130 V zener with military temperature range
The 1N6027B is a 130 V zener diode rated for 500 mW continuous power dissipation in a DO-35 axial package. The ±5% tolerance is the standard precision grade for general-purpose voltage regulation and clamping in this voltage class. The 950 Ohm maximum dynamic impedance (Zzt) at the zener test current means the regulation slope is relatively soft — expect a few volts of shift between the knee current and full rated current.
The DO-35 glass package is a standard through-hole footprint — no board-spin required for a drop-in replacement of an existing 130 V zener in the same package. The base product number 1N6027 covers the full family; the B suffix denotes the ±5% tolerance bin.
