Product details
Overview
TMPG06-18HE3/54 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 18.9 V maximum 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 current - enabling reliable suppression of load-dump and inductive-switching transients in 12 V systems.
For engineers reviewing the TMPG06-18HE3/54 datasheet, TMPG06-18HE3/54 pinout, TMPG06-18HE3/54 application, or TMPG06-18HE3/54 equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C max junction temperature, low 0.088 %/°C VBR temperature coefficient, unidirectional polarity with cathode band marking, and MPG06 package compatibility with high-reliability automotive PCB layouts.
Technical Context
The TMPG06-18HE3/54 operates as a silicon avalanche diode with fast response time (<1 ns) and low dynamic impedance, delivering precise clamping during transient events without latch-up. Its unidirectional structure blocks reverse voltage up to 15.3 V in normal operation and conducts only when reverse voltage exceeds 17.1–18.9 V (VBR range).
It is rated for 40 A non-repetitive forward surge current (IFSM) and dissipates 1.0 W continuously at TL = 75 °C, with thermal derating above 25 °C per Figure 2. The device meets JESD 201 Class 2 whisker resistance and JESD 22-B106 solder dip requirements (275 °C, 10 s), confirming suitability for lead-free reflow and under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 17.1 V / 18.9 V - defines minimum and maximum voltage at which avalanche conduction begins at 1 mA test current; ensures consistent turn-on across temperature and lot variation |
| VWM | 15.3 V - maximum continuous reverse operating voltage; must exceed system nominal voltage (e.g., 12 V automotive) with margin to avoid leakage-induced power loss |
| IPPM (10/1000 µs) | 15.9 A - peak current it safely clamps during standardized lightning/inductive-spike waveform; determines minimum trace width and fuse coordination |
| VC @ IPPM | 25.5 V - clamped voltage seen by protected IC/MOSFET during full-rated transient; must stay below downstream component absolute maximum ratings |
| PPPM | 400 W - peak pulse power handling capability; validates survivability against ISO 7637-2 Pulse 1, 2a, 5a/b waveforms in automotive applications |
| TJ max | +185 °C - maximum junction temperature rating; enables operation in engine bay or power supply hotspots without thermal shutdown |
| αVBR | 0.088 %/°C - temperature coefficient of breakdown voltage; ensures stable clamping threshold across -65 °C to +185 °C operating range |
Pinout & Package
Package: MPG06 - molded epoxy case with matte tin-plated leads, UL 94 V-0 rated, 0.115–0.125 inch (2.92–3.18 mm) body width, 0.023–0.026 inch (0.584–0.66 mm) lead diameter, 1.0 inch (25.4 mm) minimum lead length.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path); carries surge current during reverse-transient clamping |
| Cathode | Reverse-biased clamping terminal | Marked with color band; connected to protected line (e.g., 12 V rail or sensor input); initiates avalanche conduction when voltage exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including HTOL, TC, UHAST, and ESD testing - required for under-hood and safety-critical ECUs |
| 400 W peak pulse power (10/1000 µs) | Withstands repeated ISO 7637-2 transients without degradation; eliminates need for external series impedance in many 12 V supply protection designs |
| Low incremental resistance | Ensures tight VC–VBR spread (25.5 V clamp at 15.9 A vs. 18.9 V VBR max), minimizing voltage overshoot on protected nodes |
| JESD 201 Class 2 whisker resistance | Prevents tin whisker growth under thermal cycling and humidity stress - critical for long-life automotive modules (>15 years) |
| High TJ max (185 °C) | Supports placement near power MOSFETs, DC/DC converters, or motor drivers without thermal derating penalties |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|

Use Scenario: Suppressing inductive kickback from brushed DC motors in smart home appliances (e.g., vacuum cleaners, washing machines). IC Role / Device Role: Flyback TVS across motor terminals or H-bridge high-side FET drain-source. Use Value: Absorbs 40 A IFSM surge energy without failure, extending MOSFET lifetime and eliminating need for snubber RC networks in cost-sensitive BOMs. |
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), SMA package (smaller footprint, lower thermal mass) | Less suitable for sustained high-temperature environments due to lower TJ max (150 °C vs. 185 °C); not AEC-Q101 qualified | Select SMAJ18A only for non-automotive, space-constrained consumer designs where thermal cycling reliability is secondary |
| 1.5KE18A | Higher PPPM (1500 W), larger DO-201 package, same VWM/VBR range, but no AEC-Q101 qualification and higher VC (29.7 V) | Used in legacy industrial power supplies; incompatible with automated SMT assembly due to axial leads and larger footprint | Choose 1.5KE18A only for through-hole prototyping or high-energy surge zones where PCB real estate and RoHS compliance are not constraints |
Compared with SMAJ18A and 1.5KE18A, the TMPG06-18HE3/54 delivers automotive-grade reliability (AEC-Q101), superior thermal endurance (185 °C), and SMT-compatible MPG06 packaging - making it the optimal choice for production automotive modules, industrial controllers, and any design requiring long-term field stability under thermal stress.

FAQ
What is the exact breakdown voltage range for TMPG06-18HE3/54?
The TMPG06-18HE3/54 has a guaranteed breakdown voltage (VBR) range of 17.1 V to 18.9 V at 1.0 mA test current, measured at 25 °C. This range reflects manufacturing tolerance and ensures consistent clamping behavior across production lots while maintaining compatibility with 12 V system margins. The TMPG06-18HE3/54 datasheet specifies this range in Table 1 under ELECTRICAL CHARACTERISTICS.
Is TMPG06-18HE3/54 suitable for bidirectional transient protection?
No - the TMPG06-18HE3/54 is unidirectional only, with cathode marked by a color band. It protects against reverse-polarity transients on positive rails but does not suppress positive-going transients on grounded lines. For bidirectional protection, a separate device such as the SMBJ18CA or dual-diode array would be required. The TMPG06-18HE3/54 product documentation explicitly states "Available in unidirectional polarity only" in the FEATURES section.
What does the "HE3/54" suffix indicate in TMPG06-18HE3/54?
The "HE3" suffix denotes RoHS-compliant, matte tin-plated leads meeting J-STD-002 solderability and JESD 201 Class 2 whisker resistance requirements. The "/54" indicates tape-and-reel packaging per EIA-481 standard, with 5500 units per reel - confirmed in the ORDERING INFORMATION table of the Vishay document 88404. The TMPG06-18HE3/54 is not a variant with altered electrical specs; the suffix defines packaging and plating only.
How does TMPG06-18HE3/54 perform at elevated temperatures?
The TMPG06-18HE3/54 maintains specified performance up to +185 °C junction temperature, with VBR shifting predictably at +0.088 %/°C. Derating curves (Figure 2) show 100 % PPPM capability at 25 °C, decreasing to ~65 % at 125 °C and ~40 % at 175 °C. This behavior is fully characterized and validated per AEC-Q101, making the TMPG06-18HE3/54 suitable for under-hood automotive use where ambient temperatures exceed 105 °C.
Can TMPG06-18HE3/54 replace older P6KE18A in existing designs?
Direct replacement is not recommended without validation: the TMPG06-18HE3/54 uses MPG06 surface-mount packaging versus P6KE18A's axial DO-15, and has tighter VC (25.5 V vs. 29.7 V) and higher TJ max (185 °C vs. 175 °C). While electrical parameters overlap, mechanical fit, thermal profile, and AEC-Q101 qualification differ. Redesign verification is required before substituting TMPG06-18HE3/54 into legacy P6KE18A layouts.
