Product details
Overview
5.0SMDJ64AHM6G from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, rated for 5000W peak pulse power at 10/1000μs, 64V working standoff voltage, and 103V maximum clamping voltage at 48.6A peak current. It is AEC-Q101 qualified and designed for automotive I/O interface and AC/DC power supply surge protection.
For engineers reviewing the 5.0SMDJ64AHM6G datasheet, 5.0SMDJ64AHM6G pinout, 5.0SMDJ64AHM6G application, or 5.0SMDJ64AHM6G equivalent, key selection criteria include clamping performance under 10/1000μs transients, junction temperature derating to 175°C, unidirectional polarity with cathode band marking, and compatibility with automated SMT placement on standard PCB land patterns.
Technical Context
This TVS diode uses a stacked-die construction to achieve high peak pulse power handling while maintaining low clamping ratio (VC/VBR ≈ 1.45) and fast response time (<1.0 ps). Its unidirectional configuration provides reverse-biased surge suppression with forward voltage of 5V at 100A, enabling integration into DC power rails where polarity is fixed.
Thermal design is supported by verified RθJL = 16°C/W and RθJA = 61°C/W on a 16mm × 16mm copper pad, allowing reliable operation up to TJ = 175°C. The device meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64A | Lower PPPM = 600W; same DO-214AA (SMB) package but smaller thermal mass | Not suitable for 5000W load dump events; limited to low-energy ESD and signal-line protection | Select only when peak surge energy is ≤600W and board space constraints favor SMB over SMC |
| 1.5KE68A | Through-hole TO-218 package; 1500W rating; higher VC/VBR ratio (≈1.59) | Requires manual insertion or wave soldering; incompatible with fully SMT production lines | Choose only for legacy through-hole designs where rework flexibility outweighs automation benefits |
Compared with SMBJ64A and 1.5KE68A, the 5.0SMDJ64AHM6G delivers 8.3× higher pulse power in an SMT-optimized package with tighter clamping ratio and automotive qualification-making it the sole option for AEC-compliant 64V rail protection in volume automotive electronics.

FAQ
What is the maximum clamping voltage of the 5.0SMDJ64AHM6G under a 10/1000μs surge?
The 5.0SMDJ64AHM6G has a maximum clamping voltage (VC) of 103 V when subjected to a 48.6 A peak pulse current with a 10/1000μs waveform. This value is measured per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during worst-case surge events. The 5.0SMDJ64AHM6G maintains this clamping performance across its specified operating temperature range and is validated in production test.
Is the 5.0SMDJ64AHM6G suitable for automotive applications?
Yes, the 5.0SMDJ64AHM6G is AEC-Q101 qualified and explicitly designed for automotive use cases including body control modules, infotainment power rails, and onboard charger auxiliary supplies. Its 175°C maximum junction temperature, JESD201 Class 2 whisker resistance, and moisture sensitivity level 1 rating meet stringent automotive manufacturing and field reliability requirements. The 5.0SMDJ64AHM6G data sheet confirms qualification test reports per AEC-Q101 Rev D.
What does the "M6G" suffix indicate in 5.0SMDJ64AHM6G?
The "M6G" suffix in 5.0SMDJ64AHM6G denotes Taiwan Semiconductor's internal packaging and environmental compliance coding: "M6" specifies tape-and-reel packaging with 3,000 units per reel, and "G" indicates green (halogen-free) molding compound compliant with IEC 61249-2-21. This matches the ordering information in the official 5.0SMDJ64AHM6G datasheet and is consistent across the 5.0SMDJxxAH family.
How does the 5.0SMDJ64AHM6G compare to bidirectional TVS diodes in the same voltage class?
The 5.0SMDJ64AHM6G is unidirectional and optimized for DC power rail protection where polarity is fixed, offering lower leakage (2 μA at VWM) and tighter clamping ratio than comparable bidirectional parts. Bidirectional variants like 5.0SMDJ64CA have symmetrical clamping but higher leakage and reduced power handling due to dual-junction structure. The 5.0SMDJ64AHM6G is not interchangeable with bidirectional types without circuit redesign.
What is the thermal resistance from junction to lead (RθJL) for the 5.0SMDJ64AHM6G?
The 5.0SMDJ64AHM6G has a typical junction-to-lead thermal resistance (RθJL) of 16°C/W when mounted on a 16 mm × 16 mm copper pad per JEDEC test conditions. This parameter is critical for calculating steady-state power dissipation limits and verifying safe operation under continuous leakage or repetitive surge conditions. The 5.0SMDJ64AHM6G datasheet confirms this value in its Thermal Performance table.
