Product details
Overview
5.0SMDJ100AH 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 features a 100 V working standoff voltage (VWM), 111–123 V breakdown voltage (VBR), 162 V maximum clamping voltage (VC) at 30.9 A peak pulse current, and 5000 W peak pulse power rating per 10/1000 µs waveform - deployed in automotive-grade AEC-Q101-qualified systems requiring robust ESD and lightning surge immunity.
For engineers reviewing the 5.0SMDJ100AH datasheet, 5.0SMDJ100AH pinout, 5.0SMDJ100AH application, or 5.0SMDJ100AH equivalent, key selection criteria include clamping performance under 30.9 A IPP, thermal derating above 25°C ambient, DO-214AB (SMC) package compatibility with automated SMT placement, and unidirectional polarity indicated by cathode band.
Technical Context
This TVS diode operates as a unidirectional clamping device, leveraging stacked-die construction to achieve high peak pulse power handling without sacrificing response time. Its junction-to-lead thermal resistance of 16 °C/W enables effective heat transfer to PCB copper pads during transient events.
The device complies with AEC-Q101 stress testing for automotive environments and exhibits <1.0 ps intrinsic response time, ensuring protection against fast-rising ESD and EFT transients. Its 175 °C maximum junction temperature and J-STD-020 Level 1 moisture sensitivity support reflow-compatible manufacturing.

Pinout & Package
5.0SMDJ100AH is housed in a DO-214AB (SMC) plastic package with two terminals: anode and cathode. Polarity is marked by a visible cathode band on the body. The device is unidirectional and must be oriented with cathode toward the protected line's positive rail.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | Lower peak power rating (600 W vs. 5000 W); same DO-214AA package but smaller thermal mass | Not suitable for load dump or high-energy industrial surges; limited to low-power I/O protection | Select only where surge energy is ≤600 W and board space constraints prohibit SMC footprint |
| SMCJ100A | Same DO-214AB (SMC) package and 5000 W rating, but VC = 165 V (vs. 162 V) and VBR min = 111 V (identical) | Functionally interchangeable in most 100 V rail designs; minor clamping voltage variance affects margin analysis | Valid alternative when sourcing flexibility is needed; verify layout clearance for identical SMC outline |
Compared with SMBJ100A and SMCJ100A, the 5.0SMDJ100AH delivers identical clamping performance to SMCJ100A but with tighter VC tolerance (162 V), while offering 8.3× higher surge capacity than SMBJ100A - making it the only choice for AEC-Q101-compliant, high-energy automotive and industrial deployments.

FAQ
What is the maximum clamping voltage of the 5.0SMDJ100AH under full-rated surge current?
The 5.0SMDJ100AH has a maximum clamping voltage (VC) of 162 V when subjected to its rated peak pulse current of 30.9 A, measured per the 10/1000 µs waveform. This value defines the upper voltage limit imposed on protected circuitry during worst-case transient events and is guaranteed across the full operating temperature range.
Is the 5.0SMDJ100AH suitable for bidirectional surge protection?
No, the 5.0SMDJ100AH is a unidirectional TVS diode, intended for use in DC circuits where polarity is fixed. It conducts only when the cathode is at a higher potential than the anode. For AC or reversible-polarity applications, a dedicated bidirectional part such as 5.0SMDJ100CA must be selected instead of the 5.0SMDJ100AH.
Does the 5.0SMDJ100AH require derating at elevated ambient temperatures?
Yes, the 5.0SMDJ100AH must be derated above 25°C ambient per its power derating curve. At 75°C lead temperature, its steady-state power dissipation drops to 6.25 W, and its peak pulse power capability decreases progressively with rising junction temperature - as shown in Figure 1 of the official datasheet.
What does the "AH" suffix indicate in the 5.0SMDJ100AH part number?
The "AH" suffix in 5.0SMDJ100AH denotes the unidirectional configuration and AEC-Q101 qualification grade. "A" specifies unidirectional polarity, and "H" indicates compliance with AEC-Q101 reliability stress testing for automotive applications - distinct from non-automotive variants like "A" or "CA" suffixes.
Can the 5.0SMDJ100AH be used in place of the SMCJ100A in existing designs?
Yes, the 5.0SMDJ100AH is physically and electrically compatible with SMCJ100A - both use DO-214AB (SMC) packaging, share identical VWM (100 V), VBR (111–123 V), and PPPPM (5000 W) ratings, and differ only in minor clamping voltage (162 V vs. 165 V). Layout reuse is fully supported without modification.
