Product details
Overview
TPSMB30-10HE3_A/I from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for clamping inductive switching surges and lightning-induced transients on power rails and signal lines. It features a 30 V breakdown voltage (VBR = 28.5–31.5 V), 25.6 V stand-off voltage (VWM), 41.4 V maximum clamping voltage at 14.5 A peak pulse current, 600 W peak pulse power (10/1000 µs), and operates up to +185 °C junction temperature - deployed in automotive power supply protection and industrial sensor interface circuits.
For engineers reviewing the TPSMB30-10HE3_A/I datasheet, TPSMB30-10HE3_A/I pinout, TPSMB30-10HE3_A/I application, or TPSMB30-10HE3_A/I equivalent, this page delivers verified electrical specs, SMB (DO-214AA) package mapping, cathode/anode terminal roles, AEC-Q101 qualification status, and direct alternative part comparisons for robust overvoltage protection design-in.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with optimized junction passivation for stable clamping under high-temperature stress. Its unidirectional polarity enables forward-biased surge conduction only during reverse overvoltage events, and its 185 °C maximum junction temperature supports operation in under-hood automotive environments without derating loss.
The device delivers 41.4 V clamping voltage at 14.5 A (10/1000 µs waveform), with low incremental surge resistance and sub-nanosecond response time. It meets MSL Level 1 per J-STD-020 and passes JESD 201 Class 2 whisker testing - confirming suitability for lead-free reflow assembly and long-term reliability in harsh thermal cycling conditions.
Key Specifications

Use Value: 185 °C TJ rating allows uninterrupted operation during sustained 70 °C ambient + self-heating conditions typical in dense telecom chassis. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30A | Same VBR range (28.5–31.5 V), but lower PPPM = 400 W; SMB package identical; not AEC-Q101 qualified | Limited to non-automotive industrial or consumer use where surge repetition rate is low | Select SMAJ30A only if AEC-Q101 qualification and 600 W capability are not required; verify thermal margin at 14.5 A IPPM |
| SMCJ30A | Higher PPPM = 1500 W; larger SMC (DO-214AB) package; same VBR, VC, and AEC-Q101 qualification | Used where higher single-pulse energy absorption is needed, e.g., front-end power entry or battery disconnect circuits | Choose SMCJ30A when board space permits larger footprint and system-level surge tests exceed 600 W requirements |
Compared with SMAJ30A and SMCJ30A, the TPSMB30-10HE3_A/I uniquely balances AEC-Q101 qualification, 600 W surge capacity, and compact SMB footprint - making it optimal for space-constrained automotive modules requiring validated reliability without over-engineering.

FAQ
What is the exact breakdown voltage range for TPSMB30-10HE3_A/I?
The TPSMB30-10HE3_A/I has a guaranteed breakdown voltage (VBR) range of 28.5 V to 31.5 V at 1 mA test current, with a nominal value of 30.0 V. This specification is measured per ANSI/IEEE C62.35 and confirmed in the Vishay datasheet revision 23-Jan-2024, Document Number 88406. The TPSMB30-10HE3_A/I maintains this tolerance across its full operating temperature range.
Is TPSMB30-10HE3_A/I AEC-Q101 qualified?
Yes, TPSMB30-10HE3_A/I is AEC-Q101 qualified. The HE3 suffix explicitly denotes RoHS-compliant and AEC-Q101 qualified construction, as stated in the Vishay ordering information and mechanical data sections. This qualification covers stress tests including HTGB, HTRB, temperature cycling, and ESD, validating its use in automotive powertrain and body electronics systems.
What does the "_A/I" suffix mean in TPSMB30-10HE3_A/I?
The "_A/I" suffix in TPSMB30-10HE3_A/I indicates two attributes: "A" is the revision code denoting the current manufacturing revision per Vishay's documentation, and "I" specifies the packaging format - 13-inch diameter plastic tape and reel with 3200 units per reel. This matches the preferred package code "I" listed in the official ordering table for TPSMB30AHE3_A/I.
Can TPSMB30-10HE3_A/I replace SMAJ30A in existing designs?
TPSMB30-10HE3_A/I is not a direct drop-in replacement for SMAJ30A due to differences in qualification and surge rating - though both share the SMB package and similar VBR. The TPSMB30-10HE3_A/I offers AEC-Q101 qualification and 600 W PPPM versus SMAJ30A's 400 W and no automotive qualification. Layout compatibility exists, but system-level validation is required for automotive use cases.
What is the maximum clamping voltage of TPSMB30-10HE3_A/I at rated surge current?
The maximum clamping voltage (VC) of TPSMB30-10HE3_A/I is 41.4 V at 14.5 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is specified in the Electrical Characteristics table of the Vishay datasheet and reflects worst-case clamping performance across process and temperature extremes - critical for ensuring protected ICs remain within absolute maximum ratings.
