Product details
Overview
TMPG06-24HE3/73 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 22.8 V to 25.2 V breakdown voltage (VBR), 20.5 V maximum working voltage (VWM), 400 W peak pulse power (10/1000 µs), 12.0 A peak pulse current (IPPM), and clamps to ≤33.2 V at rated surge - deployed on engine control units, sensor interfaces, and 12 V/24 V DC systems.
For engineers reviewing the TMPG06-24HE3/73 datasheet, TMPG06-24HE3/73 pinout, TMPG06-24HE3/73 application, or TMPG06-24HE3/73 equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C max junction temperature, low incremental resistance, fast response time, and MPG06 package compatibility with high-reliability automotive PCB layouts.
Technical Context
This TVS diode operates as a clamping device in parallel with protected circuitry, activating when reverse voltage exceeds VWM (20.5 V) and entering avalanche breakdown above VBR (min 22.8 V). Its low clamping ratio (VC/VBR ≈ 1.31) and 0.094 %/°C VBR temperature coefficient ensure stable protection across wide thermal ranges.
Rated for 40 A non-repetitive forward surge (8.3 ms half-sine) and 1.0 W steady-state power dissipation at TL = 75 °C, it supports high-energy transients from inductive switching while maintaining reliability under sustained thermal stress in under-hood environments.
Key Specifications

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 | Same VWM (20.5 V), lower PPPM (400 W same), but SMA package (smaller footprint, lower IPPM = 11.9 A) | Less robust for high-current transients; suitable only where board space is constrained and surge energy is lower | Select SMAJ24A only if layout density outweighs need for margin in high-inductance circuits. |
| SMCJ24A | Same VWM and VBR, higher PPPM (1500 W), larger SMC package, IPPM = 43.4 A | Overqualified for 400 W needs; adds cost and board area without benefit in typical 12 V/24 V rail designs | Choose SMCJ24A only when protecting against extreme transients (e.g., ISO 7637-2 Pulse 5a) requiring >1 kW headroom. |
Compared with SMAJ24A and SMCJ24A, the TMPG06-24HE3/73 delivers optimal balance of AEC-Q101 compliance, 400 W surge capacity, MPG06 mechanical robustness, and thermal resilience - making it the preferred choice for production automotive and industrial 24 V systems where reliability and standardized packaging are critical.

FAQ
What is the maximum clamping voltage of the TMPG06-24HE3/73 at its rated peak pulse current?
The TMPG06-24HE3/73 has a maximum clamping voltage (VC) of 33.2 V when subjected to its rated 12.0 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is guaranteed across production lots and ensures downstream ICs see no more than 33.2 V during surge events. The TMPG06-24HE3/73 achieves this clamping performance while maintaining low incremental resistance and thermal stability up to 185 °C junction temperature.
Is the TMPG06-24HE3/73 qualified for automotive applications?
Yes, the TMPG06-24HE3/73 is explicitly AEC-Q101 qualified per the Vishay datasheet (Document Number: 88404, Revision: 17-Sep-2021). It undergoes rigorous stress testing including temperature cycling, high-temperature reverse bias (HTRB), and ESD verification. This qualification confirms its suitability for use in automotive engine control units, body electronics, and ADAS systems where zero-field-failure reliability is mandatory. The TMPG06-24HE3/73 also meets JESD 201 Class 2 whisker resistance requirements.
What does the "HE3/73" suffix indicate in TMPG06-24HE3/73?
The "HE3" suffix denotes RoHS-compliant, matte tin-plated leads meeting J-STD-002 solderability and JESD 201 Class 2 whisker resistance requirements. The "/73" is a Vishay internal tape-and-reel packaging code indicating 5500 units per 13-inch diameter reel in paper tape. Together, HE3/73 identifies the exact manufacturing and packaging variant of the TMPG06-24HE3/73, ensuring consistency in assembly yield and long-term supply chain traceability.
Can the TMPG06-24HE3/73 be used in bidirectional configurations?
No, the TMPG06-24HE3/73 is specified for unidirectional polarity only, as confirmed in the Vishay datasheet's FEATURES section. Its cathode band marks the terminal that must be connected toward the protected line, with the anode grounded. For bidirectional protection, two TMPG06-24HE3/73 devices would need back-to-back configuration - but Vishay does not characterize or guarantee performance in that arrangement. Use dedicated bidirectional TVS parts (e.g., SMBJ24CA) instead.
What is the thermal derating behavior of the TMPG06-24HE3/73 above 25 °C ambient?
The TMPG06-24HE3/73 follows standard derating per Figure 2 in its datasheet: peak pulse power (PPPM) decreases linearly above TA = 25 °C, reaching ~50 % at TA ≈ 125 °C. Steady-state power dissipation (PD = 1.0 W) is rated at TL = 75 °C and must be further derated per Figure 5. The TMPG06-24HE3/73 maintains full surge capability up to TJ = 185 °C, but PCB layout must ensure adequate thermal conduction to avoid exceeding this limit during repeated surges.
