Product details
Overview
T6N30AHM3/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® Transient Voltage Suppressor in DFN3820A package, with 30 V nominal breakdown voltage (VBR), 25.6 V stand-off voltage (VWM), 41.4 V maximum clamping voltage at 14.5 A peak pulse current, and 600 W peak pulse power rating (10/1000 μs). It is AEC-Q101 qualified and rated for TJ = 185 °C, designed for automotive sensor signal-line protection.
For engineers reviewing the T6N30AHM3/H datasheet, T6N30AHM3/H pinout, T6N30AHM3/H application, or T6N30AHM3/H equivalent, key selection criteria include unidirectional clamping performance under 10/1000 μs transients, junction temperature derating above 25 °C, side-wettable flank compatibility with AOI, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology optimized for high-temperature stability and low-leakage operation. Its DFN3820A package features matte tin-plated terminals compliant with J-STD-002 and JESD 22-B102, and meets MSL Level 1 with 260 °C reflow peak.
The device delivers 41.4 V clamping voltage at 14.5 A IPPM under 10/1000 μs waveform, with thermal resistance RθJA up to 175 °C/W and RθJM as low as 5 °C/W. It achieves 30 kV ESD immunity per IEC 61000-4-2 (contact and air discharge).
Key Specifications

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 | DO-214AC package; higher RθJA (~190 °C/W); 30 V VWM; 48.4 V VC @ 12.3 A | Larger footprint; less suitable for space-constrained automotive modules | Choose SMAJ30A only if legacy through-hole or larger SMT assembly is required and thermal margin permits |
| SMCJ30A | DO-214AB package; 600 W rating; 48.4 V VC @ 12.3 A; RθJA ~140 °C/W | Higher clamping voltage increases stress on protected ICs; not AEC-Q101 qualified | Select SMCJ30A only for non-automotive industrial use where AEC-Q101 is not mandated |
Compared with SMAJ30A and SMCJ30A, T6N30AHM3/H provides lower clamping voltage (41.4 V vs. ≥48.4 V), superior thermal performance via DFN3820A's low RθJM (5 °C/W), and guaranteed AEC-Q101 qualification-making it the preferred choice for next-generation automotive ECUs requiring compact, high-reliability transient suppression.

FAQ
What is the breakdown voltage tolerance of T6N30AHM3/H?
The T6N30AHM3/H has a ±5 % breakdown voltage tolerance, specified as 28.5 V (min), 30.0 V (nominal), and 31.5 V (max) at 1.0 mA test current. This tight tolerance ensures consistent clamping behavior across production lots and supports precise system-level overvoltage margining in automotive designs.
Is T6N30AHM3/H compatible with lead-free reflow processes?
Yes, T6N30AHM3/H is fully compatible with lead-free reflow processes, meeting J-STD-020 MSL Level 1 with a maximum peak temperature of 260 °C. Its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102, ensuring reliable solderability and whisker resistance per JESD 201 Class 2.
Does T6N30AHM3/H require a heatsink for 600 W pulse handling?
No external heatsink is required for single-pulse 600 W operation, as the DFN3820A package's thermal resistance junction-to-mount (RθJM) is as low as 5 °C/W. However, sustained or repetitive pulses demand proper PCB copper area beneath the anode pad to maintain TJ ≤ 185 °C per JEDEC 51-14 guidelines.
How does the side-wettable flank design benefit T6N30AHM3/H assembly?
The side-wettable flanks on T6N30AHM3/H enable full-surface automatic optical inspection (AOI) of solder joints on all four package edges. This eliminates X-ray inspection needs, reduces post-reflow defect escapes, and improves first-pass yield in high-volume automotive electronics manufacturing.
Can T6N30AHM3/H replace SMAJ30A in existing designs?
T6N30AHM3/H is not a direct pin-compatible replacement for SMAJ30A due to different packages (DFN3820A vs. DO-214AC), but its identical electrical ratings (30 V VBR, 600 W PPPM) and superior clamping (41.4 V vs. 48.4 V) make it a functional upgrade-provided the PCB layout is revised to accommodate the smaller, leadless footprint and thermal pad connection.
