?
The P6SMB130CA and P6SMB130A share identical VWM (111 V), VBR (124–137 V), VC (179 V), and PPPSM (600 W) ratings, but differ in polarity: P6SMB130CA is bidirectional, while P6SMB130A is unidirectional. The P6SMB130CA clamps equally in both directions, making it suitable for AC or polarity-agnostic DC rails; P6SMB130A requires correct orientation relative to ground. Both use the same DO-214AA package and marking code NGJ.
