Overview
The STZ6.8TFHT146 is a Zener diode manufactured by Rohm Semiconductor, designed for surface-mount applications in the SOD-323FL package. It features a nominal Zener voltage of 6.8 V with a tolerance range typically spanning from 6.53 V to 7.07 V at a test current of 5 mA. The device supports a maximum power dissipation of 500 mW and operates within a junction temperature range up to 150 °C. Storage temperatures extend from -55 °C to 150 °C. This component is suitable for voltage regulation and protection circuits requiring compact form factors.
Feature Summary
- Compact SOD-323FL surface-mount package design
- Stable Zener voltage regulation at 6.8 V nominal
- High thermal stability with 150 °C junction limit
Applications
- Voltage reference circuits
- Over-voltage protection
- Clamping applications
Procurement Notes
Verify the specific ordering code suffix against the manufacturer's latest datasheet to ensure correct packaging and tape specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer before placing orders, as supply chain conditions may vary.
Selection Notes
Select this component when a low-profile SOD-323FL footprint is required for 6.8 V Zener regulation. Ensure the circuit design accommodates the 500 mW power dissipation limit and verify that the 5 mA test current aligns with the target application's operating conditions for accurate voltage referencing.
Part Context
This part belongs to Rohm's standard Zener diode portfolio, offering reliable voltage regulation in small packages. It serves as a fundamental passive component for stabilizing voltages in consumer electronics and industrial control systems where space constraints necessitate compact surface-mount solutions.
Replacement Considerations
Check for direct cross-references from other manufacturers offering identical 6.8 V Zener diodes in SOD-323FL packages. Verify pinout compatibility and electrical parameter equivalence, particularly regarding Zener impedance and power ratings, before substituting.
