Product details
Overview
5.0SMDJ90A 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 146V at 34.3A, and features a 90V working standoff voltage with <1.0ps response time. It is used in AC/DC power supplies to protect downstream regulators and controllers from lightning-induced surges.
For engineers reviewing the 5.0SMDJ90A datasheet, 5.0SMDJ90A pinout, 5.0SMDJ90A application, or 5.0SMDJ90A equivalent, key selection criteria include its DO-214AB (SMC) package compatibility, unidirectional polarity marking, 175°C max junction temperature, and verified clamping performance under IEC 61000-4-5 surge conditions.
Technical Context
The 5.0SMDJ90A employs a stacked-die construction to achieve high peak pulse power handling while maintaining low clamping voltage. Its photo-glass passivated junction ensures stable breakdown behavior and long-term reliability under repetitive surge stress.
Designed for automated SMT placement, it meets J-STD-020 moisture sensitivity level 1 and JESD 201 class 2 whisker resistance. The device operates across –55°C to +175°C and exhibits a VBR temperature coefficient of 0.110 mV/°C, enabling predictable voltage drift in thermal-cycling environments.

Applications
| AC/DC Power Supply Input Protection | I/O Interface Surge Suppression |
|---|---|
Use Scenario: Protecting primary-side rectifier outputs and secondary-side DC bus lines in offline switch-mode power supplies against lightning-induced surges. IC Role / Device Role / Timing Role: Unidirectional TVS diode placed across input capacitor or post-rectifier node to clamp differential-mode transients. Use Value: Limits peak voltage to 146V during 5000W surges, preventing damage to bridge rectifiers, bulk capacitors, and controller ICs rated ≤150V. | Use Scenario: Shielding RS-485, CAN, or Ethernet PHY interface lines from ESD and fast-rising EFT bursts. IC Role / Device Role / Timing Role: Standoff-clamp TVS connected between signal line and ground, leveraging sub-nanosecond response to intercept transients before receiver input stages. Use Value: Maintains signal integrity by clamping transients below 146V while adding <0.5pF junction capacitance-negligible impact on 10 Mbps+ data rates. |
| Industrial Motor Drive DC Bus | Telecom Rectifier Module Output |
Use Scenario: Safeguarding 90V-rated gate drivers and current-sense amplifiers on motor drive DC link buses exposed to inductive switching spikes. IC Role / Device Role / Timing Role: Unidirectional TVS mounted directly at bus capacitor terminals to absorb repetitive 5000W commutation energy. Use Value: Withstands 175°C junction temperature and 0.110 mV/°C VBR drift, ensuring stable clamping across wide ambient ranges in enclosed enclosures. | Use Scenario: Protecting -48V telecom rectifier outputs from load-dump transients and hot-swap events in central office power systems. IC Role / Device Role / Timing Role: High-power TVS placed at rectifier output filter stage to limit voltage excursions during sudden load disconnection. Use Value: Delivers 5000W pulse rating with 6.25W steady-state dissipation on standard PCB layout-no external heatsink required for intermittent surge duty. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ90A | Lower PPPM (600W), same DO-214AA package, 146V VC but only 34.3A IPP | Not suitable for IEC 61000-4-5 Level 4; limited to lower-energy ESD/EFT scenarios | Select 5.0SMDJ90A when 5000W surge immunity is required; SMBJ90A may be used where space constraints favor smaller footprint. |
| SMCJ90A | Same 5000W rating and DO-214AB package, but higher VF (5.0V) and identical VC (146V) | Functionally interchangeable in most 90V rail protection roles; minor thermal resistance variation (RθJA = 55°C/W vs. 61°C/W) | SMCJ90A offers marginally better thermal performance; 5.0SMDJ90A provides tighter VBR tolerance (100–111V vs. 100–112V) and lower leakage at VWM. |
Compared with SMBJ90A and SMCJ90A, the 5.0SMDJ90A delivers identical clamping voltage and superior VBR consistency while maintaining full 5000W surge capability in the DO-214AB package-making it optimal for high-reliability industrial power and telecom infrastructure where precise voltage control and robust surge margin are critical.

FAQ
What is the maximum clamping voltage of the 5.0SMDJ90A under specified test conditions?
The 5.0SMDJ90A has a maximum clamping voltage (VC) of 146 V when subjected to a peak pulse current (IPP) of 34.3 A using the 10/1000 µs waveform. This value is guaranteed per the manufacturer's electrical specifications table and defines the upper voltage limit imposed on protected circuits during surge events.
Does the 5.0SMDJ90A support bidirectional transient suppression?
No, the 5.0SMDJ90A is a unidirectional TVS diode, indicated by its "A" suffix and cathode band marking. It conducts only during reverse-bias overvoltage events and must be oriented with cathode toward the protected line. For bidirectional protection, a separate part such as 5.0SMDJ90CA would be required.
What is the thermal resistance from junction to ambient for the 5.0SMDJ90A?
The junction-to-ambient thermal resistance (RθJA) of the 5.0SMDJ90A is 61 °C/W, measured on a standard 16 mm × 16 mm copper pad test board. This value guides thermal design for sustained power dissipation and must be adjusted for actual PCB layout and copper area.
How does the 5.0SMDJ90A differ from the 5.0SMDJ100A in terms of voltage ratings?
The 5.0SMDJ90A has a working standoff voltage (VWM) of 90 V and breakdown voltage range of 100–111 V, whereas the 5.0SMDJ100A specifies VWM = 100 V and VBR = 111–123 V. Both share identical 5000W PPPM and 146V/162V clamping voltages respectively, making them non-interchangeable without verifying system voltage margins.
Is the 5.0SMDJ90A compliant with RoHS and halogen-free standards?
Yes, the 5.0SMDJ90A is RoHS compliant and halogen-free per IEC 61249-2-21. Its molding compound meets UL 94V-0 flammability rating, and its matte tin-plated leads satisfy J-STD-002 solderability requirements-ensuring suitability for environmentally regulated industrial and telecom end equipment.
