Product details
Overview
TPSMP22AHE3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for automotive-grade circuit protection. It features a breakdown voltage range of 20.9 V to 23.1 V at 1 mA test current, clamps up to 30.6 V at 13.1 A peak pulse current, and delivers 400 W peak pulse power with 1.0 mm profile height - ideal for protecting sensor signal lines and drive transistors in harsh automotive environments.
For engineers reviewing the TPSMP22AHE3/84A datasheet, TPSMP22AHE3/84A pinout, TPSMP22AHE3/84A application, or TPSMP22AHE3/84A equivalent, key selection criteria include its AEC-Q101 qualification, low incremental surge resistance, 185 °C maximum junction temperature, and RoHS-compliant matte tin terminals meeting J-STD-002 solderability standards.
Technical Context
This TVS diode uses Vishay's patented PAR oxide passivated chip construction to achieve excellent clamping capability and very fast response time under transient events. Its unidirectional configuration provides robust overvoltage protection for DC-biased lines such as automotive sensor supply rails and microcontroller I/O interfaces.
The device operates across -65 °C to +185 °C junction temperature range and meets MSL Level 1 per J-STD-020 with 260 °C lead-free reflow compatibility. Its DO-220AA package enables high power density surface mount placement on FR-4 PCBs with 5.0 × 5.0 mm copper pads per terminal for optimal thermal performance.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A | DO-214AC package; 22 V nominal VBR; 400 W PPPM; higher profile (2.3 mm); not AEC-Q101 qualified | Used in industrial/commercial power supplies where automotive qualification is unnecessary | Select SMAJ22A only when AEC-Q101 compliance and ultra-low height are not required |
| TPSMP22AHM3/84A | Same electrical specs and DO-220AA package; differs only in tape-and-reel packaging (84A vs. HM3 suffix denotes different reel size) | No functional difference - identical in circuit behavior and mounting | Choose TPSMP22AHM3/84A if alternate reel format aligns with SMT line feeder requirements |
Compared with SMAJ22A and TPSMP22AHM3/84A, the TPSMP22AHE3/84A uniquely combines AEC-Q101 qualification, 1.0 mm height, and JESD201 Class 2 whisker resistance - making it the only choice for next-generation automotive sensor nodes requiring both miniaturization and long-term field reliability.

FAQ
What is the clamping voltage of the TPSMP22AHE3/84A at its rated peak pulse current?
The TPSMP22AHE3/84A clamps to a maximum of 30.6 V at 13.1 A peak pulse current under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream components remain within safe operating voltage limits during surge events. The TPSMP22AHE3/84A achieves this with low incremental surge resistance inherent to its PAR oxide passivated chip design.
Is the TPSMP22AHE3/84A suitable for automotive applications requiring AEC-Q101 qualification?
Yes, the TPSMP22AHE3/84A is explicitly qualified to AEC-Q101 for automotive use, as confirmed in Vishay document 88471. Its qualification covers temperature cycling, high-temperature reverse bias (HTRB), and ESD testing. The TPSMP22AHE3/84A is intended for deployment in engine compartments, ADAS sensors, and body control modules where reliability under thermal and mechanical stress is mandatory.
What does the HE3/84A suffix indicate in TPSMP22AHE3/84A?
The HE3 suffix denotes RoHS-compliant, high-reliability automotive grade construction with matte tin plating and JESD201 Class 2 whisker resistance. The 84A indicates the preferred package code for 7-inch diameter plastic tape-and-reel delivery containing 3000 units. Both elements are defined in Vishay's ordering information table and confirm manufacturing and packaging compliance for automated SMT assembly.
How does the TPSMP22AHE3/84A compare to bidirectional TVS diodes in sensor protection?
The TPSMP22AHE3/84A is unidirectional and optimized for DC-biased lines like sensor VCC or analog outputs, offering lower leakage (<1.0 µA) and tighter VBR tolerance than comparable bidirectional devices. Unlike bidirectional TVS diodes, the TPSMP22AHE3/84A avoids conduction during normal reverse bias - critical for preserving signal fidelity in precision automotive sensor interfaces.
What PCB layout guidance applies to the TPSMP22AHE3/84A for optimal thermal performance?
Vishay specifies 5.0 × 5.0 mm copper pads attached to each terminal for thermal derating validation. To maintain rated 400 W pulse power, minimize trace length between the TPSMP22AHE3/84A and ground plane, use internal copper layers for heat spreading, and avoid thermal isolation. The DO-220AA footprint must follow Vishay's recommended pad dimensions in Document 91000 to ensure solder joint reliability and thermal dissipation.
