Product details

Overview

JANTX1N6641US/TR from Microsemi is a hermetically sealed, metallurgically bonded, axial-lead switching diode in a D-5D glass package, rated for 75 V reverse working voltage (V_RWM), 5.0 ns reverse recovery time (t_rr), and 200 mA forward current (I_F), used in high-reliability military timing, pulse shaping, and clamping circuits.

For engineers reviewing the JANTX1N6641US/TR datasheet, JANTX1N6641US/TR pinout, JANTX1N6641US/TR application, or JANTX1N6641US/TR equivalent, key selection criteria include its 50 nA max reverse leakage at 10 µA test voltage, 3.0 pF junction capacitance at zero bias, -65°C to +175°C operating temperature range, and MIL-PRF-19500/609 qualification for space and defense systems.

Technical Context

The JANTX1N6641US/TR is a fast-switching, low-capacitance silicon diode optimized for high-speed digital and RF signal routing where minimal charge storage and rapid turn-off are critical. Its 5.0 ns reverse recovery time and 3.0 pF capacitance enable clean edge transitions in pulse generators and sample-and-hold circuits.

Designed per MIL-PRF-19500/609, it features a non-cavity glass case with tin/lead leads, 50 °C/W thermal resistance at L = 0, and polarity marked by cathode band. The device operates reliably across -65°C to +175°C without derating until +110°C.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar switching diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
JANTX1N6640US	Lower V_RWM (50 V), faster t_rr (4.0 ns), same package and temp range	Suitable for lower-voltage digital logic (<5 V rails) but not 75 V clamping	Select when circuit reverse voltage stays ≤50 V and sub-5 ns recovery is prioritized over voltage headroom.
JANTXV1N6641US	Same electrical specs, but qualified to higher JANTXV level with extended screening (e.g., 100% life test, enhanced radiation tolerance)	Required for mission-critical launch vehicle control systems where single-event latchup immunity is mandated	Choose when program requirements specify JANTXV-level reliability beyond standard JANTX.

Compared with JANTX1N6641US/TR, JANTX1N6640US trades voltage margin for marginally faster switching, while JANTXV1N6641US retains identical performance but adds verified radiation hardness-making the original optimal for cost-sensitive, high-temp, 75 V-rated military platforms where full JANTXV screening is unnecessary.
