Product details
Overview
TMPG06-33AHE3/54 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 on engine control units, sensor interfaces, and 12 V/24 V DC systems.
For engineers reviewing the TMPG06-33AHE3/54 datasheet, TMPG06-33AHE3/54 pinout, TMPG06-33AHE3/54 application, or TMPG06-33AHE3/54 equivalent, key selection criteria include AEC-Q101 qualification, high-temperature junction rating (TJ = 185 °C), low incremental resistance, fast response time, and compatibility with lead-free reflow and solder-dip processes per JESD 22-B106.
Technical Context
The TMPG06-33AHE3/54 operates as a silicon avalanche diode with unidirectional polarity, leveraging controlled reverse-biased breakdown to clamp transient surges before downstream ICs or MOSFETs are damaged. Its 10/1000 µs waveform rating reflects standardized lightning and inductive-switching surge immunity testing per IEC 61000-4-5 and ISO 7637-2.
Thermal performance is defined by a 1.0 W steady-state power dissipation (PD) on infinite heatsink at TL = 75 °C and full derating above TA = 25 °C per Figure 2. The device maintains stable VBR across temperature with a +0.098 %/°C coefficient and supports repetitive surge duty cycles up to 0.01 %.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 31.4 V / 34.7 V - defines reliable turn-on threshold under surge conditions; ensures clamping initiates before protected circuit exceeds safe voltage limits. |
| VWM | 28.2 V - maximum continuous reverse operating voltage; allows normal system operation without leakage-induced power loss or false triggering. |
| IPPM (10/1000 µs) | 8.8 A - peak surge current handling capacity; sustains single-event transients typical of automotive load dump or relay coil flyback. |
| VC @ IPPM | ≤45.7 V - clamped voltage during rated surge; determines maximum stress imposed on downstream components during protection event. |
| PPPM | 400 W - peak pulse power capability; enables compliance with ISO 16750-2 and SAE J1113-11 surge test levels for 12 V systems. |
| TJ max. | +185 °C - maximum junction temperature; supports under-hood automotive placement and long-term reliability in high-ambient environments. |
| AEC-Q101 | Qualified - certified for automotive-grade reliability including HTOL, TC, UHAST, and ESD testing per AEC standard. |
Pinout & Package
Package: MPG06 - molded epoxy case with matte tin-plated leads, UL 94 V-0 rated, 0.100" (2.54 mm) lead pitch, 0.125" (3.18 mm) body length, cathode indicated by color band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction path / surge return path | Connected to ground or low-impedance return plane; carries full surge current during clamping event. |
| Cathode | Protected line connection / high-side terminal | Connected to line being protected (e.g., battery rail or sensor supply); reverse-biased during normal operation. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 µs) | Enables robust protection against ISO 7637-2 Pulse 1, 2a, 3a/b, and SAE J1113-11 Class III/IV transients without derating. |
| AEC-Q101 qualification | Validates suitability for automotive powertrain, body electronics, and ADAS modules requiring zero-defect reliability over 15+ year service life. |
| 185 °C maximum junction temperature | Supports direct mounting near high-heat sources (e.g., ignition coils, motor drivers) without thermal shutdown or parameter drift. |
| Low incremental resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns rise time), improving protection margin for sensitive CMOS inputs. |
| Matte tin plating, J-STD-002 compliant | Ensures reliable solder wetting and intermetallic formation in both wave and reflow assembly, reducing voiding and cold-joint risk. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|

Use Value: 40 A IFSM rating handles repeated 8.3 ms half-sine surges from motor startup/stall events without degradation. |
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 | Same VWM (28.2 V) and VC (48.4 V), but lower PPPM (400 W same), smaller SMA package (lower thermal mass), no AEC-Q101 qualification. | Not qualified for automotive under-hood use; suitable for commercial-grade consumer or telecom power supplies. | Select when cost and board space are prioritized over automotive qualification and high-temperature stability. |
| SMCJ33A | Higher PPPM (1500 W), larger SMC package, same VWM/VBR, AEC-Q101 qualified, but higher VC (53.3 V). | Better for severe surge environments (e.g., heavy-duty truck 24 V systems), but clamping voltage may exceed some IC tolerances. | Select when surge energy exceeds 400 W requirements and layout allows larger footprint; verify downstream voltage margin. |
Compared with SMAJ33A and SMCJ33A, the TMPG06-33AHE3/54 delivers optimal balance of AEC-Q101 compliance, 185 °C junction rating, and precise 45.7 V clamping - making it preferred for space-constrained automotive modules where thermal headroom and voltage margin are critical.

FAQ
What is the maximum clamping voltage of the TMPG06-33AHE3/54 during a 10/1000 µs surge?
The TMPG06-33AHE3/54 has a maximum clamping voltage (VC) of 45.7 V when subjected to its rated peak pulse current of 8.8 A (10/1000 µs waveform). This value is measured per JEDEC standards and guarantees that downstream components experience no more than 45.7 V during a defined transient event. The TMPG06-33AHE3/54 achieves this while maintaining low incremental resistance and fast response, making it suitable for protecting sensitive 3.3 V or 5 V logic interfaces fed from 24 V rails via regulators.
Is the TMPG06-33AHE3/54 qualified for automotive applications?
Yes, the TMPG06-33AHE3/54 is AEC-Q101 qualified, having passed stress tests including high-temperature operating life (HTOL), temperature cycling (TC), unbiased highly accelerated stress test (UHAST), and ESD (HBM/MM). Its 185 °C maximum junction temperature and construction per JESD201 Class 2 whisker testing confirm suitability for under-hood automotive modules such as body control units and ADAS sensors. The TMPG06-33AHE3/54 meets the reliability and traceability requirements mandated for Tier 1 automotive supply chains.
What does the "HE3/54" suffix indicate in TMPG06-33AHE3/54?
The "HE3" suffix denotes RoHS-compliant, matte tin-plated leads meeting J-STD-002 solderability and JESD22-B102 intermetallic growth requirements, plus JESD201 Class 2 whisker resistance. The "/54" indicates tape-and-reel packaging per Vishay's standard 13-inch reel with 5500 units - compatible with automated SMT placement equipment. The TMPG06-33AHE3/54 uses the MPG06 case, distinct from SMA or SMC packages, offering optimized thermal performance in compact form factor.
Can the TMPG06-33AHE3/54 be used in bidirectional configurations?
No, the TMPG06-33AHE3/54 is unidirectional only, as explicitly stated in the Vishay datasheet. It conducts in forward bias like a standard diode and clamps only in reverse breakdown. For bidirectional transient suppression (e.g., AC lines or data buses), a separate symmetric TVS array or dedicated bidirectional part such as SMBJ33CA is required. Using two TMPG06-33AHE3/54 devices in series opposition is not recommended due to mismatched VBR tolerance and lack of characterization for that configuration.
What is the leakage current specification for TMPG06-33AHE3/54 at its stand-off voltage?
At the stand-off voltage (VWM) of 28.2 V and ambient temperature of 25 °C, the TMPG06-33AHE3/54 exhibits a maximum reverse leakage current (ID) of 1.0 µA. At elevated temperature (TJ = 150 °C), leakage rises to ≤5.0 µA - still well below thresholds that would affect power budget or signal integrity in most 12 V or 24 V systems. This low leakage ensures minimal standby power loss and avoids false triggering in high-impedance sensor or communication circuits.
