Overview
The CMKZ5245B TR is a surface mount triple isolated silicon Zener diode from the Central Semiconductor CMKZ5221B series, packaged in an ULTRAmini SOT-363 case. It contains three independent Zener diodes with a nominal voltage of 15 V (min 14.25 V, max 15.75 V) at a test current of 8.5 mA. Each diode has a maximum power dissipation of 200 mW and operates within a junction temperature range of -65 to +150 °C. The device features a maximum Zener impedance of 16 Ω at IZT and 600 Ω at IZK, with a reverse current of 0.1 μA at 11 V. The thermal resistance is 625 °C/W, and it carries a temperature coefficient of +0.082 %/°C.

Procurement Notes
This component is classified as End of Life (EOL). No new production is available; only existing stock may be sourced. Last purchase orders were accepted six months after the discontinuation notice, with final shipments occurring twelve months post-notice. Verify stock availability directly with suppliers or distributors, as standard ordering channels no longer support active procurement.
Selection Notes
Select this part only if legacy compatibility is required, as it is discontinued. Ensure the design accommodates the specific 15 V nominal voltage and 200 mW per-diode power rating. Consider alternative modern triple-Zener packages if long-term supply assurance is critical, given the EOL status and lack of official replacements.
Part Context
The CMKZ5245B TR belongs to the CMKZ5221B through CMKZ5261B series of triple isolated silicon Zener diodes. This series offers various voltage options within the same SOT-363 footprint, allowing designers to choose specific breakdown voltages while maintaining consistent mechanical and thermal characteristics across the family.
Replacement Considerations
No official replacement part numbers are listed by Central Semiconductor for the CMKZ5245B TR. The manufacturer indicates that no direct substitutes are available and suggests contacting engineering for alternate source assistance.
