Product details
Overview
TMPG06-33HE3/73 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 31.4 V to 34.7 V breakdown voltage (VBR), 28.2 V maximum working 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 DC-DC converter inputs.
For engineers reviewing the TMPG06-33HE3/73 datasheet, TMPG06-33HE3/73 pinout, TMPG06-33HE3/73 application, or TMPG06-33HE3/73 equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C max junction temperature, low incremental resistance, fast response time, and unidirectional polarity with cathode band marking - critical for automotive-grade ESD and load-dump protection design validation.
Technical Context
This TVS diode operates as a voltage-clamping device that enters avalanche conduction when reverse voltage exceeds its specified breakdown range (31.4–34.7 V). Its low dynamic impedance ensures effective suppression of transients up to 400 W under standardized 10/1000 µs waveform conditions, with thermal derating applied above 25 °C ambient per Figure 2.
The device uses a passivated silicon junction encapsulated in UL 94 V-0 compliant molded epoxy (MPG06 package), with matte tin-plated leads qualified to JESD 201 Class 2 whisker test and solderable per J-STD-002. Its unidirectional configuration provides asymmetric clamping optimized for DC-biased circuits where reverse polarity stress must be blocked and forward surge handled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 31.4 V / 34.7 V - defines precise avalanche onset window for reliable triggering without premature conduction |
| VWM | 28.2 V - maximum continuous reverse voltage before leakage exceeds 1 µA, ensuring no interference during normal operation |
| IPPM | 8.8 A - peak surge current it safely clamps at 45.7 V, directly supporting ISO 7637-2 Pulse 1/2a/5a compliance testing |
| PPPM | 400 W - peak pulse power handling capability under 10/1000 µs waveform, enabling protection against inductive switching spikes |
| TJ max | +185 °C - extended junction temperature rating supports under-hood automotive deployment without thermal derating penalties |
| Leakage (ID) | ≤1.0 µA at VWM, ≤5.0 µA at 150 °C - minimal standby power loss and stable threshold behavior across temperature |
| AEC-Q101 | Qualified - validated for automotive electronics per stress test requirements including HTGB, HTRB, and TCT |
Pinout & Package
Package: MPG06 - axial-leaded, molded epoxy case with cathode band marking; dimensions: 2.54 mm diameter × 25.4 mm min length; UL 94 V-0 rated; RoHS-compliant and lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / low-side reference | Connected to ground or lower-potential node in unidirectional clamp configuration |
| Cathode | Reverse voltage sensing / clamping output | Marked by color band; connected to protected line - conducts avalanche current when VREV > VBR |
Key Features
| Feature | Design Value |
|---|---|

| 400 W peak pulse power (10/1000 µs) | Supports robust protection against ISO 7637-2 load-dump and inductive switch-off transients |
| Low clamping voltage (VC ≤ 45.7 V) | Minimizes stress on downstream ICs like MCUs and CAN transceivers during surge events |
| 185 °C maximum junction temperature | Enables direct placement near heat sources (e.g., power MOSFETs, ignition coils) without thermal throttling |
| Matte tin plating + JESD 201 Class 2 | Ensures long-term solder joint reliability and mitigates tin whisker risk in high-vibration environments |
Applications
| Automotive Engine Control Unit (ECU) | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Protection of 12 V supply rail against load-dump transients (ISO 7637-2 Pulse 5a) during alternator disconnection. IC Role / Device Role: Primary clamping element placed between battery input and DC-DC regulator input stage. Use Value: Limits voltage excursion to ≤45.7 V, preventing damage to 40 V-rated buck controllers and microcontrollers. |

IC Role / Device Role: Series-connected TVS on return path to clamp common-mode transients relative to chassis ground. Use Value: Stable VBR tolerance (±5 %) and 185 °C rating ensure performance retention in sealed outdoor cabinets. |
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 | Same VWM (28.2 V) and VC (53.3 V), but lower PPPM (400 W same), SMC package (larger footprint) | Not AEC-Q101 qualified; suited for commercial/industrial only | Select if automotive qualification is not required and board space allows SMC outline |
| TPSMA6L33A | Higher VC (53.3 V), same VWM, AEC-Q101 qualified, but lower IPPM (7.5 A at 400 W) | Designed for lower-energy transients; less margin for severe load-dump events | Prefer for cost-sensitive automotive designs where full 8.8 A IPPM headroom is unnecessary |
Compared with SMAJ33A and TPSMA6L33A, the TMPG06-33HE3/73 delivers identical peak power handling with superior thermal robustness (185 °C vs. 150 °C), tighter VBR tolerance, and axial-leaded form factor ideal for through-hole high-reliability harness connections.

FAQ
What is the breakdown voltage range for TMPG06-33HE3/73?
The TMPG06-33HE3/73 has a guaranteed breakdown voltage (VBR) range of 31.4 V to 34.7 V at 1.0 mA test current, measured per ANSI/IEEE C62.35. This tight tolerance ensures consistent clamping behavior across production lots and supports precise overvoltage margining in 24 V automotive systems where the TMPG06-33HE3/73 is commonly deployed.
Is TMPG06-33HE3/73 qualified for automotive applications?
Yes, TMPG06-33HE3/73 is AEC-Q101 qualified per the Vishay datasheet revision 17-Sep-2021 (Document Number: 88404). It has passed stress tests including high-temperature reverse bias, temperature cycling, and humidity testing - confirming suitability for under-hood and body-control module applications where the TMPG06-33HE3/73 is routinely specified.
What is the maximum clamping voltage of TMPG06-33HE3/73 at rated surge current?
The maximum clamping voltage (VC) of TMPG06-33HE3/73 is 45.7 V at 8.8 A peak pulse current (IPPM) under 10/1000 µs waveform conditions. This value is critical for ensuring downstream components - such as 40 V-rated DC-DC converters - remain within safe operating limits during transient events, and is explicitly verified in the electrical characteristics table for the TMPG06-33HE3/73.
Does TMPG06-33HE3/73 have unidirectional or bidirectional polarity?
TMPG06-33HE3/73 is unidirectional only, with cathode indicated by a color band on the MPG06 package. Its electrical characteristics - including VBR, VWM, and IPPM - are defined for reverse-biased operation only; forward conduction follows standard diode behavior with VF = 3.5 V at 25 A. This polarity configuration makes the TMPG06-33HE3/73 appropriate for DC-biased protection circuits.
What is the package type and lead finish of TMPG06-33HE3/73?
TMPG06-33HE3/73 uses the MPG06 axial-leaded package: molded epoxy case with UL 94 V-0 flammability rating, 2.54 mm diameter, and minimum 25.4 mm length. Its leads are matte tin plated, compliant with J-STD-002 and JESD 22-B102 solderability standards, and qualified to JESD 201 Class 2 for whisker resistance - all confirmed in the mechanical data section of the TMPG06-33HE3/73 datasheet.
