Engineering Selection Recommendations

ZXTP5401ZTA (Diodes Incorporated): This part is a direct functional equivalent manufactured by the same supplier as the DXT5401-13. It maintains identical electrical specifications for collector current, breakdown voltage, saturation voltage, and DC current gain. The ZXTP5401ZTA provides enhanced power dissipation capability at 1.2 W compared to the 1 W rating of the DXT5401-13, offering additional design margin. Both parts are RoHS3 compliant with identical moisture sensitivity classification and operating temperature range. Package compatibility is confirmed with SOT-89-3 footprint. This substitution is suitable for direct replacement in existing designs.

CXT5401 TR PBFREE (Central Semiconductor Corp): This part meets all primary electrical substitution criteria with matching collector current and breakdown voltage specifications. The CXT5401 TR PBFREE provides enhanced transition frequency at 300 MHz compared to the 100 MHz of the DXT5401-13, supporting higher-speed switching applications. Power dissipation is rated at 1.2 W. Operating temperature range extends to -65°C, providing wider low-temperature capability. RoHS3 compliance is confirmed. Package footprint is TO-243AA with SOT-89 configuration. This substitution is suitable for applications requiring higher frequency response.

2SA1418S-TD-E (Sanyo): This part exceeds the DXT5401-13 specifications in collector current (700 mA versus 600 mA) and breakdown voltage (160 V versus 150 V). DC current gain is enhanced at 100 minimum. However, maximum power dissipation is rated at 500 mW, which is below the 1 W rating of the DXT5401-13. This part is classified as a manufacturer-recommended alternative suitable for applications where enhanced current and voltage ratings are beneficial and power dissipation requirements do not exceed 500 mW. RoHS compliance status is not specified in the provided data. Package compatibility is confirmed as TO-243AA.

Frequently Asked Questions (FAQ)

Q: Can ZXTP5401ZTA be used as a direct replacement for DXT5401-13?

A: Yes. The ZXTP5401ZTA is manufactured by Diodes Incorporated and maintains identical electrical specifications for all critical parameters including collector current (600 mA), breakdown voltage (150 V), saturation voltage, and DC current gain. Both parts use the SOT-89-3 package with TO-243AA case. The ZXTP5401ZTA provides additional power dissipation margin at 1.2 W. Direct substitution is supported.

Q: What is the primary difference between CXT5401 TR PBFREE and DXT5401-13?
