1N5738D [Microchip]

These are 0.5 watt axial-leaded Zener voltage regulators in DO-35 (DO-204AH) glass package. The series offers voltage regulation from 4.7V to 75V with standard ±5% tolerance (B suffix), and tighter ±2% (C suffix) or ±1% (D suffix) options. Key features include JEDEC registration, internal metallurgical bond option (-1 suffix), MIL-PRF-19500 screening availability (JAN/JANTX/JANTXV/JANS with MQ/MX/MV/MSP prefixes), surface-mount equivalents (DO-213AA with UR/UR-1 suffix), and DO-7 glass body equivalents. The devices provide flexible axial-lead mounting, are non-sensitive to ESD per MIL-STD-750 Method 1020, have minimal capacitance, and are inherently radiation-hardened.
