Frequently Asked Questions
At what zener voltage does MMSZ5261B-V-GS08 clamp, and how accurate is this voltage under load?
The MMSZ5261B-V-GS08 clamps at a nominal 47V zener voltage with ±5% tolerance, meaning the actual clamp voltage ranges from 44.65V to 49.35V. Under load, the dynamic impedance of up to 105Ω can shift the voltage slightly with current, so for tight regulation designs, a lower-impedance reference diode may be preferred.
How much power can MMSZ5261B-V-GS08 dissipate continuously, and what limits its use in high-power circuits?
The MMSZ5261B-V-GS08 dissipates up to 500mW at 25°C ambient. In circuits where zener current exceeds approximately 10 mA at 47V, the power budget is consumed quickly, so adequate series resistance or active current limiting is required. For higher power applications exceeding 1W, larger DO-41 or SMB package zener diodes are recommended.
Which SMD footprint does MMSZ5261B-V-GS08 use, and is it compatible with standard pick-and-place assembly?
The MMSZ5261B-V-GS08 uses the SOD-323 (JESD-30 R-PDSO-G2) 2-pin SMD package with a rectangular plastic/epoxy body approximately 1.7 mm × 1.25 mm. This compact footprint is fully compatible with standard automated pick-and-place and reflow soldering assembly processes used in consumer electronics and telecommunications PCB manufacturing.
