Another differentiator between the standard and Q-portfolio devices is the Product Change Notifications (PCN) period, which is extended from 90 days, according to JEDEC requirements, to 180 days. However, customer demands continue to evolve, and more non-automotive applications require additional quality-related services, such as PPAP (Production Part Approval Process) and extended longevity. The focus of these standards is to meet the Stress Test Qualification and quality management system requirements of automotive OEMs. The A-selection Zeners is also available as Q-portfolio devices, meeting the AEC-Q101 and ISO/TS16949 automotive quality standards. Once the Zener breaks through, the MOSFET switches on to stop the drain-source from going into an avalanche breakdown. Instead of protecting the MOSFET directly, a more cost-efficient alternative is to connect a Zener diode in parallel to the drain-gate path. The low tolerance provides a higher precision voltage, which is especially important for test & measurement applications and enables engineers to replace more costly voltages reference devices. The devices feature a non-repetitive peak reverse power dissipation of ≤40W, total power dissipation ≤250mW and low differential thermal resistance. The A-selection Zener diodes have a nominal working voltage range of 1.8 V to 75 V (E24 range). “By replacing B- or C-selection devices with pad compatible A-selection Zener devices, engineers can go to the limits of the MOSFET, if applied to limit voltage for the gate-source path or drain-gate path, or choose from a wider variety of suitable MOSFETs.†€œNexperia’s A-selection Zener diode range covers every application from 1.8 V to 75 V while providing a precise voltage reference with the lowest possible tolerance,†says Paula Stümer, product manager at Nexperia.
