Product details
Overview
TMPG06-18AHE3_A/B 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), 25.5 V clamping voltage at 15.9 A, and AEC-Q101 qualification - deployed to safeguard MOSFETs and sensor interfaces against inductive switching transients.
For engineers reviewing the TMPG06-18AHE3_A/B datasheet, TMPG06-18AHE3_A/B pinout, TMPG06-18AHE3_A/B application, or TMPG06-18AHE3_A/B equivalent, key selection criteria include verified clamping performance under 10/1000 µs surge, unidirectional polarity alignment with DC-biased protection paths, AEC-Q101 compliance for automotive ECUs, and MPG06 package thermal derating above 25 °C.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR (17.1–18.9 V), it avalanches to limit transient energy across protected nodes. Its low incremental resistance ensures stable clamping at 25.5 V up to 15.9 A IPPM, while the 0.088 %/°C VBR temperature coefficient maintains predictable threshold drift across -65 °C to +185 °C junction range.
Designed for high-reliability environments, the device sustains 40 A IFSM non-repetitive forward surge (8.3 ms half-sine), withstands solder dip at 275 °C for 10 s per JESD22-B106, and meets JESD201 Class 2 whisker resistance via matte tin-plated leads - all within the UL 94 V-0 compliant MPG06 epoxy package.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ18A | Same VWM (15.3 V) and VC (29.2 V), but lower PPPM (600 W vs. 400 W); SMB package (larger footprint, higher thermal mass) | Higher surge margin but requires PCB rework due to different pad layout and 3.5 mm lead spacing | Select when higher single-pulse energy tolerance is required and board space allows SMB outline |
| 1.5SMC18A | Identical VBR range and VC, but rated for 1500 W PPPM; SMC package (7.11 × 6.22 mm vs. MPG06's 4.57 × 3.25 mm) | Superior power handling for heavy industrial surge classes, but incompatible with MPG06 land pattern | Choose for mission-critical 2 kV+ surge immunity where footprint expansion is acceptable |
Compared with SMBJ18A and 1.5SMC18A, TMPG06-18AHE3_A/B delivers AEC-Q101 qualification and tighter thermal derating in a smaller DO-214AC footprint - making it optimal for space-constrained automotive modules where qualification and size outweigh raw wattage.

FAQ
What is the maximum clamping voltage of the TMPG06-18AHE3_A/B under standard test conditions?
The TMPG06-18AHE3_A/B has a maximum clamping voltage (VC) of 25.5 V when subjected to its rated peak pulse current (IPPM) of 15.9 A using the 10/1000 µs waveform. This value is measured at TA = 25 °C and ensures downstream circuitry remains within safe voltage limits during transient events. The TMPG06-18AHE3_A/B achieves this with low incremental resistance and tight VBR distribution (17.1–18.9 V).
Is TMPG06-18AHE3_A/B qualified for automotive applications?
Yes, TMPG06-18AHE3_A/B is AEC-Q101 qualified, meaning it has passed stress tests including high-temperature reverse bias, temperature cycling, and humidity bias for use in automotive electronics. Its +185 °C maximum junction temperature and robust construction make TMPG06-18AHE3_A/B suitable for engine control units, body modules, and ADAS sensor interfaces where reliability under thermal and mechanical stress is critical.
What does the "HE3_A/B" suffix indicate in TMPG06-18AHE3_A/B?
The "HE3" suffix denotes RoHS-compliant, matte tin-plated leads that meet JESD201 Class 2 whisker resistance requirements, while "A/B" indicates the revision code per Vishay's internal manufacturing documentation. TMPG06-18AHE3_A/B is fully compatible with lead-free reflow and wave soldering processes, and both revisions share identical electrical and thermal specifications per Document Number 88404.
Can TMPG06-18AHE3_A/B be used in bidirectional protection configurations?
No - TMPG06-18AHE3_A/B is specified for unidirectional polarity only, with cathode marked by a color band. It is not rated for reverse standoff or clamping in the forward direction. For bidirectional protection, two TMPG06-18AHE3_A/B devices must be connected in series opposition, or a dedicated bidirectional TVS such as SMBJ18CA should be selected instead.
What is the thermal derating behavior of TMPG06-18AHE3_A/B above 25 °C ambient?
TMPG06-18AHE3_A/B follows a linear derating curve from 100 % power at TA = 25 °C down to 0 % at TA ≈ 150 °C, per Figure 2 in Vishay Document 88404. At 75 °C ambient, its peak pulse power rating remains at approximately 70 % of 400 W (i.e., ~280 W), and its DC power dissipation (PD) is limited to 1.0 W only when mounted on an infinite heatsink at TL = 75 °C.
