Product details
Overview
TMPG06-33AHE3/73 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 31.4–34.7 V breakdown voltage (VBR), 28.2 V stand-off voltage (VWM), 400 W peak pulse power (10/1000 µs), 8.8 A peak pulse current (IPPM), and clamps to ≤45.7 V at rated surge - deployed to safeguard MOSFETs, sensor interfaces, and microcontroller I/O against inductive switching transients.
For engineers reviewing the TMPG06-33AHE3/73 datasheet, TMPG06-33AHE3/73 pinout, TMPG06-33AHE3/73 application, or TMPG06-33AHE3/73 equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C maximum 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, conducting only when reverse voltage exceeds VWM (28.2 V) and entering avalanche breakdown above VBR (min 31.4 V). Its 10/1000 µs waveform rating reflects standardized surge immunity testing per REA and ANSI/IEEE C62.35, with thermal derating applied above 25 °C ambient per Figure 2.
The device exhibits low dynamic impedance (evidenced by 45.7 V clamping at 8.8 A), enabling effective voltage limiting during fast transients. Its unidirectional polarity, matte tin-plated leads compliant with J-STD-002, and JESD 201 Class 2 whisker resistance support long-term reliability in vibration-prone automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 31.4 V / 34.7 V - defines precise avalanche onset range for predictable clamping activation |
| VWM | 28.2 V - maximum continuous reverse operating voltage before leakage rises significantly |
| IPPM (10/1000 µs) | 8.8 A - peak surge current it safely shunts without failure under standard lightning/surge test waveform |
| VC @ IPPM | ≤45.7 V - clamped voltage seen by protected IC during full-rated surge, limiting stress on downstream components |
| PPPM | 400 W - peak pulse power handling capacity, critical for absorbing energy from inductive load switching |
| TJ max | +185 °C - enables operation in under-hood automotive zones and high-temperature industrial enclosures |
| AEC-Q101 qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress tests |
Pinout & Package
Package: MPG06 - molded epoxy case with axial leads, UL 94 V-0 rated, 0.100" (2.54 mm) lead spacing, cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., ground or return path) in unidirectional TVS configuration |
| Cathode | Reverse-biased clamping terminal | Connected to protected line (e.g., 24 V rail or sensor output); color band identifies this end |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 µs) | Enables reliable suppression of ISO 7637-2 Pulse 1/2a/5a transients in 12 V/24 V automotive systems |
| AEC-Q101 qualification | Confirms suitability for automotive powertrain, body control, and ADAS modules requiring zero-failure field performance |
| 185 °C maximum junction temperature | Supports placement near heat-generating components (e.g., DC-DC converters, motor drivers) without derating loss |
| Low clamping ratio (VC/VBR ≈ 1.4) | Minimizes overvoltage overshoot during surge events, reducing risk of latch-up or gate oxide damage in protected ICs |
| Matte tin plating & JESD 201 Class 2 | Ensures solder joint integrity and mitigates tin whisker growth in long-life, high-vibration applications |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 24 V supply lines in body control modules from load dump and inductive kickback. IC Role / Device Role / Timing Role: Unidirectional TVS placed across input rail to clamp transients before they reach LDOs and MCU power pins. Use Value: Withstands 400 W surges and maintains VC ≤ 45.7 V, preventing brownout or reset events during alternator load dump. |
Use Scenario: Shielding analog outputs of pressure/temperature sensors in factory automation PLC I/O modules. IC Role / Device Role / Timing Role: Parallel-connected TVS on 4–20 mA or 0–10 V signal lines to absorb ESD and cable discharge events. Use Value: Low leakage (<1 µA at VWM) avoids signal offset error; fast response preserves sensor accuracy during transient exposure. |
| Automotive Lighting Driver Protection | Telecom DC Power Input Protection |
Use Scenario: Safeguarding LED driver ICs in headlamp control units exposed to relay coil flyback and battery reversal. IC Role / Device Role / Timing Role: TVS mounted at driver input to limit reverse voltage and clamp positive spikes during switching transitions. Use Value: 185 °C TJ rating allows direct mounting near high-power LED drivers; AEC-Q101 ensures compliance with UNECE R128. |
Use Scenario: Guarding PoE-powered network switches against surges on 48 V DC input derived from midspan injectors. IC Role / Device Role / Timing Role: Primary overvoltage clamp on DC input stage upstream of DC-DC converters and Ethernet PHYs. Use Value: 400 W PPPM handles multiple repetitive surges per IEC 61000-4-5 Level 3; VWM = 28.2 V provides margin above nominal 48 V × 0.6. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ33A-E3/5BT | Same VWM (28.2 V) and VC (45.7 V), but lower PPPM (400 W vs. SMAJ series' 400 W), identical MPG06 footprint, higher IFSM (40 A vs. 40 A), same AEC-Q101 status | Identical use cases; SMAJ33A-E3/5BT uses slightly different molding compound but shares mechanical and electrical specs | Select TMPG06-33AHE3/73 for traceable Vishay HE3 tape-and-reel logistics and documented high-temp stability per Fig. 2 derating curve |
| 1.5SMC33A | Higher VC (53.3 V), larger SMC package (7.11 × 6.22 mm vs. MPG06's 3.18 × 2.29 mm axial), same VWM, no AEC-Q101 qualification | Suitable for non-automotive industrial power supplies where space and qualification are less constrained | Choose TMPG06-33AHE3/73 when AEC-Q101 compliance, compact axial form factor, or 185 °C operation is mandatory |
Compared with SMAJ33A-E3/5BT and 1.5SMC33A, TMPG06-33AHE3/73 delivers identical clamping performance in a smaller axial package with certified automotive qualification and extended high-temperature capability - making it optimal for space-constrained, thermally demanding vehicle subsystems.

FAQ
What is the breakdown voltage tolerance for TMPG06-33AHE3/73?
The TMPG06-33AHE3/73 has a specified breakdown voltage range of 31.4 V to 34.7 V at 1.0 mA test current (IT), per the Electrical Characteristics table in Vishay Document 88404. This ±5.3% tolerance ensures consistent clamping behavior across production lots while accommodating process variation without compromising protection margins.
Is TMPG06-33AHE3/73 suitable for 24 V automotive systems?
Yes, TMPG06-33AHE3/73 is explicitly designed for 24 V automotive applications. Its 28.2 V stand-off voltage (VWM) provides adequate margin above nominal 24 V (including 10% tolerance and ripple), while its 45.7 V clamping voltage stays well below typical 36 V absolute maximum ratings of protected power management ICs in such systems.
Does TMPG06-33AHE3/73 have a bidirectional variant?
No, TMPG06-33AHE3/73 is unidirectional only, as confirmed in the FEATURES section of the datasheet. Vishay does not offer a bidirectional version in the TMPG06-33A designation; bidirectional TVS variants in this family (e.g., TMPG06-33CA) use distinct part numbering and are not interchangeable with TMPG06-33AHE3/73.
What is the lead finish and solderability specification for TMPG06-33AHE3/73?
TMPG06-33AHE3/73 features matte tin-plated leads compliant with J-STD-002 for solderability and JESD 22-B102 for solder heat resistance. The HE3 suffix confirms it passes JESD 201 Class 2 whisker testing, ensuring long-term reliability in high-humidity and thermal-cycling environments typical of automotive and industrial deployments.
How does TMPG06-33AHE3/73 handle repetitive surge events?
TMPG06-33AHE3/73 supports repetitive surges at a 0.01% duty cycle (e.g., 4 pulses per minute maximum), as defined in the Maximum Ratings table. Its thermal design allows dissipation of residual energy between pulses, provided board layout provides adequate copper area and ambient temperature remains within derated limits per Figure 2.
