Product details
Overview
P6SMB540AHE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for high-energy surge protection in power rails and signal lines. It features a 540 V breakdown voltage (VBR = 513–567 V at IT = 1.0 mA), 740 V maximum clamping voltage (VC) at 0.81 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform - deployed in automotive power supply inputs and industrial DC bus protection.
For engineers reviewing the P6SMB540AHE3_A/I datasheet, P6SMB540AHE3_A/I pinout, P6SMB540AHE3_A/I application, or P6SMB540AHE3_A/I equivalent, this part delivers AEC-Q101 qualification, SMB (DO-214AA) package compatibility, low incremental surge resistance, and verified clamping performance under repetitive transients - critical for robust overvoltage design in high-reliability 48 V–400 V systems.
Technical Context
The P6SMB540AHE3_A/I operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology to achieve fast response time (<1 ns) and stable breakdown characteristics across -65 °C to +150 °C junction temperature range. Its thermal resistance (RθJA = 100 °C/W) and RθJL = 20 °C/W support reliable operation on standard 0.2" × 0.2" copper pads without forced cooling.
Designed for transient suppression per IEC 61000-4-5 (surge) and ISO 7637-2 (automotive), it sustains 100 A non-repetitive forward surge current (IFSM) and exhibits <1.0 μA reverse leakage at 459 V stand-off voltage (VWM). The cathode-band polarity marking enables unambiguous PCB orientation during automated placement.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 513–567 V at 1.0 mA test current - defines precise avalanche initiation threshold for predictable clamping onset |
| Stand-off Voltage VWM | 459 V maximum - ensures no conduction during normal 400 V DC bus operation with 10 % margin |
| Clamping Voltage VC | 740 V at 0.81 A IPPM - limits downstream voltage stress during 600 W transient events |
| Peak Pulse Power PPPM | 600 W with 10/1000 μs waveform - handles high-energy surges common in automotive load-dump and inductive switching |
| Operating Temperature | -65 °C to +150 °C - supports under-hood and industrial ambient conditions without derating |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |

Use Scenario: Protecting primary-side MOSFETs and controllers in 12 V → 48 V bidirectional DC-DC converters subjected to load-dump transients up to ±120 V. IC Role / Device Role / Timing Role: Unidirectional TVS placed between HV rail and chassis ground to clamp positive overvoltage spikes before they reach gate drivers or PWM controllers. Use Value: Limits transient voltage to ≤740 V, preserving 800 V-rated SiC MOSFETs and enabling use of lower-cost isolation components. |
Use Scenario: Safeguarding PLC power modules and servo drives operating from rectified 3-phase 380 V AC, exposed to lightning-induced surges on long cable runs. IC Role / Device Role / Timing Role: Standoff-rated TVS mounted directly at DC bus input terminals to absorb energy from IEC 61000-4-5 Level 4 (4 kV) surges. Use Value: Delivers 600 W clamping capacity with <1 ns response, preventing latch-up or destruction of upstream rectifiers and bulk capacitors. |
| Telecom Remote Radio Unit (RRU) Power Supply | EV Onboard Charger (OBC) Auxiliary Rail |
|
Use Scenario: Securing 48 V backup power inputs in outdoor base station RRUs where induced surges from nearby lightning strikes exceed 1 kV. IC Role / Device Role / Timing Role: Primary-line TVS on 48 V input stage, coordinated with MOVs and filters to meet GR-1089-CORE immunity requirements. Use Value: Maintains <1 μA leakage at 459 V VWM, minimizing standby power loss while providing repeatable 740 V clamping under multi-pulse stress. |
Use Scenario: Protecting 12 V auxiliary control rail in EV OBCs powered from vehicle battery, subject to jump-start transients and alternator load dump. IC Role / Device Role / Timing Role: Unidirectional suppressor tied between 12 V rail and ground, activated only during positive overvoltage events above 459 V. Use Value: AEC-Q101 qualification ensures compliance with ISO 16750-2, eliminating need for secondary qualification testing in automotive production. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ540A | Same VBR range (513–567 V) but 400 W PPPM rating; SMA package (smaller footprint, higher RθJA = 140 °C/W) | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a without parallel devices | Select when board space is constrained and surge energy is ≤400 W; verify thermal margin at 100 °C ambient |
| SMCJ540A | Same VBR and 1500 W PPPM rating; larger SMC (DO-214AB) package with RθJA = 50 °C/W | Overqualified for 600 W needs; adds 30 % board area and cost without functional benefit | Choose only if system-level testing reveals marginal clamping margin with P6SMB540AHE3_A/I or future derating headroom is required |
Compared with SMAJ540A and SMCJ540A, the P6SMB540AHE3_A/I delivers optimal balance of 600 W surge handling, AEC-Q101 compliance, SMB footprint, and thermal performance - making it the preferred choice for space-constrained automotive and industrial 400 V+ protection where both reliability and layout efficiency matter.

FAQ
What is the maximum clamping voltage of the P6SMB540AHE3_A/I under peak pulse conditions?
The P6SMB540AHE3_A/I has a maximum clamping voltage (VC) of 740 V when subjected to its rated peak pulse current of 0.81 A with a 10/1000 μs waveform. This value is measured per standard test conditions (TA = 25 °C, mounted on 0.2" × 0.2" copper pads) and defines the upper voltage limit imposed on protected circuits during transient events. The P6SMB540AHE3_A/I maintains this clamping performance consistently due to its glass-passivated junction and low incremental surge resistance.
Is the P6SMB540AHE3_A/I qualified for automotive applications?
Yes, the P6SMB540AHE3_A/I carries the HE3 suffix, indicating full AEC-Q101 qualification for automotive use. It has passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and ESD per JESD22 standards. This makes the P6SMB540AHE3_A/I suitable for under-hood and chassis-mounted applications such as DC-DC converter inputs and battery management system protection where zero-field-failure reliability is required.
What does the "A" in P6SMB540AHE3_A/I signify?
The "A" in P6SMB540AHE3_A/I denotes unidirectional polarity - meaning the device functions as a single-ended avalanche diode that clamps only positive transients relative to ground. The cathode band identifies the terminal connected to the line being protected, while the anode connects to ground. This distinguishes it from bidirectional variants (e.g., P6SMB540CA), which suppress both polarities and carry the "CA" suffix instead.
What is the standoff voltage rating of the P6SMB540AHE3_A/I?
The P6SMB540AHE3_A/I has a maximum reverse stand-off voltage (VWM) of 459 V, ensuring no significant conduction occurs during normal operation up to that voltage. This provides a 10 % margin below its minimum breakdown voltage (513 V), allowing safe operation on 400 V DC systems while retaining robust transient headroom. Reverse leakage remains below 1.0 μA at VWM, minimizing standby power impact in always-on applications.
Which package type does the P6SMB540AHE3_A/I use, and what are its key mechanical features?
The P6SMB540AHE3_A/I uses the SMB (DO-214AA) surface-mount package: 5.59 mm × 4.06 mm body size with 2.20 mm maximum height, UL 94 V-0 rated molding compound, and matte tin-plated leads compliant with J-STD-002 solderability and JESD22-B102 whisker testing. Its low-profile design supports automated placement and reflow up to 260 °C peak, and the cathode band provides clear polarity identification for error-free assembly.
