The 1SZ53 is a Zener diode rated for 0.25 W continuous power dissipation. It is a general-purpose voltage-reference or clamping diode for low-current DC rails, protection circuits, and bias networks in consumer, industrial, and telecom boards.
The 1SZ53 is Active per the manufacturer lifecycle record. No end-of-life or last-time-buy notice is published for this part.
The 1SZ53 is rated for 0.25 W continuous power dissipation — suitable for low-current voltage reference or clamping applications.
No official cross-reference or second-source alternate is recorded for this order code. For a pin-compatible replacement, compare the 0.25 W Zener family from the same manufacturer or a standard Zener series (e.g., BZX84, 1N52xx) with matching voltage and power rating. Confirm the specific breakdown voltage from your application before substituting.
