Product details
Overview
TMPG06-30AHE3_A/C from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in automotive and industrial power rails. 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, enabling reliable protection of MOSFETs and sensor signal lines against inductive switching transients.
For engineers reviewing the TMPG06-30AHE3_A/C datasheet, TMPG06-30AHE3_A/C pinout, TMPG06-30AHE3_A/C application, or TMPG06-30AHE3_A/C equivalent, key selection criteria include its AEC-Q101 qualification, 185 °C maximum junction temperature, low 0.097 %/°C VBR temperature coefficient, 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 reverse voltage exceeds its breakdown threshold. Its low incremental resistance and fast response time ensure effective suppression of transient energy without significant voltage overshoot during 10/1000 µs surges.
Rated for 40 A non-repetitive forward surge current (8.3 ms half-sine), it withstands repetitive transients at 0.01 % duty cycle while maintaining stable clamping performance across -65 °C to +185 °C operating junction temperature range. The device's unidirectional polarity and cathode band marking simplify board-level orientation and system-level integration.

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 | Lower PPPM (400 W same), but higher VWM (28.2 V), larger VC (53.3 V), SMA package (smaller footprint, lower thermal mass) | Less suitable for 24 V systems requiring tight clamping; better for 33 V rails or space-constrained designs | Select SMAJ33A only if board layout prioritizes size over clamping voltage margin and thermal robustness. |
| SMCJ33A | Same VBR/VWM range, higher PPPM (1500 W), larger SMC package, higher IPPM (38.4 A), identical AEC-Q101 qualification | Better for high-energy transients (e.g., ISO 16750-2 long-duration pulses); requires larger PCB area and thermal relief | Choose SMCJ33A when system-level testing reveals insufficient margin with 400 W rating or when higher surge repetition is expected. |
Compared with SMAJ33A and SMCJ33A, TMPG06-30AHE3_A/C delivers optimal balance of clamping performance (41.4 V), thermal resilience (185 °C), and AEC-Q101 reliability in the compact MPG06 form factor-making it preferred for cost-sensitive, thermally demanding 24 V automotive modules where strict voltage limiting is critical.

FAQ
What is the maximum operating temperature for TMPG06-30AHE3_A/C?
The TMPG06-30AHE3_A/C has a maximum junction temperature (TJ) of +185 °C, verified per AEC-Q101 stress testing. This allows uninterrupted operation in under-hood automotive locations and sealed industrial enclosures where ambient temperatures exceed 125 °C. Derating begins above 25 °C ambient per Figure 2 in the datasheet, and the device maintains full 400 W pulse capability up to TJ = 125 °C.
Is TMPG06-30AHE3_A/C compatible with lead-free reflow soldering?
Yes, TMPG06-30AHE3_A/C is fully compatible with lead-free reflow processes. Its matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability standards, and the package is rated for solder dip at 275 °C for up to 10 seconds per JESD 22-B106. No pre-baking is required, and the device passes JESD 201 Class 2 whisker testing.
What does the "HE3_A/C" suffix mean in TMPG06-30AHE3_A/C?
The "HE3" suffix indicates RoHS-compliant construction and AEC-Q101 qualification, with "A" denoting the revision code and "/C" specifying the preferred packaging format: 13-inch paper tape and reel, 5500 units per reel. The "HE3" designation also confirms compliance with JESD 201 Class 2 whisker resistance, critical for long-term reliability in vibration-prone automotive applications.
How does TMPG06-30AHE3_A/C compare to bidirectional TVS diodes?
TMPG06-30AHE3_A/C is unidirectional only, optimized for DC power rail protection where polarity is fixed (e.g., 24 V battery feeds). Unlike bidirectional variants, it offers lower leakage (<1 µA at VWM) and tighter VBR tolerance-critical for precision voltage margining. Bidirectional versions (e.g., TMPG06-30AE3) would be required only for AC-coupled or polarity-agnostic signal lines.
Can TMPG06-30AHE3_A/C be used in place of a standard rectifier diode for flyback protection?
No-TMPG06-30AHE3_A/C is not intended as a replacement for general-purpose rectifiers. While it conducts forward current up to 40 A (8.3 ms surge), its VF is 3.5 V at 25 A (vs. ~0.7–1.1 V for Schottky/standard rectifiers), causing excessive power loss in steady-state conduction. It functions exclusively as a transient clamp, not a continuous conduction path.
