Re: Q: Replacement for BS170?


 

Tony S., AC9QY,? first identified TN0110 and TN0106 as potential replacements for BS170.

This is what he found attractive:

- lower threshold voltage
- higher avalanche voltage (TN0110 = 100V)
- better case thermal resistance

The pinout reversal was annoying but folks have found ways to cope with that.

Would someone kindly remind me why the substitutes for the BS170?
Are the originals hard to find? Are alternatives considered to be an improved choice?
I currently perceive the BS170 as being fairly common and cheap.
