Product details
Overview
TMPG06-30AHE3_A/B from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in MPG06 package, designed for clamping inductive-switching transients and lightning-induced surges on power and signal lines. It delivers 400 W peak pulse power (10/1000 µs), has a breakdown voltage of 28.5–31.5 V at 1 mA, clamps to ≤41.4 V at 9.7 A, and operates from –65 °C to +185 °C with AEC-Q101 qualification for automotive electronics protection.
For engineers reviewing the TMPG06-30AHE3_A/B datasheet, TMPG06-30AHE3_A/B pinout, TMPG06-30AHE3_A/B application, or TMPG06-30AHE3_A/B equivalent, key selection criteria include unidirectional clamping capability, 25.6 V stand-off voltage, low incremental resistance, fast response time, and compatibility with high-reliability automotive and industrial PCB layouts requiring RoHS-compliant, whisker-tested leads.
Technical Context
This TVS diode uses a passivated silicon junction in molded epoxy (MPG06 case) to achieve stable clamping under repetitive surge conditions. Its 10/1000 µs waveform rating reflects standardized IEC 61000-4-5 surge immunity testing requirements, and its 0.01 % duty cycle limit ensures thermal stability during transient events.
The device exhibits low dynamic impedance (incremental resistance) and a temperature coefficient of VBR of +0.097 %/°C, enabling predictable voltage clamping across wide operating temperatures. Its 3.5 V maximum forward voltage at 25 A supports robust forward conduction during bidirectional surge scenarios when used with external circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 µs) | 400 W - sustains single or low-duty-cycle surges per IEC 61000-4-5 without degradation |
| Breakdown Voltage VBR | 28.5–31.5 V at 1 mA - defines minimum clamping onset threshold under controlled test conditions |
| Stand-off Voltage VWM | 25.6 V - maximum continuous reverse voltage before significant leakage; sets system operating margin |
| Clamping Voltage VC | ≤41.4 V at 9.7 A - actual voltage seen by protected IC/MOSFET during worst-case transient |
| Peak Pulse Current IPPM | 9.7 A (10/1000 µs) - quantifies surge current handling capacity before clamping limits are exceeded |
| Junction Temperature Range | –65 °C to +185 °C - enables deployment in under-hood automotive, industrial motor drives, and power supply rails |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress |
Pinout & Package
Package: MPG06 - molded epoxy case with matte tin-plated leads, UL 94 V-0 rated, 0.115–0.125 inch lead length, 0.023–0.026 inch lead diameter, RoHS-compliant and JESD 201 Class 2 whisker tested. Cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / transient return path | Connected to lower-potential side (e.g., ground or return rail); completes clamping loop during reverse surge |
| Cathode | Reverse-biased clamping node | Connected to protected line (e.g., 24 V rail or sensor output); conducts only when VLINE exceeds VBR |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional polarity | Enables precise clamping on positive-going transients without affecting DC bias on protected lines |
| 400 W peak pulse power (10/1000 µs) | Meets IEC 61000-4-5 Level 4 surge immunity requirements for industrial and automotive subsystems |

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 30 V nominal VBR, but SMA package (smaller footprint, lower IPPM = 6.8 A, PPPM = 400 W) | Limited to lower-energy surges; not AEC-Q101 qualified; unsuitable for under-hood automotive use | Select when board space is constrained and automotive qualification is not required |
| SMCJ30A | Higher IPPM = 13.9 A and same VC = 48.4 V, but larger SMC package and no AEC-Q101 certification | Better energy handling than TMPG06-30AHE3_A/B, but lacks automotive reliability validation and lead finish compliance | Prefer for industrial power supplies where higher surge margin is needed and whisker resistance is not mandated |
Compared with SMAJ30A and SMCJ30A, TMPG06-30AHE3_A/B provides AEC-Q101 qualification, JESD 201 Class 2 whisker resistance, and optimized lead geometry for automated assembly-making it the only choice for automotive Tier-1 production where process reliability and long-term field stability are mandatory.

FAQ
What is the maximum clamping voltage of the TMPG06-30AHE3_A/B under standard test conditions?
The TMPG06-30AHE3_A/B has a maximum clamping voltage (VC) of 41.4 V when subjected to a 10/1000 µs surge current of 9.7 A at TA = 25 °C. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during worst-case transient events. The TMPG06-30AHE3_A/B maintains this clamping performance across its full operating temperature range due to its low dynamic impedance and stable junction design.
Is the TMPG06-30AHE3_A/B suitable for automotive applications?
Yes, the TMPG06-30AHE3_A/B is AEC-Q101 qualified and specifically designed for automotive use, including body control modules, lighting drivers, and infotainment power rails. Its 185 °C maximum junction temperature, matte tin-plated leads compliant with JESD 201 Class 2 whisker testing, and RoHS-compliant construction meet Tier-1 OEM requirements. The TMPG06-30AHE3_A/B has undergone rigorous stress testing including HTGB, H3TRB, and temperature cycling per AEC-Q101 Rev D.
What does the "HE3_A/B" suffix indicate in TMPG06-30AHE3_A/B?
The "HE3" suffix denotes Vishay's high-reliability, RoHS-compliant construction with matte tin-plated leads that pass JESD 201 Class 2 whisker testing. The "_A/B" indicates revision level-'A' and 'B' are successive manufacturing revisions reflecting minor process improvements or material updates, both fully interchangeable and meeting identical electrical and mechanical specifications. The TMPG06-30AHE3_A/B is supplied in 13" paper tape and reel packaging with 5500 units per reel.
How does the TMPG06-30AHE3_A/B compare to bidirectional TVS diodes?
The TMPG06-30AHE3_A/B is unidirectional only, meaning it clamps positive transients on the cathode-connected line while blocking reverse voltage up to 25.6 V. Unlike bidirectional variants, it cannot suppress negative-going surges without external circuitry. This makes the TMPG06-30AHE3_A/B ideal for DC power rail protection where polarity is fixed and leakage current must be minimized-its <1 μA leakage at VWM improves efficiency in always-on systems compared to bidirectional equivalents.
What is the thermal derating behavior of the TMPG06-30AHE3_A/B above 25 °C ambient?
The TMPG06-30AHE3_A/B follows a linear derating curve from 100 % power at TA = 25 °C down to 0 % at TA = 175 °C, per Figure 2 in the datasheet. At 75 °C ambient, its peak pulse power remains at 75 % of 400 W (i.e., 300 W), and its steady-state power dissipation (PD) is limited to 1.0 W on an infinite heatsink at TL = 75 °C. The TMPG06-30AHE3_A/B's 185 °C TJmax allows operation in high-temperature enclosures where other TVS devices would thermally throttle.
