Product details
Overview
5.0SMDJ36AH 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 at 58.1V under 86.1A surge current, and features a 40.0–44.2V breakdown voltage range with <1.0ps response time. It is AEC-Q101 qualified and used in automotive power supply inputs.
For engineers reviewing the 5.0SMDJ36AH datasheet, 5.0SMDJ36AH pinout, 5.0SMDJ36AH application, or 5.0SMDJ36AH equivalent, key selection criteria include its DO-214AB (SMC) package, unidirectional polarity, 36V working standoff voltage, 58.1V clamping performance, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This TVS diode uses a stacked-die construction to achieve high peak pulse power handling in a compact SMC package. Its unidirectional configuration provides low forward voltage (5V @ 100A) and precise reverse standoff behavior, enabling robust protection of downstream ICs without interfering with normal signal or power operation.
The device operates across –55°C to +175°C junction temperature, supported by a 16°C/W junction-to-lead thermal resistance. Its 0.096 mV/°C VBR temperature coefficient ensures stable breakdown voltage over temperature, critical for automotive environments where thermal drift must be minimized.

|---|---|---|---|
| SMBJ36A | Lower peak power (600W), same DO-214AA package, 36V VWM, 58.1V VC | Not AEC-Q101 qualified; suitable for commercial-grade power supplies but not automotive | Select SMBJ36A only if 5000W surge capacity is unnecessary and cost or board space is constrained |
| SMCJ36A | Same DO-214AB package and 5000W rating, but VBR min = 40.0V (identical), VC = 58.1V (identical), no AEC-Q101 documentation confirmed | Lacks published AEC-Q101 qualification evidence; may require additional validation for automotive use | Choose SMCJ36A when AEC-Q101 is not mandated and sourcing flexibility is prioritized |

FAQ
What is the clamping voltage of the 5.0SMDJ36AH under maximum rated surge current?
The 5.0SMDJ36AH has a maximum clamping voltage (VC) of 58.1 V when subjected to its peak pulse current (IPP) of 86.1 A under the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuits during worst-case surge events. The 5.0SMDJ36AH maintains this clamping performance across its full operating temperature range.
Is the 5.0SMDJ36AH suitable for automotive applications?
Yes, the 5.0SMDJ36AH is AEC-Q101 qualified, making it suitable for automotive applications including engine control units, body control modules, and infotainment power supplies. Its –55°C to +175°C junction temperature range, low VBR temperature coefficient (0.096 mV/°C), and DO-214AB package with matte tin leads meet automotive reliability and solderability requirements. The 5.0SMDJ36AH is explicitly designed for this environment.
What does the "AH" suffix indicate in 5.0SMDJ36AH?
The "AH" suffix in 5.0SMDJ36AH denotes a unidirectional TVS diode in the DO-214AB (SMC) package with AEC-Q101 qualification and halogen-free construction. It distinguishes this variant from bidirectional versions (e.g., "CAH") and confirms compliance with IEC 61249-2-21. The 5.0SMDJ36AH marking code "5PFP" further identifies it within Taiwan Semiconductor's standardized SMDJ family.
How does the 5.0SMDJ36AH compare to standard SMBJ-series TVS diodes?
The 5.0SMDJ36AH delivers 5000W peak pulse power-over eight times higher than the 600W rating of SMBJ36A-while sharing the same 36V working voltage and ~58V clamping level. It also adds AEC-Q101 qualification, tighter VBR tolerance (40.0–44.2V vs. typical 40.0–46.0V), and lower temperature coefficient. The 5.0SMDJ36AH is physically larger (DO-214AB vs. DO-214AA) to accommodate its higher energy rating.
What is the maximum leakage current of the 5.0SMDJ36AH at its working voltage?
The maximum blocking leakage current (IIB) of the 5.0SMDJ36AH is 2 µA at its rated working standoff voltage (VWM) of 36 V and ambient temperature of 25°C. This low leakage ensures minimal power loss and no interference with upstream voltage regulation or monitoring circuits. The 5.0SMDJ36AH maintains this specification across its full storage temperature range (–55°C to +175°C).
