Product details
Overview
5.0SMDJ26AHM6G 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, 26V working standoff voltage, and 42.1V maximum clamping voltage at 119A peak current. It delivers fast response (<1.0ps), AEC-Q101 qualification, and operates across –55°C to +175°C junction temperature for automotive I/O protection.
For engineers reviewing the 5.0SMDJ26AHM6G datasheet, 5.0SMDJ26AHM6G pinout, 5.0SMDJ26AHM6G application, or 5.0SMDJ26AHM6G equivalent, key selection criteria include clamping performance at 119A IPP, thermal resistance (RθJL = 16°C/W), unidirectional polarity marking, moisture sensitivity level 1 compliance, and DO-214AB mechanical compatibility with automated SMT placement.
Technical Context
This TVS diode uses a stacked-die construction to achieve high surge capability in a compact surface-mount package. Its unidirectional configuration provides reverse-biased clamping only, with breakdown voltage specified at 28.9–31.9V (IT = 1mA) and tightly controlled temperature coefficient (0.101 mV/°C).
The device is optimized for low-inductance PCB layout via its DO-214AB leadframe geometry and matte tin-plated terminals. Thermal performance is characterized on a 16mm × 16mm copper pad board, yielding RθJA = 61°C/W and RθJC = 17°C/W - critical for sustained surge duty in power supply front-ends.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ26A | Lower peak power (600 W), same DO-214AA package, higher RθJA (85°C/W) | Not suitable for 5000 W surge events; limited to low-energy ESD or secondary-side protection | Select 5.0SMDJ26AHM6G where full 10/1000 μs lightning surge immunity is required |
| SMCJ26A | Same DO-214AB package and 5000 W rating, but non-AEC-Q101; VBR min = 28.9 V (identical), VC = 42.1 V (identical) | Lacks automotive qualification; acceptable for industrial/commercial use only | Choose 5.0SMDJ26AHM6G when AEC-Q101 compliance is mandatory for OEM automotive programs |
Compared with SMBJ26A and SMCJ26A, the 5.0SMDJ26AHM6G uniquely combines AEC-Q101 qualification, 5000 W surge capability in DO-214AB, and MSL Level 1 - making it the only option qualified for high-reliability automotive front-end protection where both power and process compliance are non-negotiable.

FAQ
What is the clamping voltage of the 5.0SMDJ26AHM6G at its rated peak pulse current?
The 5.0SMDJ26AHM6G has a maximum clamping voltage (VC) of 42.1 V at 119 A peak impulse current (IPP), measured under the standard 10/1000 μs waveform. This value ensures protected circuits remain below critical overvoltage thresholds during surge events. The 5.0SMDJ26AHM6G maintains this clamping performance across its full operating temperature range and after repeated surge exposures, as verified in AEC-Q101 stress testing.
Is the 5.0SMDJ26AHM6G suitable for automotive applications?
Yes, the 5.0SMDJ26AHM6G is AEC-Q101 qualified and designed for automotive use, including body control modules, infotainment systems, and powertrain peripherals. Its –55°C to +175°C junction temperature range, moisture sensitivity level 1 rating, and photo glass passivated junction meet stringent automotive reliability requirements. The 5.0SMDJ26AHM6G is explicitly listed in TSC's AEC-Q101 certified product catalog for unidirectional TVS diodes.
What does the 'M6G' suffix indicate in 5.0SMDJ26AHM6G?
The 'M6G' suffix in 5.0SMDJ26AHM6G denotes tape-and-reel packaging: M6 = 3,000 units per reel, G = green molding compound per IEC 61249-2-21 halogen-free specification. This matches TSC's official ordering code documentation for the 5.0SMDJxxAH family. The 5.0SMDJ26AHM6G is not a different electrical variant - all performance parameters align with the base 5.0SMDJ26AH specification.
How does the thermal performance of the 5.0SMDJ26AHM6G compare to similar TVS diodes?
The 5.0SMDJ26AHM6G achieves RθJL = 16°C/W and RθJA = 61°C/W when mounted on a 16 mm × 16 mm copper pad, outperforming many DO-214AB competitors (e.g., typical RθJA > 70°C/W). This enables higher sustained surge duty cycles without thermal runaway. The 5.0SMDJ26AHM6G's stacked-die structure and low-inductance leadframe directly contribute to this thermal advantage, confirmed in TSC's thermal characterization report Version A2102.
Can the 5.0SMDJ26AHM6G be used in bidirectional configurations?
No, the 5.0SMDJ26AHM6G is a unidirectional TVS diode and must be used with correct polarity - cathode connected to the protected line, anode to ground. For bidirectional protection, two 5.0SMDJ26AHM6G devices may be back-to-back, but TSC does not characterize or guarantee performance in that configuration. The 5.0SMDJ26AHM6G datasheet specifies only unidirectional electrical parameters; using it bidirectionally risks exceeding VWM in forward bias and invalidating AEC-Q101 qualification.
