Product details
Overview
TMPG06-18A-E3/73 from Vishay General Semiconductor is a unidirectional automotive-grade transient voltage suppressor (TVS) diode in MPG06 package, with 17.1 V to 18.9 V breakdown voltage (VBR), 25.5 V clamping voltage (VC) at 15.9 A peak pulse current, 400 W peak pulse power (10/1000 µs), and 185 °C maximum junction temperature. It protects MOSFETs and sensor signal lines in automotive powertrain control units against inductive switching transients.
For engineers reviewing the TMPG06-18A-E3/73 datasheet, TMPG06-18A-E3/73 pinout, TMPG06-18A-E3/73 application, or TMPG06-18A-E3/73 equivalent, key selection criteria include clamping performance under 10/1000 µs surge, low leakage (<1.0 µA at 15.3 V), AEC-Q101 qualification status, and compatibility with reflow and wave soldering per J-STD-002B.
Technical Context
This TVS diode employs Vishay's patented PAR® construction for stable clamping under high-temperature stress (TJ up to +185 °C) and exhibits low incremental surge resistance to minimize voltage overshoot during fast transients. Its unidirectional polarity and 1.0 µA max reverse leakage at VWM = 15.3 V support precision protection in low-power sensor interfaces.
The device delivers 25.5 V clamping at IPPM = 15.9 A with a 10/1000 µs waveform and maintains <0.088 %/°C temperature coefficient of VBR, ensuring predictable overvoltage response across automotive operating ranges (-65 °C to +185 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 17.1 V / 18.9 V - ensures reliable conduction onset above system nominal voltage while avoiding false triggering |
| VC @ IPPM | 25.5 V at 15.9 A - limits downstream voltage stress to safe levels for 24 V automotive ICs |
| PPPM | 400 W (10/1000 µs) - handles standard ISO 7637-2 Pulse 1 & 2a transient energy without degradation |
| IFSM | 40 A (8.3 ms half-sine) - withstands repetitive load-dump surges in engine control modules |
| TJ max. | +185 °C - supports placement near high-heat sources like power MOSFETs in under-hood ECUs |
| ID @ VWM | <1.0 µA at 15.3 V - prevents signal integrity loss in high-impedance sensor bias networks |
| Temp. Coeff. VBR | 0.088 %/°C - enables stable clamping threshold across full automotive temperature range |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ18A | Lower PPPM (400 W same), but higher VC (29.2 V), larger SMA package (4.5 × 2.7 mm vs. MPG06 9.5 × 3.18 mm) | Less effective clamping margin for 24 V systems; not AEC-Q101 qualified | Select TMPG06-18A-E3/73 when automotive qualification and tighter clamping are required |
| TPSMF18A | Same VBR range and VC, but SOD-123FL package (smaller footprint), lower IFSM (30 A), no AEC-Q101 grade option | Better for space-constrained consumer designs; unsuitable for under-hood thermal environments | Choose TMPG06-18A-E3/73 for high-temperature, high-surge automotive deployments |
Compared with SMAJ18A and TPSMF18A, TMPG06-18A-E3/73 provides superior thermal robustness (185 °C TJ max), AEC-Q101 qualification, and lower clamping voltage-critical for protecting modern 24 V automotive electronics where voltage margins are shrinking.

FAQ
What is the clamping voltage of TMPG06-18A-E3/73 at its rated peak pulse current?
The TMPG06-18A-E3/73 has a maximum clamping voltage (VC) of 25.5 V at 15.9 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that downstream circuitry sees no more than 25.5 V during surge events, making it suitable for protecting 24 V automotive ICs with 30 V absolute maximum ratings. The TMPG06-18A-E3/73 achieves this with low dynamic impedance inherent to its PAR® structure.
Is TMPG06-18A-E3/73 qualified for automotive applications?
Yes, TMPG06-18A-E3/73 carries the E3/73 suffix indicating commercial-grade packaging with AEC-Q101 qualification. It has been tested and certified for automotive use, including temperature cycling, high-temperature operating life, and mechanical shock per AEC-Q101 Rev D. The device operates reliably from -65 °C to +185 °C junction temperature and meets ISO 7637-2 transient immunity requirements-key for engine control, transmission, and ADAS modules. TMPG06-18A-E3/73 is not a generic industrial TVS but an automotive-qualified part.
What does the "A" in TMPG06-18A-E3/73 signify?
The "A" in TMPG06-18A-E3/73 denotes the tighter breakdown voltage tolerance variant: 17.1 V (min) to 18.9 V (max) at 1.0 mA test current, versus the non-A version (TMPG06-18) which spans 16.2 V to 19.8 V. This ±5.5 % tolerance ensures more precise clamping onset in safety-critical automotive circuits where overvoltage margin must be tightly controlled. All electrical characteristics-including VC, ID, and tempco-are specified for the "A" variant in the official Vishay Document 88404. TMPG06-18A-E3/73 is the preferred choice for designs requiring repeatable surge response.
Can TMPG06-18A-E3/73 be used in both 12 V and 24 V automotive systems?
Yes, TMPG06-18A-E3/73 is designed for dual-voltage compatibility: its 15.3 V standoff voltage (VWM) safely isolates it from 12 V nominal systems, while its 25.5 V clamping voltage provides adequate margin below the 30 V rating of most 24 V automotive power ICs. It withstands load-dump transients up to 60 V and meets ISO 16750-2 test pulses for both voltage classes. The TMPG06-18A-E3/73 is commonly deployed in gateway ECUs, battery management systems, and hybrid powertrain controllers where dual-rail support is essential.
What is the maximum reverse leakage current for TMPG06-18A-E3/73 at operating temperature?
The TMPG06-18A-E3/73 specifies a maximum reverse leakage current (ID) of 1.0 µA at its 15.3 V standoff voltage (VWM) and 25 °C ambient. At elevated temperatures, leakage increases-up to 10 µA at TJ = 150 °C-but remains well below thresholds that would disturb high-impedance sensor bias networks or ADC reference paths. This low leakage is confirmed in Vishay Document 88404 Table "Electrical Characteristics" and is critical for maintaining accuracy in automotive cabin and chassis sensor interfaces. TMPG06-18A-E3/73 maintains this performance across its full qualified temperature range.
