Product details
Overview
P6SMB110A from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode with a 105–116 V breakdown voltage (VBR), 94.0 V stand-off voltage (VWM), and 152 V maximum clamping voltage (VC) at 4.1 A peak pulse current. It provides robust ESD and surge protection for DC power rails in switching mode power supplies, adapters, and display electronics.
For engineers reviewing the P6SMB110A datasheet, P6SMB110A pinout, P6SMB110A application, or P6SMB110A equivalent, key selection criteria include its DO-214AA (SMB) package compatibility, 1.0 mA test current specification, <1 µA reverse leakage at VWM, ISO 7637-2 Pulse 1/2a/2b/3a/3b compliance, and thermal resistance of 55 °C/W (RθJA).
Technical Context
The P6SMB110A operates as a unidirectional avalanche diode, designed to clamp transient overvoltages above its VWM (94.0 V) while maintaining low leakage (<1 µA) under normal operation. Its 152 V clamping voltage at 4.1 A ensures downstream circuit protection during 10/1000 µs surges.
It features glass-passivated junction construction, meets JESD201 Class 2 whisker resistance, and is rated for -55 °C to +150 °C junction temperature. Thermal performance includes RθJC = 10 °C/W and RθJA = 55 °C/W, supporting reliable operation in compact, thermally constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 105 V / 116 V - defines guaranteed avalanche conduction onset range at 1.0 mA test current |
| VWM | 94.0 V - maximum continuous reverse operating voltage before significant leakage begins |
| VC @ IPPM | 152 V at 4.1 A - clamped voltage during 10/1000 µs surge, limiting stress on protected ICs |
| PPPSM | 600 W - non-repetitive peak pulse power handling per standard 10/1000 µs waveform |
| IR @ VWM | <1 µA - ultra-low reverse leakage preserves efficiency in high-impedance bias networks |
| TJ max | +150 °C - enables use in high-temperature industrial and automotive under-hood environments |
| RθJA | 55 °C/W - quantifies thermal resistance from junction to ambient, critical for power derating |
Pinout & Package
Package: DO-214AA (SMB), surface-mount, single-diode configuration with cathode band marking. Matte tin-plated leads, RoHS-compliant and halogen-free per IEC 61249-2-21.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / Surge return path | Connected to system ground or low-side reference; completes clamping loop during transients |
| Cathode | Protected line connection | Connected to the rail being protected (e.g., +12 V, +24 V, or +48 V DC bus); conducts when VKA exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity stress |
| Fast response time <1.0 ps | Enables clamping before sensitive downstream components experience overvoltage damage |
| ISO 7637-2 compliance (Pulse 1/2a/2b/3a/3b) | Validates suitability for automotive 12 V/24 V power network surge immunity requirements |
| Moisture sensitivity level 1 | Eliminates need for baking prior to reflow, simplifying SMT assembly and reducing process risk |
| UL 94V-0 molding compound | Meets flammability safety standards for enclosed power electronics and consumer displays |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ110A | Same DO-214AA package, identical VBR (105–116 V), but rated for 600 W with slightly higher VC (156 V) | Designed for broader industrial temperature range (-65 °C to +150 °C) vs. P6SMB110A (-55 °C to +150 °C) | Prefer SMBJ110A where extended low-temperature operation or alternate qualification history is required |
| 1.5SMC110A | Higher power rating (1500 W), larger DO-214AB (SMC) package, same VBR range and VC (152 V) | Used where higher single-pulse energy absorption is needed, e.g., in telecom power interfaces or railway systems | Select 1.5SMC110A only if board space allows SMC footprint and 1500 W surge margin is mandatory |
Compared with SMBJ110A and 1.5SMC110A, the P6SMB110A offers optimal balance of 600 W surge capability, SMB footprint density, and cost-efficiency for consumer and industrial SMPS applications-without requiring layout changes or thermal redesign.

FAQ
What is the maximum clamping voltage of the P6SMB110A under standard surge conditions?
The P6SMB110A has a maximum clamping voltage (VC) of 152 V when subjected to its rated 4.1 A peak pulse current (IPPM) using the standard 10/1000 µs waveform. This value is measured at TA = 25 °C and ensures predictable overvoltage limiting for downstream components in the protected circuit.
Is the P6SMB110A suitable for automotive applications?
Yes-the P6SMB110A meets ISO 7637-2 Pulse 1, 2a, 2b, 3a, and 3b test requirements, making it suitable for 12 V and 24 V automotive power network protection. Its -55 °C to +150 °C operating junction temperature range and glass-passivated junction support under-hood and infotainment module deployment.
Does the P6SMB110A have bidirectional capability?
No-the P6SMB110A is a unidirectional TVS diode, intended for DC rail protection with defined anode-cathode polarity. For bidirectional AC or data-line protection, the P6SMB110CA variant (with CA suffix) must be used instead.
What is the reverse leakage current of the P6SMB110A at its rated stand-off voltage?
At its VWM of 94.0 V and TA = 25 °C, the P6SMB110A exhibits a maximum reverse leakage current (IR) of 1 µA. This ultra-low leakage minimizes standby power loss and avoids false triggering in high-impedance sensing or control circuits.
What packaging and reel quantity is offered for the P6SMB110A?
The P6SMB110A is supplied in DO-214AA (SMB) package format on tape-and-reel, with 3,000 units per reel. This configuration supports automated SMT placement and is compatible with standard 8 mm carrier tape equipment used in high-volume manufacturing.
