Product details
Overview
TMPG06-24AHE3_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. It features a 22.8 V to 25.2 V breakdown voltage (VBR), 20.5 V stand-off voltage (VWM), 33.2 V clamping voltage (VC) at 12.0 A peak pulse current, 400 W peak pulse power (10/1000 µs), and AEC-Q101 qualification - deployed to safeguard MOSFETs and sensor signal lines against inductive switching transients.
For engineers reviewing the TMPG06-24AHE3_A/D datasheet, TMPG06-24AHE3_A/D pinout, TMPG06-24AHE3_A/D application, or TMPG06-24AHE3_A/D equivalent, key selection criteria include clamping performance under 10/1000 µs surge, junction temperature derating above 25 °C, unidirectional polarity compatibility with DC-biased rails, and MPG06 package thermal interface requirements for sustained 1.0 W power dissipation.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR, it avalanches to limit transient energy across protected circuit nodes. Its low incremental resistance and sub-nanosecond response time ensure minimal overshoot during fast-rising transients such as load dump or inductive kick.
Designed for high-reliability environments, the device sustains operation from –65 °C to +185 °C junction temperature, with thermal derating applied above 25 °C ambient per Figure 2. The 0.094 %/°C VBR temperature coefficient ensures predictable clamping shift across temperature extremes in automotive under-hood applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 22.8 V / 25.2 V - defines minimum avalanche initiation and maximum guaranteed breakdown threshold at 1.0 mA test current |
| VWM | 20.5 V - maximum continuous reverse working voltage before leakage exceeds 1.0 µA; sets safe DC bias margin |
| VC @ IPPM | 33.2 V - clamped voltage at 12.0 A peak pulse, determining worst-case overvoltage seen by downstream ICs |
| PPPM | 400 W - peak pulse power handling with 10/1000 µs waveform, defining surge energy absorption capability |
| IFSM | 40 A - non-repetitive forward surge rating (8.3 ms half-sine), supporting brief fault-current events |
| TJ max. | +185 °C - maximum junction temperature enabling under-hood placement without external heatsinking |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A | Lower PPPM (400 W same), but higher VC (38.9 V), larger SMA package (vs. MPG06), no AEC-Q101 qualification | Not suitable for automotive under-hood use; limited to commercial/industrial PCBs with less stringent reliability requirements | Select when cost sensitivity outweighs automotive qualification and thermal performance needs |
| TPSMF24A | Same VWM/VBR range, but lower PPPM (200 W), smaller SOD-123FL package, AEC-Q101 qualified | Insufficient for ISO 7637-2 Pulse 5a load-dump; appropriate only for low-energy ESD and coupling transients | Choose for space-constrained consumer electronics where 200 W surge capacity suffices |
Compared with SMAJ24A and TPSMF24A, the TMPG06-24AHE3_A/D delivers superior thermal robustness (185 °C TJ), tighter clamping (33.2 V), and automotive-grade validation - making it the optimal choice for 24 V systems requiring sustained surge immunity and under-hood deployment.

FAQ
What is the clamping voltage of the TMPG06-24AHE3_A/D at its rated peak pulse current?
The TMPG06-24AHE3_A/D has a maximum clamping voltage (VC) of 33.2 V at its rated peak pulse current (IPPM) of 12.0 A, measured using the standard 10/1000 µs waveform. This value is critical for ensuring downstream 24 V-rated components remain within their absolute maximum ratings during surge events. The TMPG06-24AHE3_A/D achieves this clamping performance while maintaining low incremental resistance and fast response, directly supporting design margin in automotive load-dump scenarios.
Is the TMPG06-24AHE3_A/D qualified for automotive applications?
Yes, the TMPG06-24AHE3_A/D is AEC-Q101 qualified, having passed stress tests including high-temperature reverse bias, temperature cycling, and mechanical shock per the AEC-Q101 standard. This qualification confirms its suitability for automotive powertrain, chassis, and body electronics. The TMPG06-24AHE3_A/D also supports extended junction temperature operation up to +185 °C, aligning with under-hood environmental requirements.
What does the "HE3_A/D" suffix indicate in TMPG06-24AHE3_A/D?
The "HE3" suffix denotes RoHS-compliant construction with matte tin-plated leads meeting J-STD-002 solderability and JESD 201 Class 2 whisker resistance. The "_A/D" indicates packaging in 13" paper tape and reel with a base quantity of 5500 units - consistent with Vishay's ordering nomenclature for the MPG06 platform. This marking ensures traceability and process compatibility for automated SMT assembly of the TMPG06-24AHE3_A/D.
How does the TMPG06-24AHE3_A/D compare to bidirectional TVS diodes in 24 V systems?
The TMPG06-24AHE3_A/D is unidirectional and optimized for DC-biased 24 V rails where transients occur only in reverse polarity relative to normal operation - such as load dump or inductive kickback. Unlike bidirectional variants, it avoids unnecessary capacitance and leakage in the forward direction, improving noise immunity and efficiency. For pure AC or dual-polarity signal lines, a bidirectional part would be required, but the TMPG06-24AHE3_A/D delivers superior clamping precision and thermal performance in dedicated 24 V DC protection roles.
What is the maximum operating temperature and thermal derating behavior of the TMPG06-24AHE3_A/D?
The TMPG06-24AHE3_A/D has a maximum junction temperature (TJ) of +185 °C and operates from –65 °C to +185 °C. Its peak pulse power (PPPM) must be derated linearly above 25 °C ambient, per Figure 2 in the datasheet - for example, at 125 °C initial junction temperature, PPPM is reduced to ~50 % of 400 W. This derating ensures reliable energy absorption without thermal runaway, a key requirement for the TMPG06-24AHE3_A/D in thermally constrained automotive modules.
