Product details
Overview
TMPG06-30AHE3_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 and signal lines. It features a 28.5 V to 31.5 V breakdown voltage (VBR), 25.6 V stand-off voltage (VWM), 400 W peak pulse power (10/1000 µs), 9.7 A peak pulse current (IPPM), and clamps to ≤41.4 V at rated surge - deployed on engine control units, sensor interfaces, and 12 V/24 V DC systems.
For engineers reviewing the TMPG06-30AHE3_A/D datasheet, TMPG06-30AHE3_A/D pinout, TMPG06-30AHE3_A/D application, or TMPG06-30AHE3_A/D equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C max junction temperature, low 0.097 %/°C VBR temperature coefficient, 1.0 µA reverse leakage at VWM, 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 transient voltage exceeds its breakdown threshold. Its low incremental resistance and fast response time ensure effective suppression of inductive switching spikes and ESD events without disrupting normal operation under 25.6 V DC bias.
The device is rated for repetitive 10/1000 µs surges at 0.01 % duty cycle and non-repetitive 8.3 ms half-sine surges up to 40 A (IFSM). Thermal derating follows a defined curve above 25 °C ambient, maintaining 1.0 W power dissipation at lead temperature (TL) = 75 °C on an infinite heatsink.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 28.5 V / 31.5 V - defines precise clamping activation window; ensures reliable turn-on before downstream IC damage |
| VWM | 25.6 V - maximum continuous working voltage; allows safe operation across 24 V automotive systems with margin |
| IPPM (10/1000 µs) | 9.7 A - peak surge current handling; supports IEC 61000-4-5 Level 3 (1 kV/2 Ω) transient immunity |
| VC @ IPPM | ≤41.4 V - clamped voltage during full-rated surge; guarantees protected ICs stay below 45 V absolute max rating |
| PPPM | 400 W - peak pulse power capability; enables single-device protection against load dump and inductive kick |
| TJ max | +185 °C - extended junction temperature rating; supports under-hood automotive placement without derating |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Low leakage at VWM | 1.0 µA max at 25.6 V and 25 °C - minimizes standby power loss in always-on vehicle modules |
| Robust surge handling | Withstands 40 A non-repetitive 8.3 ms surge (IEC 61000-4-5 compliant) without parametric shift |
| Lead finish & reliability | Matte tin plating per J-STD-002; passes JESD 201 Class 2 whisker test and JESD 22-B106 solder dip (275 °C/10 s) |
Applications
| Engine Control Unit (ECU) Power Input | Automotive CAN Transceiver Protection |
|---|---|
|
Use Scenario: Protects 12 V supply input of engine control units against ISO 7637-2 Pulse 1 (inductive switch-off) and Pulse 3a/b (load dump). IC Role / Device Role: Primary clamping TVS placed directly at connector entry point before DC/DC converter input. Use Value: Limits transients to ≤41.4 V, preventing latch-up or permanent damage to 40 V-rated buck controllers and microcontrollers. |
Use Scenario: Shields high-speed CAN FD transceivers (e.g., TJA1044) from ESD and bus faults in body control modules. IC Role / Device Role: Bidirectional protection not applicable; this unidirectional device used on VCC rail only, paired with dedicated data-line TVS. Use Value: Maintains <1 µA leakage at 5 V nominal, avoiding signal integrity degradation while surviving ±8 kV contact ESD per IEC 61000-4-2. |
| Industrial PLC Digital Input Module | 48 V Telecom Power Interface |
|
Use Scenario: Guards optocoupler-based digital inputs against field-wiring transients in factory automation cabinets. IC Role / Device Role: Standoff-rated TVS on 24 V input rail, sized to clamp 1 kV/42 Ω surges (IEC 61000-4-5 Level 3). Use Value: Delivers 400 W pulse power handling without derating at 70 °C ambient, enabling compact board layout. |
Use Scenario: Provides secondary overvoltage protection on -48 V telecom rectifier outputs after primary crowbar circuitry. IC Role / Device Role: Unidirectional clamp referenced to system ground, absorbing positive-going surges on negative rail. Use Value: 185 °C max junction temperature supports operation in sealed, convection-limited telecom 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 |
|---|---|---|---|
| SMAJ30A | Same VWM (25.6 V) and VC (48.4 V), but lower PPPM (400 W same), smaller SMA package (lower thermal mass) | Not AEC-Q101 qualified; limited to commercial/industrial use; less suitable for under-hood automotive | Select when cost sensitivity outweighs automotive qualification and thermal performance requirements |
| TPSMF30A | Same VBR range and AEC-Q101 qualification, but SOD-123FL package (smaller footprint, lower IPPM = 8.5 A) | Lower surge current rating reduces margin for ISO 7637-2 Pulse 5a (load dump); requires careful layout for thermal relief | Choose for space-constrained PCBs where 400 W pulse power is sufficient but 9.7 A IPPM margin is acceptable |
Compared with SMAJ30A and TPSMF30A, TMPG06-30AHE3_A/D delivers superior thermal robustness via its larger MPG06 case, maintains AEC-Q101 compliance without trade-offs in clamping voltage, and provides verified 9.7 A surge headroom critical for automotive load-dump immunity.

FAQ
What is the maximum clamping voltage of the TMPG06-30AHE3_A/D at its rated peak pulse current?
The TMPG06-30AHE3_A/D has a maximum clamping voltage (VC) of 41.4 V when subjected to its rated 9.7 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and ensures protected downstream ICs remain within safe voltage limits during surge events. The TMPG06-30AHE3_A/D achieves this with low dynamic impedance and tight parameter distribution.
Is the TMPG06-30AHE3_A/D suitable for protecting 24 V automotive systems?
Yes, the TMPG06-30AHE3_A/D is explicitly designed for 24 V automotive systems. Its 25.6 V stand-off voltage (VWM) provides adequate margin above nominal 24 V rails, while its 28.5–31.5 V breakdown range ensures reliable activation before damage occurs. Fully AEC-Q101 qualified and rated to +185 °C, the TMPG06-30AHE3_A/D meets ISO 7637-2 and IEC 61000-4-5 requirements for under-hood deployment.
Does the TMPG06-30AHE3_A/D have bidirectional polarity?
No, the TMPG06-30AHE3_A/D is unidirectional only, as confirmed in the Vishay datasheet. It protects against positive-going transients on the cathode-connected rail and conducts only in reverse breakdown. For bidirectional protection (e.g., AC lines or data buses), two devices or a dedicated bidirectional TVS such as SMBJ30CA would be required. The cathode is marked by a color band on the MPG06 package.
What is the junction-to-lead thermal resistance (RθJL) of the TMPG06-30AHE3_A/D?
The Vishay datasheet does not specify RθJL for the TMPG06-30AHE3_A/D. Instead, it provides derating curves for peak pulse power versus initial junction temperature and defines 1.0 W steady-state power dissipation at TL = 75 °C on an infinite heatsink. Thermal design should follow the provided power derating graph (Fig. 5) and assume direct lead-to-PCB copper thermal conduction. The TMPG06-30AHE3_A/D relies on lead-frame mass and PCB copper area-not internal thermal resistance specs-for heat dissipation.
Can the TMPG06-30AHE3_A/D replace the SMPG30A in an existing design?
The TMPG06-30AHE3_A/D is not a direct replacement for SMPG30A due to differences in package dimensions and thermal profile: TMPG06 uses a longer body (3.18 mm vs. 2.79 mm) and different lead form. While both share the same electrical ratings and AEC-Q101 qualification, PCB layout changes are required. The TMPG06-30AHE3_A/D offers improved thermal mass and higher surge robustness, but revalidation of mechanical fit and thermal performance is necessary before substitution.
