Product details
Overview
TMPG06-43AHE3/73 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 400 W peak pulse power rating (10/1000 µs), 40.9–45.2 V breakdown voltage (VBR), 36.8 V maximum working voltage (VWM), 59.3 V clamping voltage at 6.7 A peak pulse current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the TMPG06-43AHE3/73 datasheet, TMPG06-43AHE3/73 pinout, TMPG06-43AHE3/73 application, or TMPG06-43AHE3/73 equivalent, this device is selected for high-temperature stability (TJ up to +185 °C), low incremental resistance, fast response time, and compatibility with automated SMT assembly using matte tin-plated leads compliant with J-STD-002.
Technical Context
The TMPG06-43AHE3/73 operates as a clamping-type unidirectional TVS diode, leveraging an avalanche breakdown mechanism to limit transient voltages above its VBR threshold. Its 10/1000 µs waveform rating reflects standardized surge immunity testing per IEC 61000-4-5 and R.E.A. definitions, with derating applied above TA = 25 °C per Fig. 2 of the datasheet.
It is housed in the MPG06 package - a molded epoxy case with UL 94 V-0 flammability rating, color-banded cathode identification, and lead finish qualified to JESD 201 Class 2 whisker test. The device supports repetitive surge duty cycles up to 0.01 % and withstands solder dip at 275 °C for 10 s per JESD 22-B106.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 40.9 V to 45.2 V - defines precise avalanche onset range for reliable clamping initiation at system-level transients |
| VWM | 36.8 V - maximum continuous DC or RMS operating voltage before leakage exceeds 1 µA |
| VC @ IPPM | 59.3 V - clamped voltage seen by protected circuit during 6.7 A 10/1000 µs surge |
| PPPM | 400 W - peak transient power handling capability under standardized surge waveform |
| IFSM | 40 A - non-repetitive forward surge current tolerance for inductive load switching events |
| TJ max. | +185 °C - enables operation in under-hood automotive environments and high-power industrial enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ43A | Same VBR range (40.9–45.2 V), but SMA package (surface-mount); lower PPPM = 400 W same, but lower IFSM = 30 A | Preferred for space-constrained PCBs; not suitable for through-hole or high-current freewheeling | Select SMAJ43A when board area is limited and leaded mounting is not required. |
| SMCJ43A | Higher PPPM = 1500 W, same VBR, larger SMC package; IFSM = 100 A; no AEC-Q101 qualification | Better for extreme surge environments (e.g., industrial mains input), but lacks automotive qualification | Choose SMCJ43A where higher surge margin is needed and AEC-Q101 is not mandated. |
Compared with SMAJ43A and SMCJ43A, the TMPG06-43AHE3/73 uniquely combines AEC-Q101 qualification, axial-leaded MPG06 packaging for mechanical robustness and high-current freewheeling, and optimized clamping performance for 24–48 V automotive and industrial systems - making it the preferred choice where reliability, thermal endurance, and through-hole serviceability are critical.

FAQ
What is the clamping voltage of the TMPG06-43AHE3/73 at its rated peak pulse current?
The TMPG06-43AHE3/73 has a maximum clamping voltage (VC) of 59.3 V at its specified peak pulse current (IPPM) of 6.7 A under a 10/1000 µs waveform. This value is measured per Figure 3 in the Vishay datasheet 88404 and ensures downstream components see controlled overvoltage during transient events. The clamping behavior is consistent across the full operating temperature range and forms the basis for system-level surge protection design using the TMPG06-43AHE3/73.
Is the TMPG06-43AHE3/73 suitable for automotive applications?
Yes, the TMPG06-43AHE3/73 is AEC-Q101 qualified, meaning it has passed rigorous stress tests for automotive use including temperature cycling, humidity bias, and high-temperature reverse bias. Its +185 °C maximum junction temperature, robust lead finish, and validated surge performance make it appropriate for engine control modules, body control units, and ADAS sensor interfaces. The TMPG06-43AHE3/73 meets requirements for under-hood and chassis-mounted applications where reliability under thermal and electrical stress is essential.
What does the "HE3/73" suffix indicate in TMPG06-43AHE3/73?
The "HE3" suffix denotes RoHS-compliant, matte tin-plated leads qualified to JESD 201 Class 2 for whisker resistance, while "/73" specifies tape-and-reel packaging in 13-inch reels with 5500 units per reel - consistent with Vishay's ordering code convention for the MPG06 family. This packaging format supports automated SMT placement and ensures traceable, moisture-sensitive handling per J-STD-020. The full designation TMPG06-43AHE3/73 thus identifies both material compliance and logistics configuration for the TMPG06-43AHE3/73 device.
How does the TMPG06-43AHE3/73 compare to bidirectional TVS diodes?
The TMPG06-43AHE3/73 is unidirectional only, protecting against positive transients relative to ground - ideal for DC power rails and single-polarity signal lines. Unlike bidirectional variants, it offers lower leakage (<1 µA at VWM) and tighter VBR tolerance, improving efficiency in always-on systems. Bidirectional alternatives would be inappropriate for the TMPG06-43AHE3/73's intended use cases unless AC-coupled or dual-rail protection is required, which is not supported by the TMPG06-43AHE3/73's construction or specification.
Can the TMPG06-43AHE3/73 be used in parallel for higher surge current handling?
No - the TMPG06-43AHE3/73 is not characterized or recommended for parallel operation due to mismatch in VBR tolerances (±5 %) and dynamic impedance, which can cause current imbalance and premature failure of one device. For higher surge ratings, Vishay specifies discrete higher-power alternatives like the SMCJ43A rather than paralleling TMPG06-43AHE3/73 units. System-level surge protection should be designed using a single appropriately rated device, verified per IEC 61000-4-5 test waveforms for the TMPG06-43AHE3/73.
