Product details
Overview
TPSMP10HM3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for high-reliability overvoltage protection of sensitive electronics. It features 10 V breakdown voltage (VBR min/max: 9.0–11.0 V), 20.0 A peak pulse current (IPPM), 15.0 V clamping voltage (VC) at IPPM, and 185 °C maximum junction temperature - enabling robust surge protection in automotive power rails and industrial sensor interfaces.
For engineers reviewing the TPSMP10HM3/84A datasheet, TPSMP10HM3/84A pinout, TPSMP10HM3/84A application, or TPSMP10HM3/84A equivalent, key selection criteria include its AEC-Q101 qualification, 2.5 W steady-state power dissipation, low-profile 1.0 mm height, MSL Level 1 moisture sensitivity, and uni-directional polarity with cathode band marking - all critical for automotive-grade PCB layout and automated SMT assembly.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology to deliver fast response time (<1 ns) and low incremental surge resistance, ensuring effective suppression of ESD and lightning-induced transients per IEC 61000-4-2/4-5. Its junction design supports continuous operation up to +185 °C, meeting stringent thermal requirements in engine control units and under-hood electronics.
The device operates as a clamping-type protector: when reverse voltage exceeds VWM = 8.10 V, it transitions from high-impedance blocking to low-impedance conduction, limiting downstream voltage to ≤15.0 V at 20.0 A surge. Its DO-220AA package enables high power density (300 W peak pulse power for this VBR group) in minimal board area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 9.0 V / 11.0 V - defines precise voltage threshold at which clamping initiates under 1 mA test current |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ10A | DO-214AC package; 10.0 V VBR; 24.4 V VC @ 14.3 A; lower IPPM (14.3 A vs. 20.0 A) | Lower surge rating limits use in high-energy automotive transients | Select when cost-sensitive designs accept reduced surge margin and larger footprint |
| TPSMA6.8A | DO-214AC package; 6.8 V VBR; 11.2 V VC @ 27.7 A; higher IPPM but lower VBR | Not suitable for 12 V systems requiring ≥8.1 V VWM hold-off | Choose only for 5 V rail protection where tighter clamping voltage is prioritized |
Compared with SMAJ10A and TPSMA6.8A, the TPSMP10HM3/84A delivers superior power density (300 W peak in DO-220AA vs. 400 W in larger DO-214AC), AEC-Q101 qualification out-of-box, and 1.0 mm height - making it optimal for space-constrained, thermally demanding automotive modules where both reliability and miniaturization are mandatory.

FAQ
What is the breakdown voltage range of the TPSMP10HM3/84A?
The TPSMP10HM3/84A has a specified breakdown voltage (VBR) range of 9.0 V minimum to 11.0 V maximum, measured at 1.0 mA test current. This ensures consistent clamping initiation across manufacturing lots and temperature extremes, supporting reliable overvoltage protection in 12 V automotive systems where nominal rail voltage can vary between 9 V and 16 V.
Is the TPSMP10HM3/84A suitable for automotive applications?
Yes, the TPSMP10HM3/84A is AEC-Q101 qualified and rated for operation up to +185 °C junction temperature, making it suitable for under-hood and powertrain applications. Its DO-220AA package meets MSL Level 1, and its construction uses halogen-free, RoHS-compliant materials - all verified per Vishay's automotive qualification protocol for the TPSMP family.
What is the clamping voltage of the TPSMP10HM3/84A at its rated surge current?
The TPSMP10HM3/84A clamps to a maximum of 15.0 V at its rated peak pulse current (IPPM) of 20.0 A under the standard 10/1000 μs waveform. This value is guaranteed across temperature and ensures protected ICs with 16 V absolute maximum ratings remain within safe operating limits during transient events.
Does the TPSMP10HM3/84A have polarity marking, and how is it identified?
Yes, the TPSMP10HM3/84A features a visible cathode band on the DO-220AA package body. This marking aligns with industry-standard diode polarity convention: the banded end is the cathode, which must be connected toward the protected line, while the anode connects to ground or the return path in uni-directional TVS configurations.
What packaging format is supplied for the TPSMP10HM3/84A?
The TPSMP10HM3/84A is supplied in 7-inch diameter plastic tape and reel format, with a base quantity of 3000 units per reel (package code 84A). This format supports high-speed automated pick-and-place assembly and complies with EIA-481 standards for SMT manufacturing.
