Product details
Overview
P6SMB30A-E3/52 from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a 30 V breakdown voltage (VBR = 28.5–31.5 V at 1 mA), 41.4 V maximum clamping voltage (VC) at 14.5 A peak pulse current, and 600 W peak pulse power rating with 10/1000 μs waveform - deployed to safeguard MOSFETs, ICs, and sensor interfaces against inductive switching transients and ESD in industrial and automotive electronics.
For engineers reviewing the P6SMB30A-E3/52 datasheet, P6SMB30A-E3/52 pinout, P6SMB30A-E3/52 application, or P6SMB30A-E3/52 equivalent, key selection criteria include its unidirectional polarity, SMB (DO-214AA) package compatibility, 25.6 V stand-off voltage (VWM), <1 μA reverse leakage at VWM, and AEC-Q101 qualification availability via HE3 suffix variants.
Technical Context
This TVS diode operates as a clamping device that remains non-conductive below VWM = 25.6 V and rapidly avalanches above VBR = 28.5–31.5 V to limit transient voltages. Its glass-passivated junction ensures stable breakdown characteristics and low incremental surge resistance.
Designed for automated SMT assembly, it delivers 600 W peak pulse power handling with 10/1000 μs waveform at 0.01% duty cycle, and meets MSL Level 1 per J-STD-020 with 260 °C reflow peak temperature tolerance. Thermal resistance is RθJA = 100 °C/W (typ.) on standard 0.2" × 0.2" copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage VBR | 28.5–31.5 V at 1 mA test current - defines precise avalanche initiation threshold for reliable clamping onset |
| Stand-off Voltage VWM | 25.6 V - maximum continuous reverse operating voltage before leakage exceeds 1 μA |
| Clamping Voltage VC | 41.4 V at 14.5 A IPPM - limits transient voltage seen by protected circuitry during 10/1000 μs surge |
| Peak Pulse Power PPPM | 600 W - sustains high-energy transients without failure under standardized 10/1000 μs waveform |
| Package | SMB (DO-214AA) - low-profile SMT package with 0.220" × 0.130" footprint, optimized for automated placement and thermal pad layout |
| Operating Temperature | −65 °C to +150 °C - supports deployment in under-hood automotive and industrial environments |
| RoHS Compliance | E3 suffix - RoHS-compliant, commercial-grade, matte tin-plated leads solderable per J-STD-002 |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, unidirectional configuration with cathode band marking. Dimensions: 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); recommended mounting pad: 5.59 mm × 2.13 mm per terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward bias; connected to system ground or low-side reference | Provides return path during clamping; must be routed with low-inductance trace to minimize VL overshoot |
| Cathode | Protected line connection; marked with band | Connected to line under protection (e.g., 24 V rail or sensor input); conducts avalanche current to anode during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 μs) | Enables protection against high-energy load dump and inductive kick events common in 24 V industrial systems |
| 41.4 V clamping voltage at 14.5 A | Ensures downstream 3.3 V/5 V logic and 40 V-rated MOSFETs remain within safe operating area during surge |
| Glass passivated junction | Delivers stable VBR tolerance (±5%) and long-term reliability under thermal cycling and humidity stress |
| MSL Level 1, 260 °C peak reflow | Supports single-pass lead-free reflow without popcorn effect or bond wire damage |
| Low profile SMB package | Reduces board space vs. SMA/SMB alternatives while maintaining thermal performance on 5 mm² copper pads |
Applications

| Telecom Power Supply Input | Consumer Appliance Sensor Interface |
|

IC Role / Device Role / Timing Role: Primary clamping device upstream of input filter and controller IC, absorbing energy before front-end rectifiers. Use Value: Limits peak voltage to ≤41.4 V, preventing overvoltage shutdown or damage to 60 V-rated primary-side FETs and controllers. |
Use Scenario: ESD and contact discharge protection for analog sensor outputs (e.g., thermistors, hall-effect switches) in washing machines and HVAC controls. IC Role / Device Role / Timing Role: Localized TVS mounted directly at connector or PCB edge, shunting ±8 kV HBM ESD pulses to ground. Use Value: Achieves IEC 61000-4-2 Level 4 compliance with <10 ns response time and no signal distortion on mV-level sensor signals. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30A | Same VBR range (28.5–31.5 V), but lower PPPM = 400 W and higher VC = 48.4 V at 8.3 A | Less suitable for high-energy 24 V load dump; requires derating above 85 °C ambient | Select when cost sensitivity outweighs peak surge margin and board space allows larger thermal pad |
| 1.5SMC33A | Higher VWM = 28.2 V, VC = 45.7 V at 13.1 A, same 600 W PPPM, but larger SMC (DO-214AB) package | Offers better thermal dissipation but occupies ~30% more PCB area; not drop-in compatible | Choose for extended thermal life in high-reliability 24 V power rails where layout permits larger footprint |
Compared with SMAJ30A and 1.5SMC33A, P6SMB30A-E3/52 provides optimal balance of compact SMB footprint, 600 W surge capacity, and tight 41.4 V clamping - making it preferred for space-constrained 24 V industrial modules where both size and clamping performance are critical.

FAQ
What is the breakdown voltage tolerance of P6SMB30A-E3/52?
The P6SMB30A-E3/52 has a specified breakdown voltage (VBR) range of 28.5 V to 31.5 V at 1 mA test current, representing a ±5% tolerance around the nominal 30 V rating. This tight tolerance ensures predictable clamping behavior across production lots and temperature ranges, critical for protecting voltage-sensitive loads like microcontrollers and analog sensors.
Does P6SMB30A-E3/52 meet automotive qualification standards?
The base P6SMB30A-E3/52 is RoHS-compliant and commercial-grade; however, Vishay offers AEC-Q101 qualified versions under ordering codes such as P6SMB30AHE3_B. These variants undergo stress testing per AEC-Q101 and are marked with "HE3" and revision code "B", confirming suitability for automotive under-hood and body electronics applications.
What is the maximum clamping voltage of P6SMB30A-E3/52 under surge conditions?
The P6SMB30A-E3/52 exhibits a maximum clamping voltage (VC) of 41.4 V when subjected to its rated peak pulse current of 14.5 A using the standardized 10/1000 μs waveform. This value is measured at the device terminals and defines the upper voltage limit imposed on protected circuitry during transient events.
Can P6SMB30A-E3/52 be used in bidirectional configurations?
No - P6SMB30A-E3/52 is a unidirectional TVS diode, identifiable by its cathode band marking. For bidirectional operation, Vishay specifies the P6SMB30CA variant (with "CA" suffix), which provides symmetrical clamping in both polarities and no polarity marking on the package.
What is the thermal resistance of P6SMB30A-E3/52 in standard mounting conditions?
The P6SMB30A-E3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on minimum recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes still air convection and is essential for calculating junction temperature rise under sustained power dissipation or repetitive surge conditions.
