דיודות

[frogi123]

האם יש הבדל כזה גדול בין דיודה 1N4148 לבין 1N4146
אני יודע שיש הבדל,אבל במעגל שיש לי משורטט שני דיודות 1N4148 ,המעגל הזה הוא לבניית פרוגמר לPIC16F84,האם אני יכול לשים דיודה אחת 1N4148 והשנייה 1N4148
ראו קישור מצורף-בו מופיע השרטוט.




תודה

אז אם אתם רואים יש שם 2 טרנזיסטורים שלא מסומן הערך שלהם.
אמרו לי בחנות אלק' שהם משמשים למפסקים וכדאי לשים שם 0.7 בערך.
עזרו לי,ואמרו לי מה הכוונה במפסקים? ואיך ערך הכי מתאים שם.

תודה

שלום איציק,

ראשית, לדעתי אין כל מניעה להשתמש ב-1N4146 במקום ב-1N4148. הן דיודות מאוד דומות, אך 1N4148 יותר נפוצה. האם בחנות יש רק 1N4146 ?

לגבי הטרנזיסטורים, אתה יכול להשתמש ב-2N3906. הוא נפוץ יחסית וככל הנראה יתאים לצרכיך.

בברכה,

בחנות יש את שתי הסוגים,פשוט יכול להיות שהיא לא ראתה טוב ונתנה אחד כזה ואחד כזה.
לגבי הטרנזיסטורים-תודה.
