Product details
Overview
TMPG06-33AHE3/53 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), 45.7 V clamping voltage at 8.8 A, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the TMPG06-33AHE3/53 datasheet, TMPG06-33AHE3/53 pinout, TMPG06-33AHE3/53 application, or TMPG06-33AHE3/53 equivalent, key selection criteria include clamping performance under 10/1000 µs transients, unidirectional polarity compatibility with DC-biased lines, thermal stability up to +185 °C junction temperature, and RoHS-compliant, whisker-tested matte tin terminations.
Technical Context
This TVS diode operates as a shunt-clamping device that remains high-impedance below VWM (28.2 V) and rapidly avalanches above VBR (min. 31.4 V) to limit transient voltages. Its low incremental resistance and sub-nanosecond response time ensure effective suppression of inductive switching spikes and ESD events.
The MPG06 package supports high-temperature operation (TJ = –65 °C to +185 °C) and meets UL 94 V-0 flammability requirements. It is rated for 40 A non-repetitive forward surge current (8.3 ms half-sine) and derates linearly above 25 °C ambient per Figure 2 in the datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 31.4 V / 34.7 V - defines minimum avalanche initiation threshold and maximum variation across production lot at 1 mA test current |
| VWM | 28.2 V - maximum continuous reverse operating voltage before significant leakage; ensures no conduction during normal DC bias |
| VC @ IPPM | 45.7 V at 8.8 A - clamped voltage during 10/1000 µs transient; determines protected circuit's maximum stress level |
| PPPM | 400 W - peak pulse power handling capability; defines survivability against standardized lightning/surge waveforms |
| IFSM | 40 A - single half-sine surge rating (8.3 ms); validates robustness against inrush or load-dump events |
| TJ max. | +185 °C - enables use in under-hood automotive environments and high-power industrial enclosures without derating penalties |
| Polarity | Unidirectional - suitable only for DC-biased circuits where reverse conduction must be blocked during normal operation |

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 (49.9 V), but lower PPPM (400 W same), smaller SMA package (lower thermal mass, reduced surge margin at high TA) | Not AEC-Q101 qualified; unsuitable for automotive under-hood use; preferred for space-constrained consumer PCBs | Select SMAJ33A only if board space is critical and automotive qualification is not required. |
| SMCJ33A | Higher PPPM (1500 W), same VWM/VBR, larger SMC package; clamping voltage 53.3 V at 28.3 A | Better surge margin for heavy industrial environments (e.g., factory floor motor controls); requires more PCB area | Choose SMCJ33A when system-level surge testing exceeds IEC 61000-4-5 Level 4 (4 kV line-to-ground). |

FAQ
What is the maximum clamping voltage of the TMPG06-33AHE3/53 under standard test conditions?
The TMPG06-33AHE3/53 has a maximum clamping voltage (VC) of 45.7 V when subjected to its rated peak pulse current (IPPM) of 8.8 A using the 10/1000 µs waveform. This value is measured per Figure 3 in the Vishay datasheet 88404 and represents the upper bound of voltage seen by protected circuitry during transient events. The TMPG06-33AHE3/53 maintains this clamping performance across its full operating temperature range.
Is the TMPG06-33AHE3/53 suitable for automotive applications?
Yes, the TMPG06-33AHE3/53 is AEC-Q101 qualified and explicitly designed for automotive use, including engine control, body electronics, and ADAS sensor interfaces. Its 185 °C maximum junction temperature, JESD 201 Class 2 whisker resistance, and RoHS-compliant construction meet stringent automotive reliability requirements. The TMPG06-33AHE3/53 is referenced in Vishay's automotive-grade product documentation and tested per AEC-Q101 stress conditions.
What does the "HE3/53" suffix indicate in TMPG06-33AHE3/53?
The "HE3" suffix denotes RoHS-compliant, matte tin-plated leads meeting JESD 201 Class 2 whisker resistance, while "/53" specifies tape-and-reel packaging in 5500-unit reels on 13-inch diameter cores. This packaging format ensures compatibility with automated pick-and-place systems and supports high-volume manufacturing. The TMPG06-33AHE3/53 is supplied in this configuration per Vishay's ordering information table in document 88404.
How does the TMPG06-33AHE3/53 compare to bidirectional TVS diodes?
The TMPG06-33AHE3/53 is unidirectional only, meaning it protects against positive transients on DC-biased lines but blocks reverse conduction during normal operation. Unlike bidirectional variants, it cannot suppress negative-going surges on AC or floating lines. Its design prioritizes low leakage and precise VWM holdoff for 24 V and 36 V automotive systems. The TMPG06-33AHE3/53 is not interchangeable with bidirectional parts without circuit redesign.
What is the thermal resistance junction-to-lead (RθJL) for the TMPG06-33AHE3/53?
Vishay does not publish RθJL for the TMPG06-33AHE3/53 in datasheet 88404; instead, thermal performance is characterized via power derating curves (Figure 5) and maximum lead temperature (TL = 75 °C) at which 1.0 W power dissipation is guaranteed. For thermal design, engineers should apply the derating factor shown in Figure 2 and ensure lead temperatures remain ≤75 °C. The TMPG06-33AHE3/53 relies on PCB copper pour and lead length for heat dissipation rather than a defined RθJL metric.
