Product details
Overview
P6SMB110H from Taiwan Semiconductor is a unidirectional 600W surface-mount transient voltage suppressor (TVS) diode in DO-214AA (SMB) package, with a breakdown voltage range of 99–121 V, clamping voltage of 158 V at 3.9 A peak pulse current, and stand-off voltage of 89.2 V. It protects automotive and industrial power rails against ISO 7637-2 Pulse 1/2a/2b/3a/3b transients.
For engineers reviewing the P6SMB110H datasheet, P6SMB110H pinout, P6SMB110H application, or P6SMB110H equivalent, this device is selected for high-energy surge suppression in 24V/48V DC systems where low leakage (<1 µA), fast response (<1 ps), and AEC-Q101 qualification are required.
Technical Context
The P6SMB110H operates as a unidirectional avalanche diode, triggered when reverse voltage exceeds its minimum breakdown voltage (99 V). Its glass-passivated junction ensures stable VBR tolerance and low leakage (<1 µA at 89.2 V), while its thermal resistance (RθJA = 55 °C/W) supports operation up to 150 °C junction temperature.
Designed for 10/1000 µs waveform surges, it delivers 600 W non-repetitive peak pulse power with a clamping ratio (VC/VBR(min)) of ~1.59 and temperature coefficient of 0.107 %/°C - enabling predictable voltage limiting across automotive temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |

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, 110 V standoff, but bidirectional configuration; VC = 177 V @ 3.4 A | Required where AC-coupled or dual-polarity transients (e.g., RS-485 lines) must be suppressed | Select P6SMB110H for unidirectional DC rails; choose SMBJ110A only if bipolar protection is explicitly needed |
| 1.5SMC110A | Larger DO-214AB (SMC) package; same 110 V rating but higher PPPSM = 1500 W and VC = 177 V @ 8.5 A | Suitable for higher-energy environments (e.g., heavy-duty vehicle alternator regulation) where PCB space allows larger footprint | P6SMB110H offers tighter board integration; 1.5SMC110A used when surge energy exceeds 600 W capability |
Compared with SMBJ110A and 1.5SMC110A, the P6SMB110H provides optimal balance of compact SMB packaging, AEC-Q101 qualification, and precise 89.2 V standoff for 24V/48V automotive and industrial DC systems - without over-specifying size or cost.

FAQ
What is the polarity configuration of the P6SMB110H?
The P6SMB110H is a unidirectional TVS diode, with cathode marked by a band on the DO-214AA package. It conducts only during reverse overvoltage events on the cathode-connected rail, blocking forward current like a standard diode. This configuration is ideal for DC power line protection where polarity is fixed, unlike bidirectional variants such as P6SMB110AH.
Does the P6SMB110H meet automotive qualification standards?
Yes, the P6SMB110H is AEC-Q101 qualified, meaning it has passed stress tests for temperature cycling, humidity bias, mechanical shock, and high-temperature operating life required for automotive electronic components. This certification confirms its suitability for under-hood and chassis-mounted applications including engine control, body electronics, and ADAS power supplies.
What is the maximum clamping voltage of the P6SMB110H during a surge event?
The P6SMB110H has a maximum clamping voltage (VC) of 158 V at 3.9 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value represents the highest voltage seen across the device during worst-case surge conditions and is critical for ensuring downstream ICs remain within their absolute maximum ratings.
How does the P6SMB110H compare to the P6SMB110AH variant?
The P6SMB110AH is the "A" version with tighter breakdown voltage tolerance (105–116 V vs. 99–121 V for P6SMB110H) and slightly higher VWM (94.0 V vs. 89.2 V). Both share identical package, power rating, and AEC-Q101 qualification. The P6SMB110H offers broader VBR spread for cost-sensitive designs; P6SMB110AH suits applications demanding tighter voltage control.
Can the P6SMB110H be used in bidirectional signal line protection?
No - the P6SMB110H is unidirectional and unsuitable for AC or bidirectional signal lines (e.g., CAN, RS-485). For such applications, use the bidirectional P6SMB110AH or dedicated bidirectional TVS like SMBJ110A. Using P6SMB110H on a bidirectional line would result in forward conduction during half-cycles, causing malfunction or damage.
