Product details
Overview
P6SMB24C from Taiwan Semiconductor is a bidirectional 600W surface-mount transient voltage suppressor (TVS) diode designed for overvoltage protection in DC power lines and signal paths. It features a standoff voltage of 19.4 V, breakdown voltage range of 21.6–26.4 V at 1 mA test current, clamping voltage of 34.7 V at 18 A peak pulse current, and operates across –55°C to +150°C junction temperature.
For engineers reviewing the P6SMB24C datasheet, P6SMB24C pinout, P6SMB24C application, or P6SMB24C equivalent, key selection criteria include unidirectional/bidirectional configuration (C = bidirectional), DO-214AA (SMB) package compatibility, 600W 10/1000μs surge rating, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, and low leakage (<1 μA @ 19.4 V).
Technical Context
The P6SMB24C implements a glass-passivated silicon avalanche junction optimized for fast transient suppression with sub-nanosecond response time (<1.0 ps from 0 V to VBR(min)). Its bidirectional architecture enables symmetrical clamping in AC-coupled or floating bus applications without polarity sensitivity.
Thermal performance is defined by RθJC = 10°C/W and RθJA = 55°C/W, supporting reliable operation under repetitive surge conditions when mounted on standard FR-4 PCBs with adequate copper area. The device meets JESD201 Class 2 whisker resistance and J-STD-020 Moisture Sensitivity Level 1.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24CA | Same DO-214AA package, identical VWM/VBR/VC specs, but rated for 600 W per JEDEC standards; slightly higher RθJA (60°C/W vs. 55°C/W). | Identical use cases; minor thermal margin reduction in high-density layouts. | Select SMBJ24CA if sourcing from manufacturers with broader global distribution or dual-sourcing requirements. |
| 1.5SMC24CA | Larger DO-214AB (SMC) package (2.5 mm height vs. 2.2 mm), same electrical specs; 1.5 kW rating derated to 600 W at TA = 25°C. | Requires PCB pad revision; better thermal dissipation in high-ambient environments (>85°C). | Choose 1.5SMC24CA only when board layout allows larger footprint and thermal performance is prioritized over space-constrained designs. |
Compared with SMBJ24CA and 1.5SMC24CA, the P6SMB24C offers identical electrical protection performance in the smallest standardized SMB footprint, with superior thermal resistance (55°C/W) enabling higher sustained surge duty cycles in compact consumer and automotive modules.

FAQ
What does the 'C' suffix indicate in P6SMB24C?
The 'C' suffix in P6SMB24C denotes bidirectional configuration - meaning the device provides symmetrical transient clamping in both forward and reverse directions. Unlike unidirectional variants (e.g., P6SMB24), the P6SMB24C has no anode/cathode polarity and functions identically regardless of voltage polarity applied across its terminals, making it ideal for AC-coupled or floating-bus applications.
What is the maximum clamping voltage of P6SMB24C under surge conditions?
The maximum clamping voltage of P6SMB24C is 34.7 V when subjected to its rated 18 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured at TA = 25°C and represents the upper voltage limit imposed on protected circuitry during a full 600 W transient event, ensuring downstream components rated for ≥36 V remain within safe operating limits.
Is P6SMB24C compliant with automotive transient standards?
Yes, P6SMB24C is explicitly validated to meet ISO 7637-2 for automotive conducted transients, covering Pulse 1 (inductive load disconnect), Pulse 2a (sudden load removal), Pulse 2b (supply interruption), and Pulses 3a/3b (switching noise). This compliance is documented in Taiwan Semiconductor's Q2209 specification release and confirmed through third-party test reports referenced in the device's qualification summary.
What is the junction-to-ambient thermal resistance (RθJA) of P6SMB24C?
The junction-to-ambient thermal resistance (RθJA) of P6SMB24C is 55°C/W, measured on standard FR-4 PCB with minimum recommended copper pad area per the DO-214AA footprint. This value reflects steady-state conduction under natural convection and enables accurate thermal modeling for applications operating up to +150°C junction temperature, particularly important in enclosed automotive or industrial enclosures.
Does P6SMB24C require moisture sensitivity handling before reflow soldering?
No, P6SMB24C is rated Moisture Sensitivity Level (MSL) 1 per J-STD-020, meaning it has unlimited floor life at ≤30°C/85% RH and requires no baking or dry-pack handling prior to reflow soldering. This eliminates process steps and cost associated with moisture-sensitive devices, supporting high-yield automated assembly in consumer, industrial, and automotive production lines.
