Product details
Overview
P6SMB170AHE3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 170 V standoff voltage (VWM), 179 V maximum breakdown voltage (VBR), and 600 W peak pulse power (10/1000 μs). It clamps transients to 234 V at 2.6 A peak pulse current and is AEC-Q101 qualified for automotive electronics protection.
For engineers reviewing the P6SMB170AHE3/52 datasheet, P6SMB170AHE3/52 pinout, P6SMB170AHE3/52 application, or P6SMB170AHE3/52 equivalent, key selection criteria include unidirectional polarity, 170 V stand-off rating, 234 V clamping voltage at rated IPPM, AEC-Q101 qualification status, and SMB package compatibility with automated SMT assembly.
Technical Context
This TVS diode operates as a unidirectional clamping device, leveraging a glass-passivated silicon junction to deliver fast response (<1 ns) and low incremental surge resistance. Its 600 W peak pulse power rating is defined per 10/1000 μs waveform with 0.01% duty cycle, and thermal performance is characterized by RθJA = 100 °C/W and RθJL = 20 °C/W.
The device features a cathode-band polarity marking, supports 100 A IFSM (8.3 ms half-sine surge), and maintains stable operation across -65 °C to +150 °C junction temperature range. 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 |
|---|---|---|---|
| SMAJ170A-E3/52 | Same VWM/VBR/VC ratings but SMA package (smaller footprint, higher RθJA = 140 °C/W) | Limited to lower average power or forced-air cooled environments due to thermal derating | Select when board space is constrained and peak pulse duty cycle remains <0.01% |
| 1.5KE170A | Through-hole DO-201 package, identical electrical specs but 1.5 kW peak power rating | Requires manual or wave soldering; unsuitable for fully automated SMT lines | Choose only for legacy through-hole designs or prototyping where rework tolerance is prioritized over density |
Compared with SMAJ170A-E3/52 and 1.5KE170A, P6SMB170AHE3/52 delivers optimal balance of AEC-Q101 qualification, SMB manufacturability, and thermal robustness (RθJL = 20 °C/W) for high-volume automotive and industrial SMT production.

FAQ
What is the clamping voltage of P6SMB170AHE3/52 at its rated peak pulse current?
The P6SMB170AHE3/52 clamps to a maximum of 234 V when subjected to its specified peak pulse current of 2.6 A under the 10/1000 μs waveform condition. This value is measured per Figure 1 in Vishay document 88370 and defines the upper voltage limit imposed on protected circuitry during transient events. The clamping performance remains consistent across the full operating temperature range of −65 °C to +150 °C.
Is P6SMB170AHE3/52 suitable for automotive applications?
Yes, P6SMB170AHE3/52 is AEC-Q101 qualified, as confirmed by the "HE3" suffix and documentation in Vishay's P6SMB series datasheet (Rev. 09-Jan-2024, Doc. #88370). It has passed stress tests including temperature cycling, high-temperature reverse bias, and ESD per AEC-Q101 requirements, making it appropriate for under-hood and cabin-mounted automotive electronics such as body control modules and sensor interfaces.
What does the "HE3" suffix indicate in P6SMB170AHE3/52?
The "HE3" suffix in P6SMB170AHE3/52 denotes RoHS-compliant construction with AEC-Q101 qualification and packaging in 7" plastic tape and reel (order code /52). It distinguishes this variant from commercial-grade E3/M3 versions and confirms compliance with automotive reliability standards, halogen-free materials, and J-STD-020 MSL Level 1 reflow compatibility.
How does P6SMB170AHE3/52 differ from bidirectional variants like P6SMB170CA?
P6SMB170AHE3/52 is unidirectional and features a cathode band for polarity-sensitive placement, whereas P6SMB170CA is bidirectional with no polarity marking and symmetric clamping in both directions. The unidirectional version offers lower leakage (<1 μA at 145 V) and is preferred for DC supply rail protection, while the bidirectional type suits AC-coupled signal lines like RS-485 or Ethernet PHY interfaces.
What is the thermal resistance from junction to ambient for P6SMB170AHE3/52?
The typical thermal resistance from junction to ambient (RθJA) for P6SMB170AHE3/52 is 100 °C/W when mounted on the minimum recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in Vishay document 88370. This value assumes still air conditions and is used to calculate steady-state temperature rise under continuous power dissipation up to 5.0 W.
