Good value
Works as expected. The only reason for 4 stars is that the delivery took a day longer than estimated, but the product itself is flawless.

Saved my vintage amp
Needed a specific 51V zener for an old amplifier restoration. This SMA package fit perfectly and works great.

Perfect replacement part
Exactly what I needed for my power supply repair. The voltage regulation is spot on at 51V. Fast shipping and well packaged.
Q: Is this diode suitable for high temperature environments?
A: Yes, the 3SMAJ5942B-TP has an operating temperature range of -55°C to +150°C, making it suitable for demanding environments.
Q: Can I use this as a direct replacement for a 1N5372B?
A: While both are 51V Zener diodes, the 1N5372B is typically in a DO-15 package. Ensure your board layout supports the smaller SMA (DO-214AC) footprint before substituting.
Q: Does this part come with a certificate of conformity?
A: Yes, all our semiconductor products ship with a standard certificate of conformity confirming RoHS compliance and authenticity.
Q: Are these components sold individually or in reels?
A: This listing is for individual units cut from the reel. If you require full reel quantities, please contact our sales team directly.
Q: What is the exact footprint for PCB design?
A: The component uses the standard DO-214AC (SMA) footprint. Please refer to the manufacturer's datasheet for detailed land pattern recommendations.
