Product details
Overview
JANTX1N5711UBCA/TR from Microsemi is a military-qualified ceramic surface-mount Schottky barrier diode with common-anode polarity, 70 V breakdown voltage, 1.0 V forward voltage at 15 mA, and 50 V working peak reverse voltage-used in high-reliability RF detector and sample-and-hold circuits.
For engineers reviewing the JANTX1N5711UBCA/TR datasheet, JANTX1N5711UBCA/TR pinout, JANTX1N5711UBCA/TR application, or JANTX1N5711UBCA/TR equivalent, key selection criteria include low reverse leakage (200 nA @ 50 V), fast switching (100 ps minority carrier lifetime), ceramic package thermal resistance (100 °C/W), and MIL-PRF-19500/444 JANTX-level qualification for aerospace and defense systems.
Technical Context
This device implements a unidirectional Schottky junction optimized for low-loss signal rectification in high-frequency analog front-ends. Its 100 ps effective minority carrier lifetime enables sub-nanosecond recovery, while the ceramic-encapsulated UB package ensures stable operation across -65 °C to +150 °C junction temperature range.
The common-anode (CA) configuration supports dual-diode functions in compact layouts, and gold-plated nickel terminals provide reliable solderability under MIL-STD-202 test conditions. Reverse leakage remains ≤200 nA at VR = 50 V, supporting precision DC restoration in low-power instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage V(BR) | 70 V minimum at 10 µA - ensures safe operation up to 70 V transient spikes without avalanche conduction |
| Forward Voltage VF | 1.0 V max at IF = 15 mA - minimizes power loss and self-heating in low-current detection paths |
| Working Peak Reverse Voltage VRWM | 50 V - defines maximum continuous reverse bias in AC-coupled signal chains |
| Reverse Leakage IR | 200 nA max at VR = 50 V - preserves signal integrity in high-impedance sampling nodes |
| Junction Temp Range | -65 °C to +150 °C - supports deployment in extended-temperature avionics and space-grade electronics |
| Thermal Resistance RθJSP | 100 °C/W - enables direct thermal coupling to PCB copper for passive cooling in sealed enclosures |
| Minority Carrier Lifetime τ | 100 ps - guarantees fast turn-off for RF envelope detection above 100 MHz |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5711UB-TR | Same electrical specs and UB package; commercial-grade (no MIL qualification) | Lacks JANTX screening-unsuitable for flight hardware but acceptable for ground-test prototypes | Select when cost-sensitive development requires identical form/function without military screening |
| SM1N5711-CA | Surface-mount Schottky with CA polarity; 70 V V(BR), but rated only to +125 °C junction temp | Not qualified to MIL-PRF-19500; limited to industrial-grade avionics subsystems | Choose for non-flight-critical modules where extended temperature range is not required |
Compared with JANTX1N5711UBCA/TR, the 1N5711UB-TR offers identical performance at lower cost but no reliability screening, while SM1N5711-CA provides similar CA functionality with reduced thermal margin-making JANTX1N5711UBCA/TR the sole choice for full-spectrum aerospace deployment.

FAQ
What is the maximum average rectified current for JANTX1N5711UBCA/TR?
The JANTX1N5711UBCA/TR has a maximum average rectified output current (IO) of 33 mA at 25 °C ambient. This derates linearly to zero at +150 °C junction temperature when the external case and solder pad temperatures reach +140 °C, per the datasheet's thermal derating curve. The 33 mA rating reflects its use in low-power RF detection-not power conversion.
Is JANTX1N5711UBCA/TR RoHS compliant?
Yes, JANTX1N5711UBCA/TR is RoHS compliant by design, containing no lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE). Compliance is verified per EU Directive 2011/65/EU and aligns with DoD Directive 4140.01 for environmentally preferable procurement.
What does the "CA" suffix mean in JANTX1N5711UBCA/TR?
The "CA" in JANTX1N5711UBCA/TR stands for Common Anode-a dual-diode configuration where both anodes are internally connected and brought out to Pad 1. Cathodes are isolated on Pads 2 and 3, enabling independent signal paths sharing one anode node-ideal for balanced detector or dual-channel sampling circuits.
Can JANTX1N5711UBCA/TR replace standard 1N5711 in existing designs?
JANTX1N5711UBCA/TR is not a drop-in replacement for through-hole 1N5711-1 (DO-35) due to different package (UB vs DO-35), pinout, and thermal path. However, it matches the 1N5711's electrical specs and serves as the surface-mount, military-qualified equivalent-requiring PCB layout revision but no circuit redesign.
What is the reverse recovery time of JANTX1N5711UBCA/TR?
JANTX1N5711UBCA/TR does not specify trr in its datasheet because Schottky diodes are majority-carrier devices with no minority-carrier storage delay. Instead, its 100 ps effective minority carrier lifetime (τ) governs switching speed-enabling clean turn-off in RF detector applications up to several hundred MHz without reverse recovery overshoot.
