Product details
Overview
1N5711UBD/TR from Microsemi is a ceramic-surface-mount Schottky barrier diode qualified to MIL-PRF-19500/444 at JAN/JANTXV levels, with 70 V breakdown voltage, 50 V working peak reverse voltage, and 200 nA max reverse leakage at 50 V, used in high-reliability RF detector and sample-and-hold circuits.
For engineers reviewing the 1N5711UBD/TR datasheet, 1N5711UBD/TR pinout, 1N5711UBD/TR application, or 1N5711UBD/TR equivalent, key selection criteria include military-grade temperature range (–65°C to +150°C), low-profile ceramic package, sub-1 V forward drop at 15 mA, and ESD sensitivity Class 1 handling requirements.
Technical Context
This device implements a unidirectional Schottky junction optimized for low-noise, high-speed switching in signal demodulation and clamping. Its 100 ps minority carrier lifetime and 2.0 pF capacitance at 0 V enable operation up to UHF frequencies without significant phase distortion.
Thermal resistance of 100°C/W from junction to solder pad supports stable performance under pulsed current conditions in compact layouts. The gold-plated nickel terminals ensure reliable interconnect integrity across thermal cycling in aerospace and defense systems.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5711UR-1 | Same electrical specs but DO-213AA plastic package; no MIL qualification | Lacks hermeticity and temperature range - unsuitable for vacuum or extended-temp military use | Select only for commercial-grade cost-sensitive designs where MIL screening is not required |
| SMCJ5.0A | TVS diode with 5.0 V standoff; not a Schottky rectifier - different function and failure mode | Used for surge suppression, not signal detection or clamping - incompatible circuit role | Not interchangeable; choose only if transient protection-not low-VF rectification-is the design goal |
Compared with 1N5711UBD/TR, 1N5711UR-1 offers identical electrical behavior but lacks military reliability validation and hermetic packaging, while SMCJ5.0A serves a fundamentally different protection function and cannot replace the Schottky's signal-path role.

FAQ
What is the maximum average forward current rating for 1N5711UBD/TR?
The 1N5711UBD/TR has a maximum average rectified output current (IO) of 33 mA at 25°C. Derating applies above +140°C ambient: IO decreases linearly to zero at +150°C. This rating assumes full-wave 50/60 Hz sine-wave input with 180° conduction angle and proper thermal management via the solder pad.
Is 1N5711UBD/TR RoHS compliant?
Yes, the 1N5711UBD/TR is RoHS compliant by design per the manufacturer's documentation. It contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE), meeting EU Directive 2011/65/EU requirements for hazardous substances.
What does the "UB" suffix indicate in 1N5711UBD/TR?
The "UB" suffix denotes the ceramic surface-mount package variant qualified to MIL-PRF-19500/444. It distinguishes this version from axial DO-35 ("1N5711-1") and plastic surface-mount DO-213AA ("1N5711UR-1") variants. The "D" indicates tape-and-reel packaging per EIA-418D standards.
Can 1N5711UBD/TR be used as a direct replacement for 1N5711-1 in existing designs?
No - 1N5711UBD/TR uses a ceramic surface-mount UB package, while 1N5711-1 is axial-leaded DO-35. Physical form factor, thermal path, and PCB layout are incompatible. Electrical parameters match, but mechanical integration requires redesign. Use only when migrating to surface-mount assembly with verified thermal and mechanical validation.
What is the reverse recovery time (trr) specification for 1N5711UBD/TR?
The 1N5711UBD/TR does not specify trr in its datasheet because Schottky diodes are majority-carrier devices with no minority-carrier storage delay. Instead, its effective switching speed is characterized by a 100 ps minority carrier lifetime (τ), enabling nanosecond-scale turn-off behavior suitable for RF and high-speed digital clamping applications.
