Product details
Overview
T6N30CAHM3/H from Vishay General Semiconductor is a bidirectional 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, targeting automotive sensor line protection.
For engineers reviewing the T6N30CAHM3/H datasheet, T6N30CAHM3/H pinout, T6N30CAHM3/H application, or T6N30CAHM3/H equivalent, this device serves as a high-reliability, low-profile TVS for bidirectional transient suppression in space-constrained automotive electronics where MSL Level 1, side-wettable flanks, and 185 °C junction operation are required.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver stable bidirectional clamping under repetitive transients. Its DFN3820A package enables AOI-compatible automated placement and supports thermal management via low RθJM (6.5 °C/W max) and high TJ capability (185 °C).
The device operates across -65 °C to +185 °C junction temperature range and meets IEC 61000-4-2 ESD immunity up to ±30 kV (contact/air). Its 1.0 mA test current and ±5 % VBR tolerance (CA grade) ensure precise voltage thresholding in sensitive signal-line protection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar bidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30CA | DO-214AC package (SMA), higher RθJA (150 °C/W), 600 W rating, VC = 48.4 V @ 12.3 A | Larger footprint (4.5 × 2.7 mm), no side-wettable flanks, not AEC-Q101 qualified | Select when board space allows larger package and automotive qualification is not required |
| SMCJ33CA | DO-214AB package (SMC), 1500 W rating, VC = 53.3 V @ 28.2 A, same VBR range | 5.3 × 4.5 mm footprint, higher clamping voltage, suited for higher-energy transients | Select when surge energy exceeds 600 W and PCB layout accommodates larger case outline |

FAQ
What is the breakdown voltage tolerance for T6N30CAHM3/H?
The T6N30CAHM3/H has a ±5 % breakdown voltage tolerance, indicated by the "CA" suffix in its part number. Per the datasheet, its VBR is specified as 28.5 V (min), 30.0 V (nom), and 31.5 V (max) at 1.0 mA test current. This tight tolerance ensures consistent clamping behavior across production lots and supports precise circuit margining in automotive designs.
Is T6N30CAHM3/H compatible with lead-free reflow processes?
Yes, T6N30CAHM3/H is fully compatible with lead-free reflow processes. It meets JEDEC J-STD-020 MSL Level 1, allowing peak reflow temperatures up to 260 °C without preconditioning. Its matte tin-plated terminals comply with J-STD-002 and JESD 22-B102, and the HM3 suffix confirms compliance with JESD 201 Class 2 whisker testing-ensuring reliable solder joint formation in high-volume SMT lines.
Does T6N30CAHM3/H have polarity markings on the package?
No, T6N30CAHM3/H does not have polarity markings. As a bidirectional TVS, it features symmetric terminals with no cathode band-both terminals are functionally identical. The DFN3820A package uses non-polarized construction, enabling flexible PCB layout for AC-coupled or floating signal paths without orientation constraints during placement.
What is the maximum clamping voltage of T6N30CAHM3/H at its rated peak pulse current?
The maximum clamping voltage of T6N30CAHM3/H is 41.4 V at its rated peak pulse current of 14.5 A (10/1000 µs waveform). This value is measured per Figure 3 in the datasheet and represents the upper limit of voltage seen by downstream circuitry during worst-case surge events-critical for ensuring protected ICs remain within absolute maximum ratings.
How does the thermal performance of T6N30CAHM3/H compare to standard SMA packages?
T6N30CAHM3/H offers significantly better thermal performance than standard SMA packages: its RθJM is ≤6.5 °C/W versus ~15–20 °C/W for SMAJ-series devices. This lower junction-to-mount resistance enables more efficient heat transfer to the PCB copper, supporting sustained operation at TJ = 185 °C-whereas SMA devices typically max out at 150 °C-making T6N30CAHM3/H suitable for under-hood automotive locations.
