Product details
Overview
TPSMP15HM3/84A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-220AA (SMP) package, designed for high-reliability automotive and industrial surge protection. It features a 13.5 V to 16.3 V breakdown voltage (VBR), 22.0 V clamping voltage (VC) at 18.2 A peak pulse current (IPPM), and 400 W peak pulse power (10/1000 µs), enabling robust ESD and lightning surge suppression on 12 V DC power rails and signal lines.
For engineers reviewing the TPSMP15HM3/84A datasheet, TPSMP15HM3/84A pinout, TPSMP15HM3/84A application, or TPSMP15HM3/84A equivalent, this device is selected for AEC-Q101-qualified 12 V system protection where low-profile mounting (1.0 mm height), TJ = 185 °C operation, and MSL Level 1 reflow compatibility are critical design requirements.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for low incremental surge resistance and fast response time (<1 ns), delivering precise clamping during transient events without thermal runaway. Its unidirectional polarity and cathode band marking ensure correct PCB orientation for reverse-biased protection of downstream ICs and transistors.
The device operates across -65 °C to +185 °C junction temperature range and is rated for 40 A non-repetitive forward surge current (IFSM). Its 2.5 W steady-state power dissipation (PD) and 1.0 µA max reverse leakage at VWM = 12.1 V support reliable long-term operation in thermally constrained environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 13.5 V / 16.3 V - defines minimum voltage at which clamping activates; ensures protection starts before damage threshold of 12 V systems |
| VC @ IPPM | 22.0 V at 18.2 A - maximum voltage seen by protected circuit during 10/1000 µs surge; stays below typical 24 V IC absolute max ratings |
| PPPM | 400 W - peak transient energy handling capacity; supports IEC 61000-4-5 Level 4 (4 kV) surge testing on 12 V lines |
| VWM | 12.1 V - maximum continuous reverse operating voltage; allows safe operation across full 12 V automotive battery range (9–16 V) |
| IR @ VWM | 1.0 µA - ultra-low leakage preserves battery life in always-on automotive modules and sensor nodes |
| TJ max | +185 °C - enables under-hood deployment without derating in engine control units and body electronics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ15A | DO-214AC (SMA) package; 15.0 V VBR min, 24.4 V VC at 16.3 A; 400 W PPPM; 1.5 mm height | Larger footprint and height; lower thermal performance (TJ max = 150 °C); not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification and board space constraints |
| TPSMA6.8A | Same DO-220AA package; lower VBR (6.45–7.14 V); 23.8 V VC at 500 A; 300 W PPPM; same 185 °C rating | Designed for 5 V logic rail protection; unsuitable for 12 V systems due to premature clamping | Select only for 3.3 V/5 V interface protection; not interchangeable with TPSMP15HM3/84A in 12 V applications |
Compared with SMAJ15A and TPSMA6.8A, TPSMP15HM3/84A delivers superior automotive readiness (AEC-Q101), tighter thermal margin (+185 °C), and smaller form factor (1.0 mm height), making it the preferred choice for next-generation 12 V power rail protection where reliability and miniaturization are prioritized.

FAQ
What is the clamping voltage of TPSMP15HM3/84A and how does it protect downstream components?
The TPSMP15HM3/84A has a maximum clamping voltage (VC) of 22.0 V at 18.2 A peak pulse current (10/1000 µs waveform). This ensures that during transient events-such as load dump or ESD-the voltage presented to downstream ICs, regulators, or transistors remains safely below their absolute maximum ratings (e.g., typical 24 V tolerance), preventing latch-up or permanent damage. The low incremental surge resistance contributes to tight clamping consistency across pulse amplitudes.
Is TPSMP15HM3/84A suitable for automotive applications and what qualifications does it hold?
Yes, TPSMP15HM3/84A is explicitly AEC-Q101 qualified and rated for junction temperatures up to +185 °C, making it suitable for under-hood and chassis-mounted automotive electronics. It meets MSL Level 1 reflow requirements (260 °C peak), uses halogen-free and RoHS-compliant materials, and is constructed with passivated anisotropic rectifier technology validated for automotive reliability stress tests including temperature cycling and humidity bias.
What is the package type and physical size of TPSMP15HM3/84A?
TPSMP15HM3/84A uses the DO-220AA (SMP) surface-mount package, measuring 3.61 mm × 1.88 mm × 1.0 mm (L × W × H). Its ultra-low 1.0 mm profile enables placement in height-constrained modules like ADAS camera housings and compact power supplies. The cathode is marked by a visible color band, and terminals are matte tin-plated for compatibility with J-STD-002 soldering processes.
How does the breakdown voltage range of TPSMP15HM3/84A affect its use in 12 V systems?
The TPSMP15HM3/84A has a specified breakdown voltage (VBR) range of 13.5 V to 16.3 V at 1.0 mA test current. This ensures reliable activation above nominal 12 V battery voltage (including cold-crank dips to ~9 V and charging peaks to ~14.8 V), while avoiding false triggering during normal operation. Its 12.1 V stand-off voltage (VWM) provides adequate margin for sustained 12 V rail operation without leakage-induced power loss.
Can TPSMP15HM3/84A be used in place of older SMAJ15A TVS diodes?
TPSMP15HM3/84A offers functional equivalence in 12 V protection but is not a direct drop-in replacement for SMAJ15A due to different package dimensions (DO-220AA vs. DO-214AC) and thermal characteristics. While both deliver 400 W peak power, TPSMP15HM3/84A provides higher junction temperature rating (+185 °C vs. +150 °C), AEC-Q101 qualification, and lower profile-requiring PCB layout revision but enabling improved reliability and space savings in new designs.
