Product details
Overview
TPSMP22AHM3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor diode in DO-220AA (SMP) package, designed for high-reliability automotive and industrial surge protection. It features 22 V nominal breakdown voltage (20.9–23.1 V), 30.6 V clamping voltage at 13.1 A peak pulse current, 400 W peak pulse power rating, and 185 °C maximum junction temperature - enabling robust ESD and lightning surge protection on signal lines and power rails.
For engineers reviewing the TPSMP22AHM3/84A datasheet, TPSMP22AHM3/84A pinout, TPSMP22AHM3/84A application, or TPSMP22AHM3/84A equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, MSL Level 1 moisture sensitivity, 1.0 mm profile for space-constrained PCBs, and compatibility with automated SMT placement per J-STD-002 solderability standards.
Technical Context
This device uses passivated anisotropic rectifier technology to achieve low incremental surge resistance and fast response time (<1 ns), critical for protecting sensitive downstream ICs from transient overvoltages. Its TJ = 185 °C rating supports operation in under-hood automotive environments and industrial enclosures with elevated ambient temperatures.
The DO-220AA (SMP) package delivers high power density with minimal footprint (2.67 mm × 1.27 mm) and low thermal resistance, while the matte tin-plated terminals ensure reliable solder joints per JESD 22-B102 and J-STD-002. The color band denotes cathode polarity, and HM3 suffix confirms halogen-free, RoHS-compliant, and AEC-Q101-qualified construction.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ22A-E3/5AT | DO-214AC (SMA) package; 22 V VBR; 400 W PPPM; 1.9 mm height vs. 1.0 mm | Larger footprint and height limit use in ultra-thin modules; same AEC-Q101 qualification | Choose SMAJ22A-E3/5AT only if DO-220AA placement equipment is unavailable or legacy layout reuse is required. |
| TPSMA6.8A-Q | Same DO-220AA package but 6.8 V VBR; lower clamping (10.5 V); 300 W PPPM | Designed for 5 V logic-level protection; unsuitable for 12–24 V systems due to premature conduction | Select TPSMA6.8A-Q only for low-voltage digital interfaces; TPSMP22AHM3/84A remains optimal for 18–24 V power/signal lines. |
Compared with SMAJ22A-E3/5AT and TPSMA6.8A-Q, the TPSMP22AHM3/84A offers superior power density and board-space efficiency in automotive and industrial designs requiring 22 V standoff, while maintaining identical AEC-Q101 reliability and surge robustness.

FAQ
What is the breakdown voltage tolerance for TPSMP22AHM3/84A?
The TPSMP22AHM3/84A has a specified breakdown voltage range of 20.9 V to 23.1 V at 1 mA test current, corresponding to ±5 % tolerance. This tight tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage protection design in 12 V and 24 V automotive systems where margin control is critical.
Is TPSMP22AHM3/84A suitable for bidirectional transient protection?
No, TPSMP22AHM3/84A is strictly unidirectional. Its electrical characteristics - including VBR, VC, and IR - are defined only for reverse-bias operation. For bidirectional protection, a pair of unidirectional devices or a dedicated bidirectional TVS such as SMBJ22CA must be used; using TPSMP22AHM3/84A in bidirectional configurations risks catastrophic failure during positive transients.
Does TPSMP22AHM3/84A require a heatsink for 2.5 W steady-state dissipation?
No, the 2.5 W power dissipation rating for TPSMP22AHM3/84A applies only under infinite heatsink conditions at TA = 75 °C. In real-world PCB layouts with standard copper pads (5.0 mm × 5.0 mm per terminal), thermal derating applies - actual continuous power handling is ~0.5 W. TPSMP22AHM3/84A is intended for transient, not steady-state, power dissipation; sustained DC power must remain well below 100 mW.
What does the "HM3/84A" suffix indicate in TPSMP22AHM3/84A?
The "HM3" suffix denotes halogen-free, RoHS-compliant, AEC-Q101-qualified construction with matte tin plating and JESD 201 Class 2 whisker resistance. "84A" specifies the packaging: 3000-piece 7-inch plastic tape-and-reel format with EIA-481 compliance. This ensures compatibility with high-speed pick-and-place machines and meets automotive supply chain traceability requirements.
How does TPSMP22AHM3/84A perform under high-temperature operating conditions?
TPSMP22AHM3/84A maintains full specification compliance up to +185 °C junction temperature. At elevated ambient temperatures (e.g., 125 °C under hood), its VBR increases linearly with a +0.092 %/°C coefficient, and clamping voltage rises predictably - enabling accurate worst-case analysis in thermal-aware protection schemes without derating for reliability loss.
