Product details
Overview
P6SMB160AHM3_B/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 160 V standoff voltage (VWM), 168 V minimum breakdown voltage (VBR), and 600 W peak pulse power (10/1000 μs). It provides robust ESD and surge protection for power rails and signal lines in automotive-grade industrial electronics.
For engineers reviewing the P6SMB160AHM3_B/I datasheet, P6SMB160AHM3_B/I pinout, P6SMB160AHM3_B/I application, or P6SMB160AHM3_B/I equivalent, key selection criteria include clamping voltage (219 V at IPPM), AEC-Q101 qualification, halogen-free RoHS compliance, and thermal resistance (RθJA = 100 °C/W) under standard PCB pad layout.
Technical Context
This TVS diode operates as a unidirectional clamping device with cathode-band polarity marking, designed to shunt transient energy above its breakdown threshold while maintaining low leakage (<1.0 μA at 136 V) and fast response time. Its glass-passivated junction ensures stable performance across temperature extremes (–65 °C to +150 °C).
The device delivers 2.7 A peak pulse current (IPPM) at 219 V clamping voltage under 10/1000 μs waveform, with 0.108 %/°C temperature coefficient of VBR and 20 °C/W junction-to-lead thermal resistance. It meets J-STD-020 MSL Level 1 and JESD201 Class 2 whisker resistance requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ160AHE3_A/H | Same VWM/VBR/VC specs but in smaller SMA (DO-214AC) package; RθJA = 140 °C/W vs. 100 °C/W | Limited power dissipation in high-temperature ambient; not AEC-Q101 qualified | Select when board space is constrained and automotive qualification is unnecessary |
| 1.5SMC160AHE3_A/H | Higher PPPM (1500 W), larger SMC (DO-214AB) package; VWM = 136 V, VC = 259 V at 6.1 A | Greater surge margin but higher clamping voltage reduces protection margin for 16 V logic rails | Choose when system requires higher single-event surge immunity and can tolerate elevated clamping |
Compared with P6SMB160AHM3_B/I, SMAJ160AHE3_A/H offers footprint reduction at the cost of thermal performance and automotive validation, while 1.5SMC160AHE3_A/H trades compactness for higher surge capacity and looser voltage control-making P6SMB160AHM3_B/I optimal for space-constrained, thermally demanding AEC-Q101 applications.

FAQ
What is the clamping voltage of the P6SMB160AHM3_B/I under maximum surge conditions?
The P6SMB160AHM3_B/I exhibits a maximum clamping voltage (VC) of 219 V when subjected to its rated peak pulse current (IPPM = 2.7 A) using the standard 10/1000 μs waveform. This value is measured at TA = 25 °C on 0.2" × 0.2" copper pads and defines the upper voltage limit imposed on protected circuitry during transient events. The P6SMB160AHM3_B/I maintains this clamping performance across its full operating temperature range.
Is the P6SMB160AHM3_B/I suitable for automotive applications?
Yes, the P6SMB160AHM3_B/I is AEC-Q101 qualified, as indicated by the HM3 suffix and "_B" revision code per Vishay's ordering matrix. It has passed stress tests including high-temperature operating life, temperature cycling, and ESD per AEC-Q101 Rev D. The P6SMB160AHM3_B/I is intended for use in automotive body electronics, infotainment power supplies, and ADAS sensor interfaces where reliability under harsh environmental conditions is critical.
How does the P6SMB160AHM3_B/I differ from bidirectional variants like P6SMB160CA?
The P6SMB160AHM3_B/I is unidirectional, featuring a cathode band for polarity-sensitive placement and conducting only in reverse breakdown-ideal for DC rail protection. In contrast, P6SMB160CA is bidirectional with no polarity marking and symmetrical clamping in both directions, suited for AC lines or differential signals. The P6SMB160AHM3_B/I has identical VWM (136 V) and VC (219 V) ratings but cannot replace bidirectional types without circuit redesign.
What is the thermal resistance of the P6SMB160AHM3_B/I, and how does it affect PCB layout?
The P6SMB160AHM3_B/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the datasheet. To maintain TJ ≤ 150 °C under 5.0 W steady-state dissipation, designers must ensure adequate copper area and avoid excessive trace length. The P6SMB160AHM3_B/I benefits from thermal vias and internal ground planes to reduce effective RθJA in production layouts.
Does the P6SMB160AHM3_B/I require derating at elevated ambient temperatures?
Yes, the P6SMB160AHM3_B/I must be derated above TA = 25 °C, following the curve in Figure 2 of the datasheet. At 85 °C ambient, its peak pulse power capability drops to approximately 420 W (70% of 600 W), and its steady-state power dissipation falls to ~2.8 W. Derating ensures junction temperature remains within the 150 °C absolute maximum. The P6SMB160AHM3_B/I datasheet provides precise derating multipliers for both pulse and DC conditions.
