Product details
Overview
TPSMP7.5HM3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for primary overvoltage protection of low-voltage signal lines and power rails. It features 7.5 V nominal breakdown voltage (VBR = 6.75–8.25 V), 300 W peak pulse power (10/1000 µs), 25.6 V clamping voltage at 500 A surge current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the TPSMP7.5HM3/84A datasheet, TPSMP7.5HM3/84A pinout, TPSMP7.5HM3/84A application, or TPSMP7.5HM3/84A equivalent, this device is selected for robust ESD/surge protection in space-constrained, high-reliability environments-especially where 1.0 mm profile, TJ = 185 °C operation, and MSL Level 1 solderability are critical design requirements.
Technical Context
This TVS uses passivated anisotropic rectifier technology to achieve low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD (IEC 61000-4-2) and lightning-induced transients (IEC 61000-4-5). Its unidirectional configuration supports DC-biased lines with defined polarity, requiring cathode-band orientation during PCB layout.
The device operates across -65 °C to +185 °C junction temperature range and delivers stable clamping performance under repetitive surge stress when mounted on 5.0 mm × 5.0 mm copper pads per terminal. Its 0.057 %/°C VBR temperature coefficient ensures predictable voltage threshold drift over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.75 V / 8.25 V - Ensures reliable triggering above 6.05 V stand-off voltage while avoiding false trips during normal 5.5–6.05 V system operation. |
| VC @ IPPM | 25.6 V at 500 A - Limits downstream IC voltage stress to safe levels during 10/1000 µs surges, protecting 24 V-rated components. |
| PPPM | 300 W - Sustains high-energy transients without thermal runaway when used with recommended PCB copper area. |
| IR @ VWM | 150 µA max at 6.05 V - Minimizes standby leakage in battery-powered sensor nodes and low-power microcontroller interfaces. |
| TJ max | +185 °C - Supports under-hood automotive placement and high-ambient industrial control modules without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5A | DO-214AC (SMA) package; 400 W PPPM; higher VC = 12.9 V at 32.4 A; 2.2 mm height. | Less suitable for ultra-low-profile layouts; better for higher-current, lower-clamp-voltage needs in non-automotive industrial use. | Select SMAJ7.5A only if board height > 2.0 mm is acceptable and clamping voltage < 13 V is prioritized over footprint size. |
| TPSMA6.8A | Same DO-220AA package; lower VBR = 6.45–7.14 V; 250 W PPPM; VC = 10.5 V at 500 A. | Better for 5 V systems with tighter clamping margin but reduced surge handling vs. TPSMP7.5HM3/84A's 300 W rating. | Choose TPSMA6.8A when protecting 3.3 V/5 V logic with strict <11 V clamping, accepting lower peak power capability. |
Compared with SMAJ7.5A and TPSMA6.8A, the TPSMP7.5HM3/84A uniquely balances 300 W surge capacity, 1.0 mm profile, and AEC-Q101 qualification-making it optimal for automotive and space-constrained industrial applications where both reliability and form factor are non-negotiable.

FAQ
What is the maximum clamping voltage of the TPSMP7.5HM3/84A under surge conditions?
The TPSMP7.5HM3/84A exhibits a maximum clamping voltage (VC) of 25.6 V when subjected to its rated peak pulse current of 500 A (10/1000 µs waveform). This value is measured per ANSI/IEEE C62.35 standards and ensures downstream circuitry remains within safe operating limits during transient events. The TPSMP7.5HM3/84A maintains this clamping performance across its full operating temperature range.
Is the TPSMP7.5HM3/84A suitable for automotive applications?
Yes, the TPSMP7.5HM3/84A is AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood and cabin automotive applications such as sensor protection, body control modules, and infotainment power rails. Its halogen-free, RoHS-compliant construction and MSL Level 1 rating further support automotive manufacturing requirements. The TPSMP7.5HM3/84A meets these criteria without derating.
What does the "HM3/84A" suffix indicate in TPSMP7.5HM3/84A?
The "HM3" suffix denotes halogen-free, RoHS-compliant construction with JESD 201 Class 2 whisker resistance, while "/84A" specifies the packaging format: 7-inch plastic tape and reel containing 3000 units. This ordering code aligns with Vishay's standardized delivery mode nomenclature and confirms the part is supplied in automated assembly-ready format. The TPSMP7.5HM3/84A is shipped in this exact configuration.
How does the TPSMP7.5HM3/84A compare to bidirectional TVS diodes?
The TPSMP7.5HM3/84A is unidirectional and intended for DC-biased lines where reverse conduction must be blocked-such as 5 V power rails or CAN bus signals. Unlike bidirectional variants, it provides lower leakage and sharper turn-on characteristics in forward bias but cannot protect AC-coupled or floating lines. For applications requiring symmetric surge handling, a different device type would be needed; the TPSMP7.5HM3/84A is optimized for polarized protection scenarios.
What PCB layout considerations are critical for optimal performance of the TPSMP7.5HM3/84A?
Optimal performance requires mounting the TPSMP7.5HM3/84A on 5.0 mm × 5.0 mm copper pads per terminal to meet specified thermal and surge ratings. Short, low-inductance traces to ground minimize clamping overshoot, and cathode-band orientation must match schematic polarity. Avoid thermal relief on pads to ensure full power dissipation capability. These guidelines are validated in the TPSMP7.5HM3/84A datasheet and essential for achieving rated 300 W pulse handling.
