Product details

Overview

JANTXV1N6642U from Microsemi is a hermetically sealed, metallurgically bonded, axial-lead switching diode in a non-cavity glass D-5D package, rated for 75 V reverse working voltage (V_RWM), 100 V peak reverse voltage (V_BR), and 100 mA pulsed forward current (I_F), used in high-reliability timing, clamping, and pulse shaping circuits in aerospace power conditioning systems.

For engineers reviewing the JANTXV1N6642U datasheet, JANTXV1N6642U pinout, JANTXV1N6642U application, or JANTXV1N6642U equivalent, key selection criteria include its 5.0 ns reverse recovery time (t_rr), 20 ns forward recovery time (t_fr), 1.2 V forward voltage at 10 mA (V_F2), -65°C to +175°C operating temperature range, and MIL-PRF-19500/578 qualification for space-grade transient suppression.

Technical Context

The JANTXV1N6642U 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 pF capacitance at 20 V and 2.8 pF at V_RWM support stable impedance matching in pulse generator front-ends.

It operates with 25 nA reverse leakage at 75 V (I_R1) and maintains 50 µA leakage at 150°C (I_R3), enabling reliable performance in thermally stressed avionics environments without thermal runaway. The device's metallurgical bond and hermetic D-5D package ensure long-term stability under thermal cycling and radiation exposure.

Key Specifications

V_RWM	75 V dc - Maximum continuous reverse voltage before significant leakage; defines safe operating window in clamp circuits.
V_BR	100 V pk - Breakdown voltage at I_R = 100 µA; sets overvoltage protection threshold in transient suppressors.
t_rr	5.0 ns - Reverse recovery time at I_F = 100 mA, I_R = 1 mA; enables >100 MHz switching in pulse shapers.
V_F2	1.2 V @ 10 mA - Forward voltage drop defining conduction loss and self-heating in low-duty-cycle drivers.
C_T @ 20 V	5.0 pF - Junction capacitance limiting bandwidth degradation in RF detector inputs and sampling gates.
Operating Temp	-65°C to +175°C - Full military temperature range supported by hermetic glass package and metallurgical bond.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
JANTXV1N6643U	Lower V_RWM (50 V), higher t_rr (6.0 ns), higher leakage at 150°C (75 µA)	Better suited for lower-voltage, higher-temperature bias networks where speed is secondary to leakage control	Select when V_RWM margin <25 V and thermal derating dominates recovery speed requirements
JANTXV1N6638U	Higher V_RWM (125 V), lower t_rr (4.5 ns), lower C_T (2.5 pF @ 20 V)	Preferred for >100 V transient suppression and ultra-high-frequency sampling where capacitance must be minimized	Select when system V_R exceeds 90 V or bandwidth >500 MHz is required

Compared with JANTXV1N6643U and JANTXV1N6638U, the JANTXV1N6642U offers optimal balance of 75 V standoff, 5.0 ns recovery, and 2.8 pF capacitance-making it the default choice for 28–70 V aerospace bus interfaces requiring MIL-qualified speed and reliability without over-specifying voltage rating.

FAQ

What is the maximum junction temperature rating for JANTXV1N6642U?

The JANTXV1N6642U has a maximum junction temperature of +175°C and a minimum of -65°C, fully compliant with MIL-PRF-19500/578. This rating is enabled by its hermetic D-5D glass package and metallurgical bond construction, allowing uninterrupted operation in engine bay or payload bay thermal environments where ambient temperatures exceed 125°C. Derating begins above +110°C at 4.6 mA/°C.

Is JANTXV1N6642U suitable for use in radiation-exposed environments?

Yes, JANTXV1N6642U is qualified to MIL-PRF-19500/578 and features a hermetically sealed D-5D glass package with metallurgical bonding-both proven to withstand total ionizing dose (TID) levels exceeding 100 krad(Si) and single-event effects (SEE) immunity appropriate for low-earth orbit missions. Radiation test reports are available under NDA from Microchip.

Does JANTXV1N6642U have a specified surge current rating?

Yes, JANTXV1N6642U is rated for 2.5 A surge current (I_FSM) using a half-sine wave with 8.3 ms pulse width, per MIL-PRF-19500/578. This rating validates its use in power-line transient suppression and motor-commutation snubbers where short-duration overcurrent events occur. The metallurgical bond prevents interfacial delamination under repeated surge stress.

What is the cathode identification method on JANTXV1N6642U?

The cathode of JANTXV1N6642U is identified by a visible band on the glass body near one axial lead, consistent with MIL-PRF-19500/578 mechanical drawings. This band must align with the ground or lower-potential node in clamping configurations. Polarity verification is confirmed via diode test mode on calibrated bench equipment before board assembly.

How does the thermal impedance of JANTXV1N6642U affect PCB layout?

JANTXV1N6642U has a maximum thermal impedance Z_θJX of 25°C/W, measured from junction to external mounting surface. To maintain T_J ≤ 175°C at 100 mA pulsed current, PCB land patterns must provide ≥10 mm² copper area per lead with ≥2 internal thermal vias per pad. Mounting surface coefficient of expansion (COE ≈ +4 ppm/°C) must match substrate material to prevent solder joint fatigue.
