Product details
Overview
TMPG06-24AHE3_A/B 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 22.8 V to 25.2 V breakdown voltage (VBR), 20.5 V stand-off voltage (VWM), 400 W peak pulse power (10/1000 µs), 12.0 A peak pulse current (IPPM), and clamps to ≤33.2 V at rated surge, with AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the TMPG06-24AHE3_A/B datasheet, TMPG06-24AHE3_A/B pinout, TMPG06-24AHE3_A/B application, or TMPG06-24AHE3_A/B equivalent, key selection criteria include clamping voltage margin relative to protected IC VCC, thermal derating above 25 °C, unidirectional polarity alignment with DC bias, and compatibility with MPG06 surface-mount footprint and reflow profiles.
Technical Context
This TVS operates as a voltage-clamped shunt protector: when reverse voltage exceeds VBR, it avalanches rapidly (<1 ns response) to divert transient energy away from downstream components. Its low incremental resistance (typ. <0.5 Ω) ensures minimal voltage overshoot during high-current surges like ISO 7637-2 pulse 1/2a/5a.
Designed for high-reliability environments, the device sustains operation up to +185 °C junction temperature, supports 40 A non-repetitive forward surge (8.3 ms half-sine), and maintains stable VBR temperature coefficient (0.094 %/°C) across its operating range - critical for under-hood automotive electronics where thermal drift must be predictable.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 22.8 V / 25.2 V - defines minimum trigger threshold and maximum avalanche onset spread; ensures reliable conduction before protected circuit exceeds absolute max rating |
| VWM | 20.5 V - maximum continuous reverse working voltage; must exceed normal system DC rail or signal swing to prevent leakage-induced power loss |
| IPPM (10/1000 µs) | 12.0 A - peak surge current handling capacity; determines survivability against standardized load-dump or ESD-like transients |
| VC @ IPPM | ≤33.2 V - clamped voltage during full-rated surge; sets upper bound on stress seen by downstream MOSFET gate or MCU I/O |
| PPPM | 400 W - peak pulse power dissipation capability; validates suitability for ISO 16750-2 Class III/IV and IEC 61000-4-5 Level 3 tests |
| TJ max | +185 °C - maximum junction temperature; enables placement near hot components (e.g., power converters) without thermal shutdown risk |
| AEC-Q101 qualified | Yes - certified for automotive electronic modules per stress test requirements including HTGB, HTRB, and temperature cycling |
Pinout & Package
Package: MPG06 - molded epoxy case with matte tin-plated leads, UL 94 V-0 rated, 0.115–0.125 inch (2.92–3.18 mm) body width, 0.023–0.026 inch (0.584–0.66 mm) lead diameter, 1.0 inch (25.4 mm) minimum tape reel length.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry / low-side reference | Connected to ground or lower-potential node; establishes reference for unidirectional clamping action |
| Cathode | Reverse-biased input / surge sink | Connected to protected line (e.g., 24 V rail); conducts avalanche current to anode during overvoltage events |
| Color band | Polarity indicator | White or black band marks cathode end - mandatory for correct orientation during PCB assembly to avoid open-circuit failure |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 µs) | Enables single-device protection against severe automotive load dump (ISO 16750-2) without parallel staging |
| AEC-Q101 qualification | Validates long-term reliability under automotive thermal, humidity, and vibration stress conditions |
| Low clamping voltage (≤33.2 V @ 12 A) | Provides ≥5 V margin below typical 36 V automotive system max, preventing latch-up in 24 V logic interfaces |
| High TJ max (+185 °C) | Supports placement in engine control units (ECUs) and power distribution modules where ambient exceeds 125 °C |
| Matte tin plating & JESD 201 Class 2 whisker resistance | Ensures solder joint integrity and long-term interconnect reliability in high-vibration automotive harnesses |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A | Same VWM (20.5 V) and VC (38.9 V), but lower PPPM (400 W same), smaller SMA package (vs. MPG06), no AEC-Q101 qualification | Not suitable for automotive under-hood use; limited to commercial/industrial ambient ≤125 °C | Select when cost or board space is prioritized over automotive qualification and high-temperature operation |
| TPSMF24A | Higher VC (38.9 V), same VWM, identical AEC-Q101 and +175 °C TJ max, but lower IPPM (9.9 A) and PPPM (200 W) | Insufficient for ISO 16750-2 load dump; better suited for ESD-only (IEC 61000-4-2) or low-energy transients | Select only for secondary protection stages or low-power signal lines where 400 W capability is unnecessary |
Compared with SMAJ24A and TPSMF24A, the TMPG06-24AHE3_A/B uniquely combines AEC-Q101 qualification, +185 °C operation, and full 400 W surge handling in the rugged MPG06 package - making it the only choice for primary 24 V rail protection in demanding automotive and industrial power systems.

FAQ
What is the maximum operating temperature for TMPG06-24AHE3_A/B?
The TMPG06-24AHE3_A/B has a maximum junction temperature (TJ) of +185 °C, enabling reliable operation in under-hood automotive locations and high-power industrial enclosures. This rating is validated per AEC-Q101 stress testing and allows for direct mounting near heat-generating components without thermal derating penalties up to this limit. The TMPG06-24AHE3_A/B maintains specified VBR and clamping performance across its full -65 °C to +185 °C operating range.
Is TMPG06-24AHE3_A/B suitable for protecting 24 V automotive power supplies?
Yes - the TMPG06-24AHE3_A/B is explicitly qualified for automotive use (AEC-Q101) and designed for 24 V system protection. With VWM = 20.5 V, it safely withstands nominal 24 V rail fluctuations while triggering reliably during load dump events. Its 400 W peak pulse power and 33.2 V clamping voltage provide sufficient margin below typical 36 V automotive absolute maximum ratings, making TMPG06-24AHE3_A/B ideal for ECU, ADAS, and body control module power inputs.
What does the "HE3_A/B" suffix indicate in TMPG06-24AHE3_A/B?
The "HE3" suffix denotes RoHS-compliant construction with matte tin-plated leads that meet JESD 201 Class 2 whisker resistance requirements, while "A/B" indicates the revision code per Vishay's ordering nomenclature - reflecting minor process or test enhancements documented in revision-controlled datasheets. Both TMPG06-24AHE3_A and TMPG06-24AHE3_B share identical electrical specifications, package dimensions, and AEC-Q101 qualification status; the revision change does not affect form, fit, or function of the TMPG06-24AHE3_A/B device.
How does TMPG06-24AHE3_A/B compare to bidirectional TVS diodes?
The TMPG06-24AHE3_A/B is unidirectional only, meaning it protects against positive transients on a DC-biased line (e.g., 24 V rail to ground). Unlike bidirectional variants, it exhibits low leakage (<1 µA at VWM) and avoids forward conduction during normal operation - critical for power rails where reverse leakage could cause battery drain. Bidirectional alternatives would conduct during both polarities, increasing quiescent current and reducing efficiency in DC systems; TMPG06-24AHE3_A/B is therefore preferred for 24 V automotive and industrial supply protection.
Can TMPG06-24AHE3_A/B be used in parallel for higher surge current handling?
No - the TMPG06-24AHE3_A/B is not characterized or recommended for parallel operation. Due to manufacturing tolerances in VBR (22.8–25.2 V), paralleled units will not share current evenly; the lowest-VBR device will dominate conduction and likely fail prematurely under surge conditions. For higher surge capability, select a single higher-rated device (e.g., TMPG06-27A) or implement staged protection with upstream current-limiting impedance. The TMPG06-24AHE3_A/B is engineered as a standalone 400 W solution.
