Product details
Overview
JANTXV1N914UR/TR from Microsemi is a hermetically sealed glass MELF surface-mount switching diode qualified to MIL-PRF-19500/116 JANTXV level, featuring 5 ns reverse recovery time, 75 V working peak reverse voltage, and 200 mA average rectified current at 75°C - used in high-speed logic arrays, RS-232 interfaces, and Ethernet 10 Base-T transient protection.
For engineers reviewing the JANTXV1N914UR/TR datasheet, JANTXV1N914UR/TR pinout, JANTXV1N914UR/TR application, or JANTXV1N914UR/TR equivalent, key selection criteria include reverse recovery time, junction temperature range (–65°C to +175°C), low capacitance (2.8 pF at 1.5 V), RoHS-compliant plating options, and DO-213AA package compatibility with high-density SMT layouts.
Technical Context
This diode employs metallurgically bonded construction inside a hermetically sealed DO-213AA glass MELF case, enabling stable operation across –65°C to +175°C. Its double-plug termination ensures mechanical robustness and thermal reliability under surge conditions up to 2 A peak non-repetitive.
The device delivers fast switching performance via minimal charge storage: trr = 5 ns (IF = IR = 10 mA, RL = 100 Ω), VF1 = 0.8 V @ 10 mA, and low junction capacitance of 2.8 pF @ 1.5 V - critical for signal integrity in >10 MHz data paths and transient OR'ing circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Recovery Time (trr) | 5 ns - enables reliable operation in >10 MHz digital switching and pulse shaping circuits |
| Working Peak Reverse Voltage (VRWM) | 75 V - supports transient suppression in RS-232/RS-422 bus lines without clamping distortion |
| Average Rectified Current (IO) | 200 mA @ TA = 75°C - sufficient for logic-level steering and low-power signal routing |
| Junction Temperature Range | –65°C to +175°C - qualified for aerospace, defense, and downhole industrial environments |
| Junction Capacitance (C) | 2.8 pF @ VR = 1.5 V - minimizes signal loading on high-speed data lines like Ethernet 10 Base-T |
| Forward Voltage (VF1) | 0.8 V @ IF = 10 mA - reduces power loss in low-current bias and sensing applications |
| Thermal Resistance (RθJEC) | 100 °C/W - allows direct endcap heat transfer in constrained thermal layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4148W-7-F | Commercial-grade SOD-123; trr = 4 ns, VRWM = 100 V, C = 4 pF @ 0 V | Higher capacitance and no military qualification; suited for commercial consumer electronics only | Select when cost-sensitive, non-military designs require faster trr but tolerate higher C and wider tolerance bands |
| JANTXV1N4148UR-1 | Same DO-213AA package; trr = 4 ns, VRWM = 100 V, C = 4 pF @ 0 V, TJ = –65°C to +175°C | Higher breakdown rating and identical qualification level; slightly higher capacitance affects >20 MHz use cases | Choose for systems needing 100 V VRWM headroom while retaining JANTXV reliability and MELF form factor |
Compared with JANTXV1N914UR/TR, the 1N4148W-7-F offers marginally faster trr but lacks hermetic sealing and temperature range; JANTXV1N4148UR-1 matches qualification and package but trades 2.8 pF capacitance for higher VRWM - critical for transient-heavy vs. high-frequency signal integrity priorities.

FAQ
What is the maximum junction temperature rating for JANTXV1N914UR/TR?
JANTXV1N914UR/TR has a specified junction and storage temperature range of –65°C to +175°C, validated per MIL-PRF-19500/116 JANTXV qualification. This rating supports deployment in engine control units, satellite power systems, and downhole drilling electronics where thermal extremes are routine. The device maintains electrical stability across this full range when operated within its derated current limits.
Is JANTXV1N914UR/TR RoHS compliant?
JANTXV1N914UR/TR is not RoHS compliant - RoHS compliance (e3 marking) applies only to commercial-grade versions of the 1N914UR family. The JANTXV variant uses tin/lead plating per MIL-STD-750 method 2026 and is intended for applications where leaded terminations are required for solder joint reliability under thermal cycling stress.
What package type does JANTXV1N914UR/TR use?
JANTXV1N914UR/TR uses the DO-213AA glass MELF package: a hermetically sealed cylindrical body with double-plug axial terminations, cathode marked by a band, and dimensions of 1.60–1.70 mm diameter × 3.30–3.71 mm length. It is designed for surface-mount reflow assembly and provides superior thermal and mechanical reliability versus axial DO-35 variants.
How does the reverse recovery time of JANTXV1N914UR/TR compare to standard 1N4148 diodes?
JANTXV1N914UR/TR specifies trr = 5 ns under IF = IR = 10 mA, RL = 100 Ω - matching the performance tier of high-speed 1N4148 variants. While some commercial 1N4148 parts achieve 4 ns, JANTXV1N914UR/TR prioritizes consistency across temperature and radiation-hardened operation over marginal speed gains, making it preferred in deterministic timing-critical systems.
Can JANTXV1N914UR/TR replace JANTXV1N4148UR-1 in existing designs?
JANTXV1N914UR/TR is not a direct replacement for JANTXV1N4148UR-1 due to differences in VRWM (75 V vs. 100 V) and junction capacitance (2.8 pF vs. 4 pF). While both share DO-213AA packaging and JANTXV qualification, substitution requires verification of reverse voltage margin and high-frequency loading effects in the target circuit before implementation.
