Product details
Overview
TMPG06-18AHE3/73 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in automotive and industrial power rails and signal lines. It features a 17.1–18.9 V breakdown voltage (VBR), 15.3 V stand-off voltage (VWM), 400 W peak pulse power (10/1000 µs), 15.9 A peak pulse current (IPPM), and clamps to ≤25.5 V at rated surge, enabling reliable protection of MOSFETs and sensor interfaces against inductive switching transients.
For engineers reviewing the TMPG06-18AHE3/73 datasheet, TMPG06-18AHE3/73 pinout, TMPG06-18AHE3/73 application, or TMPG06-18AHE3/73 equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C max junction temperature, low 0.088 %/°C VBR temperature coefficient, and MPG06 package compatibility with high-reliability automotive PCB layouts.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, entering avalanche conduction when reverse voltage exceeds VBR. Its low incremental resistance and fast response time (<1 ns) ensure minimal overshoot during ESD or load-dump events.
Rated for 400 W peak pulse power under 10/1000 µs waveform with 0.01 % duty cycle, it sustains repetitive surges only within derated limits above 25 °C ambient-power dissipation drops to zero at 175 °C per Fig. 2, and IPPM de-rates linearly with junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 17.1 V / 18.9 V - defines minimum clamping onset threshold and maximum guaranteed avalanche initiation voltage at 1 mA test current |
| VWM | 15.3 V - maximum continuous reverse operating voltage before significant leakage; sets safe DC bias margin below breakdown |
| IPPM | 15.9 A - peak surge current it safely clamps at 10/1000 µs waveform; determines minimum series impedance needed for target energy absorption |
| VC @ IPPM | ≤25.5 V - maximum clamped voltage during rated surge; directly limits stress on downstream ICs or MOSFETs |
| PPPM | 400 W - peak pulse power handling capability; validates suitability for ISO 7637-2 Pulse 1/2a/5a automotive transient suppression |
| TJ max | +185 °C - enables operation in under-hood automotive environments without thermal shutdown or parameter drift |
| AEC-Q101 | Qualified - certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD47 |
Pinout & Package
Package: MPG06 - molded epoxy case with matte tin-plated leads, UL 94 V-0 rated, 0.100" (2.54 mm) lead pitch, 1.0" (25.4 mm) minimum tape reel length. Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / low-side reference node | Connected to ground or low-voltage rail; establishes reference for clamping action during reverse transient |
| Cathode | Reverse voltage input / protected line connection | Connected to line being protected (e.g., 12 V battery rail); avalanche conduction occurs between cathode and anode when VREV > VBR |

Use Scenario: Shielding PoE-powered Ethernet switches from lightning-induced surges on 48 V DC feeder lines. IC Role / Device Role / Timing Role: Standoff-rated protector on DC input rail, selected for VWM = 15.3 V to allow stacking in series for higher voltage coverage. Use Value: Enables modular protection design: two TMPG06-18AHE3/73 devices in series achieve ~30.6 V standoff while retaining full 400 W per-device pulse rating. |
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 | Same VWM (15.3 V), but lower PPPM (400 W vs. SMAJ18A's 400 W), identical MPG06 footprint, slightly higher VC (29.2 V vs. 25.5 V) | Less effective clamping margin for sensitive 3.3 V logic; requires tighter layout to manage higher VC-induced stress | Select TMPG06-18AHE3/73 when lower clamping voltage is required to protect sub-20 V logic rails without additional series impedance. |
| 1.5SMC18A | Higher PPPM (1500 W), larger SMC package (7.11 × 6.22 mm), same VBR range, VC = 29.2 V, not AEC-Q101 qualified | Not suitable for space-constrained automotive modules; lacks automotive reliability validation for long-term field deployment | Choose TMPG06-18AHE3/73 for AEC-Q101-compliant designs where board area and thermal profile constrain use of larger packages. |
Compared with SMAJ18A and 1.5SMC18A, TMPG06-18AHE3/73 delivers superior clamping performance (25.5 V vs. ≥29.2 V) in the same compact MPG06 footprint while providing automotive-grade qualification-critical for protecting low-voltage microcontrollers in harsh environments without increasing PCB area or compromising reliability.

FAQ
What is the maximum clamping voltage of TMPG06-18AHE3/73 at its rated peak pulse current?
The maximum clamping voltage (VC) of TMPG06-18AHE3/73 is 25.5 V when subjected to its rated peak pulse current (IPPM) of 15.9 A under the standard 10/1000 µs waveform. This value is measured per Figure 3 in the official Vishay datasheet 88404 and represents the upper limit of voltage seen by protected circuitry during worst-case transient events. Designers must ensure downstream components tolerate this clamped level.
Is TMPG06-18AHE3/73 qualified for automotive applications?
Yes, TMPG06-18AHE3/73 is AEC-Q101 qualified, as explicitly stated in the Vishay datasheet revision 17-Sep-2021 (Document Number: 88404). This qualification covers stress tests including high-temperature reverse bias, temperature cycling, and electrostatic discharge-confirming its suitability for under-hood and chassis-mounted automotive electronics such as body control modules and ADAS sensor interfaces.
What does the "HE3/73" suffix indicate in TMPG06-18AHE3/73?
The "HE3" suffix denotes RoHS-compliant, matte tin-plated leads meeting J-STD-002 solderability and JESD 201 Class 2 whisker resistance; "73" is Vishay's internal packaging code indicating 13-inch diameter paper tape and reel delivery with 5500 units per reel. Both elements are defined in the Ordering Information section of the TMPG06-10A–43A datasheet.
Can TMPG06-18AHE3/73 be used in bidirectional configurations?
No, TMPG06-18AHE3/73 is unidirectional only, as confirmed in the Features section of the datasheet. It conducts in reverse avalanche mode to clamp positive transients on the cathode side but provides no protection against negative-going surges on the anode. For bidirectional protection, two devices must be connected in series opposing configuration-or a dedicated bidirectional TVS like SMBJ18CA must be selected instead.
What is the thermal derating behavior of TMPG06-18AHE3/73 above 25 °C ambient?
TMPG06-18AHE3/73 follows linear derating per Figure 2 in the datasheet: peak pulse power (PPPM) decreases from 400 W at 25 °C to zero at 175 °C junction temperature. At 125 °C, PPPM is approximately 200 W. Designers must calculate actual junction temperature using thermal resistance and power dissipation to ensure operation remains within the derated envelope during repetitive surge conditions.
