Product details
Overview
TMPG06-18AHE3_A/D 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 delivers 400 W peak pulse power (10/1000 µs), clamps at 25.5 V under 15.9 A surge, and operates across -65 °C to +185 °C with AEC-Q101 qualification for under-hood automotive use.
For engineers reviewing the TMPG06-18AHE3_A/D datasheet, TMPG06-18AHE3_A/D pinout, TMPG06-18AHE3_A/D application, or TMPG06-18AHE3_A/D equivalent, key selection criteria include its 17.1–18.9 V breakdown range, 15.3 V stand-off voltage, low 1.0 µA leakage at VWM, 3.5 V max forward voltage at 25 A, and MPG06 package compatibility with high-reliability PCB assembly.
Technical Context
This TVS diode uses a passivated silicon junction in a molded epoxy MPG06 case, optimized for fast response (<1 ns) and low incremental resistance to limit transient-induced voltage overshoot. Its unidirectional polarity and color-band cathode marking support clear board-level orientation during automated placement.
The device meets JESD 22-B106 (275 °C solder dip, 10 s) and JESD 201 Class 2 whisker testing, with thermal derating defined up to 185 °C junction temperature. Its 1.0 W steady-state power dissipation enables continuous operation in thermally constrained environments when used within specified ambient and lead-temperature limits.

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) and VC (29.2 V), but lower PPPM (400 W same), higher IFSM (40 A same), SMA package (surface-mount) | Requires PCB redesign for SMD layout; lacks AEC-Q101 qualification | Select for space-constrained consumer designs where automotive qualification is not required |
| TPSMF18A | Same VWM (15.3 V), slightly higher VC (27.7 V), identical PPPM (400 W), SOD-123FL package, AEC-Q101 qualified | Surface-mount alternative with tighter footprint; lower thermal mass affects sustained surge handling | Select when automated SMT assembly and board density outweigh axial-lead mechanical robustness needs |
Compared with SMAJ18A and TPSMF18A, the TMPG06-18AHE3_A/D provides proven axial-lead mechanical stability for high-vibration environments, maintains identical surge ratings, and delivers AEC-Q101 assurance without requiring layout changes-making it optimal for legacy automotive harness interfaces and industrial field-wire terminations.

FAQ
What is the breakdown voltage range of the TMPG06-18AHE3_A/D?
The TMPG06-18AHE3_A/D has a guaranteed breakdown voltage (VBR) range of 17.1 V to 18.9 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This tolerance ensures consistent clamping behavior across production lots and supports design margining for 12 V automotive systems where nominal rail voltages may vary.
Is the TMPG06-18AHE3_A/D qualified for automotive applications?
Yes, the TMPG06-18AHE3_A/D is AEC-Q101 qualified, meaning it has passed stress tests for temperature cycling, humidity, mechanical shock, and high-temperature operating life required for automotive under-hood and chassis-mounted electronics. Its +185 °C maximum junction temperature further validates suitability for engine control and transmission control units.
What does the "HE3_A/D" suffix indicate in TMPG06-18AHE3_A/D?
The "HE3_A/D" suffix denotes RoHS-compliant construction (HE3), AEC-Q101 qualification, JESD 201 Class 2 whisker resistance, and revision code "A" per Vishay's ordering nomenclature. The "/D" indicates tape-and-reel packaging per 13-inch diameter reel with 5500-unit base quantity, optimized for automated SMT placement despite its axial-lead form factor.
How does the clamping voltage of TMPG06-18AHE3_A/D compare to its stand-off voltage?
The TMPG06-18AHE3_A/D has a stand-off voltage (VWM) of 15.3 V and a maximum clamping voltage (VC) of 25.5 V at 15.9 A. This 10.2 V differential ensures safe margin above normal operating voltage while limiting transient overshoot to levels compatible with 3.3 V and 5 V logic interfaces, making it suitable for protecting both power rails and low-voltage signal paths.
Can TMPG06-18AHE3_A/D be used in bidirectional protection circuits?
No, the TMPG06-18AHE3_A/D is unidirectional only, as confirmed in its datasheet features and electrical characteristics table. It protects against positive transients on the cathode side relative to anode. For bidirectional protection, two devices in series opposition or a dedicated bidirectional TVS such as SMBJ18CA would be required instead of the TMPG06-18AHE3_A/D.
