Product details
Overview
P6SMB250A01HM3_A/I from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 250 V standoff voltage (VWM), 237–263 V breakdown voltage (VBR) at 1 mA, and 344 V maximum clamping voltage (VC) under 1.74 A peak pulse current (IPPM) with 10/1000 μs waveform. It delivers 600 W peak pulse power for protecting power rails and signal lines in automotive and industrial systems against ESD and inductive switching transients.
For engineers reviewing the P6SMB250A01HM3_A/I datasheet, P6SMB250A01HM3_A/I pinout, P6SMB250A01HM3_A/I application, or P6SMB250A01HM3_A/I equivalent, this part is selected for high-voltage DC bus protection where clamping voltage margin, AEC-Q101 qualification, and halogen-free RoHS compliance are required - especially in 24 V/48 V commercial vehicle electronics and industrial motor drives.
Technical Context
The P6SMB250A01HM3_A/I operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology to achieve fast response (<1 ns) and low incremental surge resistance. Its clamping behavior is defined by a 10/1000 μs double-exponential pulse, with thermal derating per Fig. 2 above TA = 25 °C and RθJA = 100 °C/W.
Designed for automated SMT placement on 0.2" × 0.2" copper pads, it meets JESD201 Class 2 whisker resistance and MSL Level 1 (260 °C peak reflow). The HM3 suffix confirms halogen-free, RoHS-compliant construction and AEC-Q101 qualification per revision D for high-reliability automotive use.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ250A-E3/5B | Same VWM/VBR/VC specs but non-AEC-Q101, standard RoHS (E3), MSL Level 1, SMB package. | Lacks automotive qualification; suitable for industrial/commercial designs without AEC-Q101 mandate. | Select when cost sensitivity outweighs automotive reliability requirements and lifecycle traceability is not mandated. |
| 1.5SMC250AHE3_A | Higher package thermal resistance (RθJA = 125 °C/W vs. 100 °C/W), same electrical specs, SMC (DO-214AB) package (larger footprint). | Requires larger PCB area; less suitable for space-constrained automotive modules. | Choose only if existing SMC footprint is fixed and thermal margin allows higher junction rise under repeated surges. |
Compared with SMAJ250A-E3/5B and 1.5SMC250AHE3_A, the P6SMB250A01HM3_A/I uniquely combines AEC-Q101 qualification, halogen-free construction, and optimized SMB thermal performance - making it the preferred choice for new automotive designs requiring both compliance and compact layout.

FAQ
What is the maximum clamping voltage of the P6SMB250A01HM3_A/I under standard test conditions?
The P6SMB250A01HM3_A/I has a maximum clamping voltage (VC) of 344 V when subjected to a 10/1000 μs waveform at a peak pulse current (IPPM) of 1.74 A. This value is measured at TA = 25 °C with the device mounted on 0.2" × 0.2" copper pads per the datasheet's recommended layout. The clamping voltage directly determines the overvoltage stress imposed on downstream components during transient events, and the P6SMB250A01HM3_A/I maintains this specification across its qualified temperature range.
Is the P6SMB250A01HM3_A/I AEC-Q101 qualified, and what does the "HM3" suffix indicate?
Yes, the P6SMB250A01HM3_A/I is AEC-Q101 qualified - specifically under the "D" revision for high-voltage variants (250 V to 540 V), as confirmed in the Vishay ordering information table. The "HM3" suffix denotes halogen-free, RoHS-compliant construction with AEC-Q101 qualification, distinguishing it from commercial-grade "E3" or "M3" variants. This makes the P6SMB250A01HM3_A/I suitable for automotive applications requiring validated reliability and environmental compliance.
How does the thermal resistance of the P6SMB250A01HM3_A/I affect its surge handling capability?
The P6SMB250A01HM3_A/I has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted per the recommended 0.2" × 0.2" copper pad layout. This value directly impacts sustained surge capability: at elevated ambient temperatures, the junction temperature rise must stay below 150 °C. For example, at TA = 85 °C and 5 W steady-state dissipation, TJ reaches 135 °C - leaving only 15 °C margin before derating begins. Thus, the P6SMB250A01HM3_A/I's RθJA enables reliable 600 W pulse handling in thermally constrained automotive modules.
Can the P6SMB250A01HM3_A/I be used in bidirectional configurations?
No, the P6SMB250A01HM3_A/I is a unidirectional TVS diode, indicated by the "A" suffix and cathode band marking. Bidirectional variants in the P6SMB family use the "CA" suffix (e.g., P6SMB250CA). Using the P6SMB250A01HM3_A/I in reverse-biased AC applications would result in forward conduction and potential failure. For bidirectional protection at 250 V, engineers must select a verified CA-series part - the P6SMB250A01HM3_A/I is strictly for DC rail clamping with defined polarity.
What is the reverse leakage current of the P6SMB250A01HM3_A/I at its maximum standoff voltage?
At its maximum standoff voltage (VWM) of 214 V and TA = 25 °C, the P6SMB250A01HM3_A/I exhibits a maximum reverse leakage current (ID) of 1.0 μA. This ultra-low leakage ensures minimal power loss in always-on systems such as automotive body control modules or industrial sensors, where standby current budgets are tight. The value remains within specification across the full operating temperature range (-65 °C to +150 °C), supporting reliable long-term deployment without cumulative leakage drift.
