Product details
Overview
TPSMP7.5HE3/85A from Vishay General Semiconductor is a unidirectional automotive-grade transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, with 7.5 V breakdown voltage (VBR), 300 W peak pulse power (10/1000 µs), 25.6 V clamping voltage at 500 A, and AEC-Q101 qualification for engine control units and sensor protection.
For engineers reviewing the TPSMP7.5HE3/85A datasheet, TPSMP7.5HE3/85A pinout, TPSMP7.5HE3/85A application, or TPSMP7.5HE3/85A equivalent, key selection criteria include clamping performance under 10/1000 µs surge, low-profile mounting compatibility with automated SMT lines, and automotive reliability validation per JESD201 Class 2 whisker testing and MSL Level 1 reflow profile.
Technical Context
This TVS diode uses patented PAR oxide-passivated chip construction to achieve low incremental surge resistance and fast response time (<1 ns), enabling effective suppression of ESD and load-dump transients in automotive electronics. Its unidirectional configuration provides forward conduction path during overvoltage events while maintaining low leakage (<150 µA at 6.05 V).
Designed for surface-mount placement on FR-4 PCBs with 5.0 × 5.0 mm copper pads per terminal, the device operates across -65 °C to +185 °C junction temperature range and delivers stable clamping up to 150 °C ambient, with 0.060 %/°C VBR temperature coefficient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 6.75 V / 8.25 V - defines reliable avalanche initiation window under 10 mA test current |
| VWM | 6.05 V - maximum continuous reverse operating voltage before leakage exceeds 150 µA |
| VC @ IPPM | 25.6 V at 500 A - clamping voltage limits downstream IC stress during ISO 7637-2 Pulse 1/2a/5a events |
| PPPM | 300 W (10/1000 µs) - sustains automotive load-dump surges without thermal runaway |
| IFSM | 40 A - withstands 10 ms half-sine surge common in alternator fault conditions |
| TJ max | +185 °C - supports under-hood placement near powertrain modules |
| MSL Level | Level 1 (260 °C peak) - compatible with standard lead-free reflow profiles without baking |
Pinout & Package
Package: DO-220AA (SMP), ultra-low-profile surface-mount case with 1.0 mm typical height, matte tin-plated leads, cathode indicated by color band. Meets UL 94 V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path during transient | Connects to protected line (e.g., CAN_H, LIN, sensor supply); conducts surge current to ground when VBR exceeded |
| Cathode | Reference terminal / clamping node | Connected to system ground; establishes precise clamping threshold relative to ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Patented PAR oxide passivation | Enables consistent avalanche behavior and long-term reliability under repetitive surge stress |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, HTRB, and mechanical shock per JEDEC standards |
| Low incremental surge resistance | Minimizes VC overshoot during high-di/dt transients, improving protection margin for 3.3 V/5 V logic |
| JESD201 Class 2 whisker resistance | Prevents tin whisker growth in high-humidity under-hood environments over 15+ year service life |
Applications
| Engine Control Unit (ECU) Power Input | Automotive CAN Bus Line Protection |
|---|---|
Use Scenario: Protects 12 V supply rail of engine control module against ISO 7637-2 Pulse 5a (load dump up to 60 V, 400 ms). IC Role / Device Role: Unidirectional TVS clamps excess energy to ground while allowing normal 12 V operation. Use Value: Limits rail voltage to ≤25.6 V during 500 A surge, preventing damage to MCU, LDOs, and gate drivers. | Use Scenario: Shields high-speed CAN_H/CAN_L differential pair from ESD (IEC 61000-4-2 ±8 kV contact) and board-level transients. IC Role / Device Role: Paired unidirectional TVS devices clamp each line independently to chassis ground. Use Value: Maintains signal integrity with <150 µA leakage at 6.05 V, avoiding CAN bus bias disruption. |
| Body Control Module Sensor Interface | Automotive LIN Bus Transceiver Protection |
Use Scenario: Safeguards analog inputs (e.g., temperature, pressure sensors) connected to BCM against cable discharge events. IC Role / Device Role: Low-capacitance TVS placed at connector entry point to shunt ESD before signal conditioning circuitry. Use Value: Clamps 8 kV ESD pulse within 1 ns, limiting voltage excursion to 25.6 V and preserving ADC accuracy. | Use Scenario: Protects LIN transceiver pins (e.g., TXD, RXD, BUS) from battery connection reversal and jump-start spikes. IC Role / Device Role: Unidirectional suppressor referenced to ground handles negative-going transients on single-wire bus. Use Value: Withstands 40 A IFSM, enabling robust protection against 12 V reverse polarity faults without fuse dependency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.5A-E3/5A | Higher VC = 12.9 V at 43.3 A; lower PPPM = 400 W but rated for 10/1000 µs waveform only at 7.5 V | Not AEC-Q101 qualified; intended for industrial/commercial use only | Select for cost-sensitive non-automotive designs where AEC-Q101 is not mandated |
| TPSMP7.5AHE3/85A | Narrower VBR range (7.13–7.88 V vs. 6.75–8.25 V); tighter tolerance improves clamping consistency | Same DO-220AA package and AEC-Q101 qualification; optimized for higher-reliability ECUs | Choose when tighter breakdown voltage control is required for precision rail protection |
Compared with SMAJ7.5A-E3/5A and TPSMP7.5AHE3/85A, the TPSMP7.5HE3/85A offers broader VBR tolerance and proven under-hood reliability via AEC-Q101, making it optimal for mainstream automotive power rail protection where cost and qualification balance is critical.

FAQ
What is the clamping voltage of the TPSMP7.5HE3/85A at its rated peak pulse current?
The TPSMP7.5HE3/85A has a maximum clamping voltage (VC) of 25.6 V at 500 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value ensures downstream components like microcontrollers and transceivers remain within safe operating voltage limits during standardized automotive surge events such as ISO 7637-2 Pulse 1 and Pulse 5a. The TPSMP7.5HE3/85A achieves this with low incremental surge resistance enabled by its patented PAR oxide passivation.
Is the TPSMP7.5HE3/85A qualified for automotive applications?
Yes, the TPSMP7.5HE3/85A is AEC-Q101 qualified and designated as high-reliability/automotive grade per its HE3 suffix. It meets JESD201 Class 2 whisker testing, MSL Level 1 reflow capability (260 °C peak), and operates across -65 °C to +185 °C junction temperature range. These qualifications confirm the TPSMP7.5HE3/85A for under-hood and safety-critical systems including engine control units and ADAS sensor interfaces.
What does the "HE3/85A" suffix indicate in TPSMP7.5HE3/85A?
The "HE3" suffix denotes RoHS-compliant, high-reliability/automotive-grade construction meeting AEC-Q101 requirements and JESD201 Class 2 whisker resistance. The "/85A" indicates packaging in 13-inch diameter plastic tape and reel with 10,000 units per reel. This packaging format ensures compatibility with high-speed SMT placement equipment used in Tier 1 automotive electronics manufacturing. The TPSMP7.5HE3/85A is fully traceable and validated for automated assembly processes.
How does the TPSMP7.5HE3/85A compare to the TPSMP7.5AHE3/85A variant?
The TPSMP7.5HE3/85A has a wider breakdown voltage range (6.75–8.25 V) versus the TPSMP7.5AHE3/85A (7.13–7.88 V), offering greater process tolerance for cost-sensitive designs. Both share identical DO-220AA package, AEC-Q101 qualification, and 300 W PPPM. The TPSMP7.5HE3/85A is preferred for general-purpose automotive rail protection, while the "A" variant suits applications demanding tighter VBR control. Neither is pin-to-pin interchangeable due to differing marking codes and test bins.
What is the maximum steady-state power dissipation of the TPSMP7.5HE3/85A?
The TPSMP7.5HE3/85A has a maximum steady-state power dissipation (PD) of 2.5 W when mounted on an infinite heatsink at TA = 75 °C. On standard FR-4 PCB with Vishay-recommended 5.0 × 5.0 mm copper pads per terminal, derating applies per Figure 6 in datasheet 88471. This PD rating supports continuous operation in thermally managed automotive modules, and the TPSMP7.5HE3/85A maintains functionality up to +185 °C junction temperature.
