Product details
Overview
TMPG06-33AHE3_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 31.4–34.7 V breakdown voltage (VBR), 28.2 V stand-off voltage (VWM), 400 W peak pulse power (10/1000 µs), 8.8 A peak pulse current (IPPM), and clamps to ≤45.7 V at rated surge - deployed on engine control units, sensor interfaces, and 12 V/24 V DC systems.
For engineers reviewing the TMPG06-33AHE3_A/B datasheet, TMPG06-33AHE3_A/B pinout, TMPG06-33AHE3_A/B application, or TMPG06-33AHE3_A/B equivalent, key selection criteria include AEC-Q101 qualification, 185 °C max junction temperature, low incremental resistance, fast response time, and compatibility with high-reliability automotive PCB layouts requiring RoHS-compliant, whisker-tested matte tin leads.
Technical Context
This TVS diode operates exclusively in unidirectional polarity, with cathode denoted by a color band. Its silicon junction is encapsulated in UL 94 V-0 compliant molded epoxy (MPG06 package), enabling stable clamping under repetitive transients up to 0.01% duty cycle and 400 W peak power per 10/1000 µs waveform.
It delivers 1.0 W steady-state power dissipation on infinite heatsink at TL = 75 °C, withstands 40 A non-repetitive forward surge (8.3 ms half-sine), and maintains <3.5 V forward voltage at 25 A - supporting protection of MOSFETs, ICs, and sensor signal paths against inductive switching spikes and load dump events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 31.4 V / 34.7 V - defines minimum voltage at which device enters avalanche conduction; ensures reliable triggering above system operating voltage (28.2 V VWM) |
| VC @ IPPM | ≤45.7 V - maximum clamped voltage during 8.8 A surge; determines protected circuit's peak stress level |
| PPPM | 400 W - peak transient energy handling capability with 10/1000 µs waveform; validates suitability for ISO 7637-2 Pulse 1/2a/5a compliance testing |
| IFSM | 40 A - surge current rating for 8.3 ms half-sine wave; supports protection against battery reverse connection or alternator load dump |
| TJ max | +185 °C - maximum junction temperature; enables operation in under-hood automotive environments without derating |
| AEC-Q101 | Qualified - certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22 standards |
| Package | MPG06 - axial-leaded, surface-mount compatible outline with 0.115–0.125 inch lead diameter; optimized for automated placement and reflow |
Pinout & Package
MPG06 package: axial-leaded, molded epoxy body with cathode indicated by color band; leads are matte tin plated, solderable per J-STD-002 and JESD 22-B102, and qualified to JESD 201 Class 2 whisker test.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive terminal in forward bias; connected to protected line or ground return path | Accepts surge current during reverse-biased clamping; must be routed with low-inductance trace to minimize overshoot |
| Cathode | Negative terminal; marked by color band; connected to system ground or lower-potential rail | Serves as reference node for clamping action; requires solid grounding to sustain 45.7 V clamp performance under 8.8 A surge |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional polarity | Enables precise clamping only during reverse overvoltage events - avoids interference with normal forward-biased operation of downstream circuits |
| 400 W peak pulse power (10/1000 µs) | Supports immunity to high-energy transients such as ISO 16750-2 Load Dump (up to 35 V × 12 A × 400 ms equivalent energy) |
| AEC-Q101 qualification | Validates long-term reliability in automotive applications including temperature cycling (-40 °C to +125 °C), humidity, and mechanical shock |
| Low incremental resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns response), improving protection margin for sensitive 3.3 V or 5 V logic interfaces |
| RoHS-compliant & whisker-tested (JESD 201 Class 2) | Ensures solder joint integrity and process compatibility in lead-free reflow profiles up to 260 °C peak temperature |
Applications
| Automotive Engine Control Unit (ECU) Power Input | Industrial Sensor Signal Line Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ33A-E3/5A (Vishay) | Same VBR range (31.4–34.7 V), but SMA package (surface-mount, smaller footprint); 400 W rating, 8.8 A IPPM, but lower IFSM (30 A vs. 40 A) | Better suited for space-constrained PCBs; less robust for high-current load dump events due to lower surge rating | Select when board area is critical and surge currents remain below 30 A; verify thermal relief for continuous 1.0 W dissipation |
| 1.5KE33A (ON Semiconductor) | Through-hole DO-201 package; identical VBR/VC specs and 400 W rating, but higher VF (3.5 V at 25 A) and no AEC-Q101 qualification | Acceptable for industrial/commercial use; not validated for automotive temperature cycling or humidity reliability requirements | Choose for cost-sensitive non-automotive designs where AEC-Q101 is not mandated; confirm lead finish compatibility with assembly process |
Compared with SMAJ33A-E3/5A and 1.5KE33A, TMPG06-33AHE3_A/B uniquely combines AEC-Q101 qualification, 40 A IFSM, and MPG06 axial-leaded form factor - making it optimal for automotive under-hood applications requiring both mechanical ruggedness and high-reliability validation.

FAQ
What is the clamping voltage of TMPG06-33AHE3_A/B at its rated peak pulse current?
The TMPG06-33AHE3_A/B clamps to a maximum of 45.7 V when subjected to its rated 8.8 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and guarantees the protected circuit sees no more than this voltage during transient events - critical for safeguarding 3.3 V or 5 V logic interfaces downstream of the device.
Is TMPG06-33AHE3_A/B qualified for automotive applications?
Yes, TMPG06-33AHE3_A/B is AEC-Q101 qualified, meaning it has passed rigorous stress tests including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD) per JESD22 standards. This certification confirms its suitability for automotive powertrain, body electronics, and ADAS modules where reliability under thermal and mechanical stress is essential.
What does the "HE3_A/B" suffix indicate in TMPG06-33AHE3_A/B?
The "HE3" suffix denotes RoHS-compliant construction with matte tin-plated leads that meet JESD 201 Class 2 whisker resistance, while "A/B" specifies the revision code per Vishay's internal documentation. Both revisions share identical electrical specifications, thermal ratings, and mechanical dimensions - the difference reflects minor process or material updates verified to maintain full functional and form-fit compatibility.
Can TMPG06-33AHE3_A/B be used in bidirectional protection configurations?
No - TMPG06-33AHE3_A/B is specified for unidirectional polarity only, with cathode identified by a color band. It conducts and clamps only during reverse-biased overvoltage events. For bidirectional protection (e.g., AC lines or differential buses), two devices must be connected in series opposition, or a dedicated bidirectional TVS such as SMBJ33CA should be selected instead.
What is the maximum steady-state power dissipation for TMPG06-33AHE3_A/B?
TMPG06-33AHE3_A/B has a maximum steady-state power dissipation (PD) of 1.0 W when mounted on an infinite heatsink at lead temperature (TL) = 75 °C. Derating is required above this temperature per Figure 5 in the datasheet; at 125 °C TL, usable PD drops to approximately 0.5 W - a key constraint for continuous surge duty or high-ambient industrial deployments.
