Product details
Overview
JANTXV1N6642 from Microsemi is a military-qualified ultra-fast switching diode in hermetically sealed "D" package, featuring 75 V working peak reverse voltage (VRWM), 5.0 ns reverse recovery time (trr), and 0.8 V forward voltage at 10 mA. It serves as a high-reliability replacement for 1N4148/1N4150 in fast data-line and interface applications requiring stable performance across –65 °C to +175 °C.
For engineers reviewing the JANTXV1N6642 datasheet, JANTXV1N6642 pinout, JANTXV1N6642 application, or JANTXV1N6642 equivalent, this page delivers verified electrical specs, thermal limits, polarity marking, and direct alternatives for MIL-PRF-19500/578-compliant designs in aerospace, defense computing, and ruggedized communications hardware.
Technical Context
The JANTXV1N6642 employs metallurgically bonded construction inside a voidless hard-glass non-cavity package, enabling reliable operation under extreme thermal cycling and radiation environments. Its 5.0 ns trr and 2.8 pF junction capacitance at 1.5 V support signal integrity in >10 MHz digital switching paths.
Rated for 300 mA average rectified current at +75 °C with 150 °C/W junction-to-lead thermal resistance, it sustains pulsed surge currents up to 2.5 A (8.3 ms half-sine) while maintaining ≤100 nA reverse leakage at VRWM and +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 75 V - Maximum continuous reverse voltage before breakdown in normal operation. |
| trr | 5.0 ns - Time required to transition from forward conduction to reverse blocking at IF = IR = 10 mA. |
| VF @ 10 mA | 0.8 V - Forward voltage drop ensuring low power loss in logic-level clamping and steering circuits. |
| CJ @ 1.5 V | 2.8 pF - Low junction capacitance preserving signal edge fidelity on high-speed data lines. |
| IO @ +75 °C | 300 mA - Continuous forward current rating with linear derating above +75 °C. |
| TJ / TSTG | –65 °C to +175 °C - Full military temperature range for operation and storage without parameter drift. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-fast switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4148W-TP (Micro Commercial) | Commercial grade only; 4.0 ns trr, 100 V VRWM, SOD-123 surface-mount package. | Lacks MIL-PRF-19500 qualification; unsuitable for flight-critical or extended-temperature deployments. | Select when cost-sensitive commercial designs require faster trr but do not mandate hermetic sealing or military screening. |
| JANTXV1N6638 (Microsemi) | Higher VRWM (125 V), same trr (4.5 ns), identical "D" package and qualification level. | Better suited for 100–120 V rail protection; otherwise functionally interchangeable in 75 V systems with margin. | Choose for designs needing higher reverse standoff without changing layout or thermal design. |
Compared with JANTXV1N6642, the 1N4148W-TP offers faster switching in a compact SMT form but lacks hermeticity and military screening, while JANTXV1N6638 provides higher reverse voltage headroom with identical thermal and mechanical behavior in the same "D" package.

FAQ
What is the maximum reverse voltage rating for JANTXV1N6642?
The JANTXV1N6642 has a working peak reverse voltage (VRWM) of 75 V and a minimum breakdown voltage (VBR) of 100 V. This means it can safely block up to 75 V continuously across its terminals in normal operation, with breakdown occurring no earlier than 100 V under specified test conditions. Designers must ensure applied reverse voltages remain below VRWM to avoid premature failure.
Is JANTXV1N6642 RoHS compliant?
No, JANTXV1N6642 is not RoHS compliant. Per the original Microsemi documentation, RoHS-compliant versions (e3 suffix) were offered only for commercial-grade variants of the 1N66xx series. The JANTXV prefix denotes military-qualified units with tin-lead plated leads, which fall outside RoHS exemption scope.
What does the "JANTXV" prefix indicate for JANTXV1N6642?
The "JANTXV" prefix identifies JANTXV1N6642 as qualified to Level V per MIL-PRF-19500/578 - the highest screening tier for discrete semiconductors, including 100% lot testing, burn-in, and rigorous environmental stress screening. It confirms full traceability, extended temperature validation, and guaranteed reliability for flight and ground-based defense systems.
Can JANTXV1N6642 replace 1N4148 in existing designs?
JANTXV1N6642 is explicitly listed as a replacement for 1N4148 in the manufacturer's documentation, offering superior thermal range (–65 °C to +175 °C vs. –65 °C to +175 °C), tighter trr consistency, and hermetic reliability. However, its axial "D" package differs mechanically from DO-35, so board layout and soldering processes must be validated prior to substitution.
What is the thermal resistance from junction to ambient for JANTXV1N6642?
The junction-to-ambient thermal resistance (RθJA) for JANTXV1N6642 is 250 °C/W under defined PCB conditions: FR4 board, 1-layer 1-oz copper, horizontal orientation, still air, and 0.375-inch lead length. This value assumes standard axial mounting and is used to calculate junction temperature rise under steady-state load conditions.
