Product details
Overview
P6SMB82C from Taiwan Semiconductor is a bidirectional 600W surface-mount transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, with a minimum breakdown voltage of 73.8 V, maximum clamping voltage of 118 V at 5.3 A peak pulse current, and stand-off voltage of 66.4 V. It protects DC power rails in switching mode power supplies, adapters, and display electronics against ESD and surge events per ISO 7637-2 Pulse 1/2a/2b/3a/3b.
For engineers reviewing the P6SMB82C datasheet, P6SMB82C pinout, P6SMB82C application, or P6SMB82C equivalent, key selection criteria include unidirectional vs. bidirectional configuration (C suffix = bidirectional), clamping performance under 10/1000 µs transients, thermal resistance (RθJA = 55 °C/W), and compliance with J-STD-020 moisture sensitivity level 1.
Technical Context
The P6SMB82C is a glass-passivated, single-die, bidirectional TVS diode optimized for fast transient suppression in automotive and industrial DC systems. Its junction-to-ambient thermal resistance of 55 °C/W and 150 °C maximum junction temperature support operation in thermally constrained PCB layouts without forced cooling.
It delivers 118 V clamping voltage at 5.3 A (10/1000 µs waveform), with <1 µA reverse leakage at 66.4 V and a typical response time under 1.0 ps - enabling protection of sensitive downstream circuitry such as DC-DC controllers and interface ICs against fast-rising transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 73.8 V / 90.2 V - ensures reliable triggering above system operating voltage while avoiding false trips during normal ripple or load transients |
| VWM | 66.4 V - maximum continuous reverse working voltage compatible with 48–60 V nominal DC bus applications |
| VC @ IPPM | 118 V - clamping voltage limits stress on protected ICs during 600 W surge events (10/1000 µs) |
| IPPM | 5.3 A - peak pulse current capacity defines maximum energy absorption before failure |
| RθJA | 55 °C/W - enables thermal design margin for 3 W steady-state dissipation in standard FR-4 layouts |
| TJ(max) | +150 °C - supports operation in under-hood or enclosed industrial enclosures without derating |
| Moisture Sensitivity | Level 1 (J-STD-020) - allows standard SMT reflow without baking or special handling |
Pinout & Package
DO-214AA (SMB) surface-mount package with cathode band marking; matte tin-plated leads compliant with J-STD-002 solderability; weight ≈ 0.090 g; UL 94V-0 molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ82CA | Same DO-214AA package, identical VBR (73.8–90.2 V), but higher VC = 125 V at 5.0 A; RθJA = 60 °C/W | Marginally lower clamping performance; less suitable for 75 V-rated downstream components | Select P6SMB82C when tighter clamping (<118 V) and lower thermal resistance (55 °C/W) are required for high-reliability 48 V systems |
| 1.5SMC82CA | Higher power rating (1500 W), larger DO-214AB (SMC) package, VC = 113 V at 13.3 A; not drop-in compatible | Requires PCB redesign; suited for higher-energy surge environments (e.g., outdoor PoE switches) | Choose P6SMB82C for space-constrained SMB footprints where 600 W suffices and layout reuse is critical |
Compared with SMBJ82CA and 1.5SMC82CA, the P6SMB82C offers superior thermal performance (55 °C/W vs. 60/75 °C/W) and tighter clamping (118 V vs. 125/113 V), making it optimal for compact, thermally demanding 48–60 V DC systems requiring precise voltage limiting without board rework.

FAQ
What does the 'C' suffix indicate in P6SMB82C?
The 'C' suffix in P6SMB82C denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression in both forward and reverse directions. Unlike unidirectional variants (e.g., P6SMB82), the P6SMB82C has no polarity-dependent function and is marked with a cathode band solely for mechanical orientation - critical for protecting AC-coupled or floating-rail circuits where voltage polarity may reverse.
What is the maximum clamping voltage of P6SMB82C and under what test condition?
The maximum clamping voltage of P6SMB82C is 118 V, measured at a peak pulse current (IPPM) of 5.3 A using the standardized 10/1000 µs double-exponential surge waveform. This value is guaranteed across the full operating temperature range (−55 °C to +150 °C) and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Is P6SMB82C compliant with automotive surge standards?
Yes, P6SMB82C meets ISO 7637-2 requirements for Pulse 1 (inductive load disconnect), Pulse 2a (sudden load removal), Pulse 2b (supply interruption), Pulse 3a (switching noise), and Pulse 3b (capacitive coupling). Its 600 W rating, fast response (<1.0 ps), and bidirectional clamping make it suitable for 12 V and 24 V automotive sub-systems including infotainment, body control modules, and ADAS camera power rails.
How does P6SMB82C compare to P6SMB82A in terms of breakdown voltage tolerance?
P6SMB82C has a breakdown voltage range of 73.8 V to 90.2 V (±10% around nominal 82 V), while P6SMB82A tightens this to 77.9 V to 86.1 V (±5%). The 'A' suffix indicates tighter VBR tolerance, useful where precise trigger threshold matters - but P6SMB82C remains preferred when cost, availability, and bidirectional capability outweigh narrow VBR spread requirements.
What is the moisture sensitivity level (MSL) and reflow profile compatibility for P6SMB82C?
P6SMB82C is rated MSL Level 1 per J-STD-020, meaning it can be stored indefinitely at ambient conditions and withstand standard lead-free reflow profiles (peak temperature up to 260 °C) without baking. Its matte tin-plated leads comply with J-STD-002 for solderability, supporting high-yield automated placement and reflow in high-volume manufacturing of power supplies and industrial controls.
