Product details
Overview
TPSMP22A-E3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor diode in DO-220AA (SMP) package, designed for automotive-grade overvoltage 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 W steady-state power dissipation - ideal for protecting sensor signal lines and drive transistors in automotive ECUs.
For engineers reviewing the TPSMP22A-E3/84A datasheet, TPSMP22A-E3/84A pinout, TPSMP22A-E3/84A application, or TPSMP22A-E3/84A equivalent, key selection criteria include its AEC-Q101 qualified high-reliability grade (E3 suffix), low-profile 1.0 mm height, MSL Level 1 moisture sensitivity, and 185 °C maximum junction temperature for under-hood deployment.
Technical Context
The TPSMP22A-E3/84A operates as a unidirectional avalanche diode with patented PAR oxide passivated chip construction, enabling low incremental surge resistance and fast response time to transient events. Its electrical behavior is defined by precise breakdown voltage (VBR) tolerance (±5%), tight clamping voltage (VC = 30.6 V @ IPPM = 13.1 A), and stable temperature coefficient of 0.092 %/°C.
It complies with J-STD-020C MSL Level 1, supports solder dip at 260 °C for 40 seconds, and meets RoHS 2002/95/EC and WEEE 2002/96/EC directives. The cathode is marked by a color band, and terminals are matte tin plated per J-STD-002B and JESD22-B102D.
Key Specifications

Applications
| Automotive Engine Control Unit (ECU) | Industrial Sensor Interface Module |
|---|---|
Use Scenario: Protecting LIN bus transceiver inputs from load dump and jump-start induced surges in under-hood ECUs. IC Role / Device Role: Unidirectional TVS diode placed between LIN line and ground, triggered above 20.9 V. Use Value: Clamps transient to ≤30.6 V within nanoseconds, preserving transceiver integrity without adding capacitance that degrades 19.2 kbps signaling. | Use Scenario: Safeguarding 4–20 mA current loop analog inputs in factory automation sensors exposed to relay coil flyback. IC Role / Device Role: Standoff voltage (18.8 V) isolates normal operation; avalanche conduction activates only during >20.9 V faults. Use Value: 1.0 µA leakage at 18.8 V prevents loop current error; 400 W PPPM absorbs 100 mJ pulses without degradation. |
| Automotive Camera Module | Consumer Appliance Motor Driver |
Use Scenario: Shielding MIPI CSI-2 data lines in ADAS cameras from ESD events during assembly and field use. IC Role / Device Role: Low-capacitance unidirectional clamp referenced to camera module's 2.8 V or 3.3 V rail. Use Value: 1.0 mm profile avoids mechanical interference with lens housing; 0.092 %/°C VBR TC ensures stable clamping across -40 °C to +125 °C ambient. | Use Scenario: Suppressing inductive kickback from brushed DC motor commutation in smart home appliances. IC Role / Device Role: Connected anode-to-ground, cathode-to-motor supply rail to clamp reverse EMF spikes. Use Value: 40 A IFSM rating handles repeated 10 ms surges; DO-220AA footprint allows automated placement alongside SMT MOSFET drivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A | DO-214AC (SMA) package; 300 W PPPM; VBR = 22.2–24.5 V; higher profile (2.29 mm) | Larger footprint and lower surge rating; less suitable for space-constrained automotive modules | Choose SMAJ22A only if board layout already uses SMA footprints and 300 W rating suffices. |
| TPSMD22A | DO-218AB (SMC) package; 500 W PPPM; VBR = 22.2–24.5 V; 2.6 mm height | Higher power handling but incompatible footprint; requires PCB redesign | Select TPSMD22A when system-level surge requirements exceed 400 W and thermal mass permits larger package. |
Compared with SMAJ22A and TPSMD22A, the TPSMP22A-E3/84A uniquely balances ultra-low profile (1.0 mm), AEC-Q101 qualification, and 400 W surge capability in DO-220AA - making it optimal for next-generation compact automotive electronics where height and reliability are non-negotiable.

FAQ
What is the exact breakdown voltage range of the TPSMP22A-E3/84A?
The TPSMP22A-E3/84A has a guaranteed breakdown voltage range of 20.9 V to 23.1 V at 1 mA test current, measured per ANSI/IEEE C62.35 standards. This ±5% tolerance ensures consistent triggering behavior across production lots and temperature extremes, directly supporting design margin calculations for automotive signal line protection.
Is the TPSMP22A-E3/84A qualified for automotive use?
Yes, the TPSMP22A-E3/84A carries the E3 suffix indicating commercial-grade qualification per AEC-Q101. It is explicitly rated for automotive applications, including engine control units and ADAS modules, with full validation for temperature cycling, humidity bias, and surge endurance per the AEC-Q101 standard.
What does the "84A" in TPSMP22A-E3/84A indicate?
The "84A" denotes the preferred package code specifying 7-inch diameter plastic tape-and-reel packaging with a base quantity of 3,000 units. This format is optimized for high-speed pick-and-place assembly and aligns with Vishay's standard logistics for DO-220AA devices used in automotive production lines.
How does the clamping performance of TPSMP22A-E3/84A compare to its stand-off voltage?
The TPSMP22A-E3/84A has a stand-off voltage (VWM) of 18.8 V and clamps to 30.6 V at 13.1 A (10/1000 µs). This 11.8 V differential provides sufficient margin above VWM to avoid false triggering while limiting downstream voltage to a safe level - critical for protecting 24 V automotive ICs rated for ≤33 V absolute maximum.
Can TPSMP22A-E3/84A be used in bidirectional configurations?
No, the TPSMP22A-E3/84A is strictly unidirectional, as confirmed by Vishay's documentation and device marking. Its internal structure supports conduction only from cathode to anode during overvoltage events. For bidirectional protection, a separate symmetric TVS array or back-to-back diode configuration is required.
