Product details
Overview
5.0SMDJ24AHM6G from Taiwan Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power lines and I/O interfaces. It delivers 5000W peak pulse power at 10/1000μs, clamps transients to 38.9V at 129A, and features a 24V working standoff voltage with <2µA leakage. It is AEC-Q101 qualified and used in automotive power supply inputs.
For engineers reviewing the 5.0SMDJ24AHM6G datasheet, 5.0SMDJ24AHM6G pinout, 5.0SMDJ24AHM6G application, or 5.0SMDJ24AHM6G equivalent, key selection criteria include clamping voltage (VC = 38.9V), breakdown voltage range (26.7–29.5V), thermal resistance (RθJL = 16°C/W), unidirectional configuration, and DO-214AB (SMC) package compatibility with automated SMT assembly.
Technical Context
This TVS diode uses a stacked-die construction in a DO-214AB (SMC) package to achieve high peak pulse power handling while maintaining fast response (<1.0ps) and low clamping ratio. Its unidirectional polarity-indicated by a cathode band-enables integration into DC-biased circuits without reverse conduction during normal operation.
The device operates across –55°C to +175°C junction temperature, with thermal performance validated on a 16mm × 16mm copper pad PCB per JESD51-2. Its 0.096 mV/°C VBR temperature coefficient ensures stable breakdown behavior over temperature in automotive under-hood environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24A | Lower PPPM (600W), same DO-214AA (SMB) package, VBR 26.7–29.5V, VC = 38.9V | Not suitable for ISO 7637-2 load dump; limited to lower-energy surges | Select when cost-sensitive designs require basic I/O protection without automotive-level energy handling |
| 5.0SMDJ24A | Same electrical specs but non-AEC-Q101 rated; identical DO-214AB (SMC) package and marking code 5PEZ | Lacks automotive qualification; not approved for safety-critical vehicle subsystems | Use only in commercial/industrial applications where AEC-Q101 compliance is not mandated |
Compared with SMBJ24A and 5.0SMDJ24A, the 5.0SMDJ24AHM6G uniquely combines 5000W surge capability, AEC-Q101 qualification, and DO-214AB packaging-making it the only option among the three qualified for automotive load dump protection without derating or parallel devices.

FAQ
What is the clamping voltage of the 5.0SMDJ24AHM6G under maximum surge conditions?
The 5.0SMDJ24AHM6G has a maximum clamping voltage (VC) of 38.9 V when subjected to its peak impulse current (IPP) of 129 A under the 10/1000 µs waveform. This value is guaranteed per the manufacturer's electrical specifications table and reflects worst-case voltage seen by downstream circuitry during standardized surge events.
Is the 5.0SMDJ24AHM6G suitable for bidirectional surge protection?
No, the 5.0SMDJ24AHM6G is a unidirectional TVS diode, intended only for DC circuits with defined polarity. It does not provide symmetrical clamping for AC or reversible signals. For bidirectional protection, a dedicated bidirectional variant such as 5.0SMDJ24CAHM6G would be required.
What does the 'H' and 'M6G' suffix indicate in 5.0SMDJ24AHM6G?
The 'H' denotes the unidirectional configuration and AEC-Q101 qualification. 'M6G' specifies tape-and-reel packaging (3,000 units per reel), green molding compound (halogen-free), and standard JEDEC-compliant DO-214AB (SMC) outline-consistent with Taiwan Semiconductor's ordering nomenclature in the datasheet.
How does the thermal performance of 5.0SMDJ24AHM6G affect PCB layout?
The 5.0SMDJ24AHM6G has RθJL = 16°C/W and RθJA = 61°C/W when mounted on a 16 mm × 16 mm copper pad. To maintain TJ ≤ 175°C under repeated surges, designers must allocate ≥200 mm² of 2-oz copper connected directly to both terminals, avoiding narrow traces that increase thermal resistance.
Can the 5.0SMDJ24AHM6G replace older 5.0SMDJ24A parts in existing designs?
Yes, the 5.0SMDJ24AHM6G is a direct form-fit-function replacement for 5.0SMDJ24A in the same DO-214AB (SMC) package, with identical electrical parameters and marking code (5PEZ). The 'H' version adds AEC-Q101 qualification and enhanced process controls-but requires no PCB or schematic changes.
