Product details
Overview
TPSMA7.5HE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, rated for 7.5 V breakdown voltage (VBR), 400 W peak pulse power (10/1000 µs), and 185 °C maximum junction temperature. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients and lightning surges in automotive and industrial systems.
For engineers reviewing the TPSMA7.5HE3_A/H datasheet, TPSMA7.5HE3_A/H pinout, TPSMA7.5HE3_A/H application, or TPSMA7.5HE3_A/H equivalent, key selection criteria include clamping voltage (35.4 V at 11.3 A), stand-off voltage (6.40 V), unidirectional polarity, AEC-Q101 qualification, and RoHS-compliant HE3 suffix with MSL Level 1 rating.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable clamping under repetitive surge conditions. Its 185 °C junction rating enables operation in high-temperature automotive engine compartments and industrial motor drives without derating penalties.
The device exhibits low incremental surge resistance and fast response time-critical for protecting sensitive gate drivers and data lines. Clamping performance is specified at 11.3 A peak pulse current (IPPM) with 35.4 V maximum clamping voltage (VC), ensuring robust overvoltage suppression within tight system margins.

Applications
| Automotive Power Distribution | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load-dump and alternator ripple transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp positive spikes above 13.5 V. Use Value: Withstands 40 A IFSM and maintains 6.40 V stand-off to avoid false triggering during normal operation. | Use Scenario: Shielding analog output lines of pressure/temperature sensors in factory automation PLCs. IC Role / Device Role / Timing Role: TVS connected across signal and ground to suppress ESD and inductive kickback from nearby solenoids. Use Value: 35.4 V clamping voltage ensures ADC input stays within ±10 V absolute maximum rating during 1 kV/500 A surge events. |
| Consumer Power Adapter Input Stage | Telecom Line Card Surge Protection |
Use Scenario: Front-end protection on AC/DC adapter primary-side rectifier outputs. IC Role / Device Role / Timing Role: Unidirectional TVS absorbing flyback energy from transformer leakage inductance during MOSFET turn-off. Use Value: 400 W PPPM and 185 °C TJ allow sustained operation in compact, thermally constrained enclosures. | Use Scenario: Secondary-side protection on Ethernet PHY power rails exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Standoff-rated TVS on +3.3 V supply to prevent latch-up in Gigabit PHY ICs during telecom-grade surge testing. Use Value: 150 µA max reverse leakage at VWM avoids loading low-current bias networks in always-on network equipment. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ7.0A | Lower VBR (6.65–7.37 V), same SMA package, 600 W PPPM, but only 150 °C TJ max | Not AEC-Q101 qualified; suitable for commercial-grade consumer electronics only | Select when higher pulse power is needed and automotive qualification is not required |
| TPSMA7.5AHE3_A/H | Same electrical specs and qualification, but lacks halogen-free certification (HM3 suffix variant) | Identical performance in all applications; differs only in material compliance documentation | Choose TPSMA7.5HE3_A/H for RoHS + AEC-Q101; choose HM3 version if halogen-free compliance is mandated |
Compared with SMBJ7.0A and TPSMA7.5AHE3_A/H, the TPSMA7.5HE3_A/H uniquely combines AEC-Q101 qualification, 185 °C operation, and RoHS compliance in a single SMA package-making it the preferred choice for automotive and high-reliability industrial designs where thermal margin and certification rigor are non-negotiable.

FAQ
What is the exact breakdown voltage range for TPSMA7.5HE3_A/H?
The TPSMA7.5HE3_A/H has a guaranteed breakdown voltage (VBR) range of 7.13 V (minimum) to 7.88 V (maximum) at 10 mA test current, with a nominal value of 7.50 V. This specification is measured per ANSI/IEEE C62.35 and confirmed in the official Vishay datasheet (Document Number: 88405, Rev. 23-Jan-2024). The TPSMA7.5HE3_A/H maintains this tolerance across its full operating temperature range.
Is TPSMA7.5HE3_A/H qualified for automotive applications?
Yes, the TPSMA7.5HE3_A/H is AEC-Q101 qualified, as explicitly stated in the Vishay datasheet under "FEATURES" and "ORDERING INFORMATION". The HE3 suffix denotes RoHS-compliant and AEC-Q101 qualified construction. This makes the TPSMA7.5HE3_A/H suitable for use in automotive subsystems such as body control modules, infotainment power supplies, and ADAS sensor interfaces where reliability under thermal and electrical stress is critical.
What is the maximum clamping voltage of TPSMA7.5HE3_A/H and at what current is it specified?
The TPSMA7.5HE3_A/H has a maximum clamping voltage (VC) of 35.4 V, measured at a peak pulse current (IPPM) of 11.3 A using a 10/1000 µs waveform. This value is specified in the "ELECTRICAL CHARACTERISTICS" table of the Vishay datasheet and reflects worst-case clamping performance under standardized surge conditions-ensuring protected circuits remain within safe voltage limits during transient events.
Does TPSMA7.5HE3_A/H have a bidirectional configuration?
No, the TPSMA7.5HE3_A/H is unidirectional only, as confirmed in the "FEATURES" section of the Vishay datasheet: "Available in uni-directional polarity only." Its cathode band marks the terminal that connects to the higher-potential side of the protected circuit. For bidirectional protection, engineers must select a different part number (e.g., TPSMA7.5CA series), which is not offered in the HE3 suffix variant.
What is the package type and mounting requirement for TPSMA7.5HE3_A/H?
The TPSMA7.5HE3_A/H uses the SMA (DO-214AC) surface-mount package, with dimensions defined in the "PACKAGE OUTLINE DIMENSIONS" section of the Vishay datasheet. It requires 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal for thermal performance and surge handling. The device is MSL Level 1 rated, allowing standard reflow profiles up to 260 °C peak without pre-baking.
