Product details
Overview
TPSMP8.2AHE3/84A from Vishay General Semiconductor is a unidirectional automotive-grade transient voltage suppressor (TVS) in DO-220AA (SMP) package, with 7.79 V to 8.61 V breakdown voltage (VBR), 7.02 V standoff voltage (VWM), 50 µA max reverse leakage at VWM, and 24.8 V clamping voltage (VC) at 200 A peak pulse current - designed for robust ESD and surge protection of automotive sensor signal lines.
For engineers reviewing the TPSMP8.2AHE3/84A datasheet, TPSMP8.2AHE3/84A pinout, TPSMP8.2AHE3/84A application, or TPSMP8.2AHE3/84A equivalent, key selection criteria include AEC-Q101 qualification, 300 W peak pulse power rating (10/1000 µs), low-profile 1.0 mm height, matte tin-plated leads compliant with J-STD-002, and RoHS/WEEE compliance for high-reliability automotive PCB designs.
Technical Context
The TPSMP8.2AHE3/84A employs Vishay's patented PAR oxide-passivated chip construction to achieve low incremental surge resistance and excellent clamping performance under fast transient events. Its unidirectional configuration enables precise overvoltage protection on DC-biased lines without forward conduction interference.
Rated for operation from −65 °C to +185 °C junction temperature and qualified to AEC-Q101, it supports automotive environments where thermal cycling, vibration, and long-term reliability are critical. The device meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow compatibility and passes JESD201 Class 2 whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 7.79 V / 8.61 V - ensures reliable triggering above normal operating voltage while avoiding false trips during transients |
| VWM | 7.02 V - maximum continuous reverse working voltage compatible with 5 V–7 V automotive sensor supply rails |
| VC @ IPPM | 24.8 V @ 200 A - limits downstream IC voltage stress during ISO 7637-2 Pulse 1/2a/5a surges |
| PPPM | 300 W (10/1000 µs) - sustains high-energy transients common in 12 V vehicle electrical systems |
| IR @ VWM | 50 µA max - minimizes standby power loss and avoids loading of high-impedance sensor outputs |
| TJ max | +185 °C - supports under-hood placement near ECUs, actuators, and powertrain modules |
| Package | DO-220AA (SMP) - ultra-low profile (1.0 mm typical height), optimized for automated SMT placement and space-constrained modules |
Pinout & Package
DO-220AA (SMP) surface-mount package with cathode indicated by color band; terminals are matte tin-plated, solderable per J-STD-002 and JESD22-B102, and qualified to JESD201 Class 2 for whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| UL 94 V-0 molding compound | Meets flammability requirements for under-hood and cabin-mounted electronics |
Applications
| Automotive Sensor Signal Protection | Engine Control Unit (ECU) I/O Protection |
|---|---|
Use Scenario: Protecting analog output lines of pressure, temperature, and position sensors exposed to load dump and ISO 7637-2 transients in 12 V vehicle networks. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed between sensor output and ECU input, clamping surges before they reach precision ADC front-end. Use Value: Maintains signal integrity with ≤50 µA leakage at 7.02 V, preventing offset errors in millivolt-level sensor signals. | Use Scenario: Safeguarding digital and analog I/O pins of microcontrollers in engine management systems against battery reversal, jump-start spikes, and alternator load dump. IC Role / Device Role / Timing Role: Primary overvoltage clamp on LIN bus lines, PWM actuator drivers, and throttle position feedback paths. Use Value: 24.8 V clamping at 200 A ensures MCU GPIOs remain below absolute maximum ratings during 100 V/50 ms load dump events. |
| Body Control Module (BCM) Communication Lines | Advanced Driver Assistance Systems (ADAS) Camera Interface |
Use Scenario: Protecting CAN FD and LIN communication lines in door modules, seat controllers, and lighting ECUs from ESD and conducted noise. IC Role / Device Role / Timing Role: Secondary protection stage after common-mode chokes, absorbing differential-mode transients on low-speed buses. Use Value: Fast response time and 300 W pulse rating handle repetitive ESD events (IEC 61000-4-2 ±15 kV contact) without degradation. | Use Scenario: Shielding MIPI CSI-2 data lanes and power rails in surround-view camera modules mounted near bumpers and wheel wells. IC Role / Device Role / Timing Role: Point-of-load TVS on image sensor power supply and serializer/deserializer signal pairs. Use Value: 1.0 mm height allows placement directly adjacent to connectors and flex circuits without interfering with lens housing or sealing gaskets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ8.0A | Higher VBR (7.22–8.02 V), lower PPPM (400 W only for ≥13 V variants; SMAJ8.0A rated at 400 W but with higher VC = 12.5 V @ 32.4 A) | Not AEC-Q101 qualified; intended for industrial/commercial use only | Select when automotive qualification is not required and cost sensitivity outweighs long-term reliability validation needs |
| TPSMA8.2A | Same VBR/VWM/VC specs, but in larger DO-214AC (SMA) package (2.3 mm height, 4.5 mm length) | Lower power density; less suitable for space-constrained ADAS or sensor modules | Select when board layout accommodates larger footprint and thermal mass is prioritized over Z-height |
Compared with SMAJ8.0A and TPSMA8.2A, the TPSMP8.2AHE3/84A delivers automotive-grade reliability in the smallest footprint, enabling next-generation compact sensor nodes - whereas SMAJ8.0A lacks AEC-Q101 validation and TPSMA8.2A sacrifices 58% height reduction for marginal thermal improvement.

FAQ
What is the AEC-Q101 qualification status of the TPSMP8.2AHE3/84A?
The TPSMP8.2AHE3/84A is fully AEC-Q101 qualified, as confirmed in Vishay document 88471. This includes stress testing for temperature cycling, high-temperature operating life, unbiased highly accelerated stress test (uHAST), and mechanical shock - all performed per AEC-Q101 Rev D requirements. The HE3 suffix explicitly denotes high-reliability automotive grade, and the device carries full certification documentation traceable to Vishay's qualified manufacturing sites.
Does the TPSMP8.2AHE3/84A have a bidirectional variant?
No, the TPSMP8.2AHE3/84A is unidirectional only, as stated in the "FEATURES" section of Vishay document 88471. It is designed for DC-biased signal or power lines where clamping occurs only in reverse polarity. For bidirectional protection, Vishay offers separate part numbers such as TPSMP8.2CAHE3/84A - which is not interchangeable with TPSMP8.2AHE3/84A due to different internal structure and polarity marking.
What is the maximum clamping voltage of the TPSMP8.2AHE3/84A and at what current is it specified?
The maximum clamping voltage (VC) of the TPSMP8.2AHE3/84A is 24.8 V, measured at 200 A peak pulse current (IPPM) using a 10/1000 µs waveform, per Table 1 in Vishay document 88471. This value is guaranteed across temperature and represents worst-case clamping performance under standardized surge conditions relevant to ISO 7637-2 testing.
Can the TPSMP8.2AHE3/84A be used in 24 V commercial vehicle applications?
The TPSMP8.2AHE3/84A is rated for 7.02 V standoff and 24.8 V clamping - making it unsuitable as primary protection in 24 V systems where VWM must exceed nominal rail voltage. It is intended for 12 V automotive subsystems (e.g., sensors, body modules). For 24 V applications, Vishay specifies higher-voltage variants like TPSMP24AHE3/84A (VWM = 20.5 V) or TPSMP27AHE3/84A (VWM = 23.1 V).
What does the "84A" in TPSMP8.2AHE3/84A indicate?
The "84A" is Vishay's preferred package code denoting 7-inch diameter plastic tape-and-reel packaging containing 3000 units, as defined in the "ORDERING INFORMATION" section of document 88471. It reflects the delivery format and quantity - not an electrical or reliability variant. The "HE3" suffix confirms RoHS compliance, AEC-Q101 qualification, and JESD201 Class 2 whisker resistance.
