Products Detail

These glass axial-leaded DO-35 Zeners are also available in various military screening levels by adding a prefix identifier as described in the Features section. Microsemi also offers numerous other Zener products to meet higher and lower power applications. The series is JEDEC registered and offers internal bonds optionally available with '-1' suffix. Options for screening in accordance with MIL-PRF-19500 for JAN, JANTX, JANTXV, and JANS are available by adding MQ, MX, MV, or MSP prefixes respectively to part numbers with '-1' suffix. Surface mount equivalents available as MLL5221 to MLL5281B in the DO-213AA MELF style package including '-1' suffix options. RoHS Compliant devices available by adding 'e3' suffix. DO-7 glass body axial-leaded Zener equivalents are also available.
