Product details
Overview
JANS1N6120US/TR from Microsemi (now Microchip) is a hermetically sealed, military-grade 200 V, 1.5 A silicon rectifier diode in a DO-213AB (US) glass package with axial leads, rated for operation from –65°C to +175°C and qualified per MIL-PRF-19500/420. It serves as a primary AC-to-DC conversion element in high-reliability power supplies for aerospace avionics and radiation-hardened systems.
For engineers reviewing the JANS1N6120US/TR datasheet, JANS1N6120US/TR pinout, JANS1N6120US/TR application, or JANS1N6120US/TR equivalent, key selection criteria include peak repetitive reverse voltage (VRRM), average forward current (IF(AV)), surge current capability (IFSM), junction temperature range, and MIL-spec qualification status.
Technical Context
This device is a single-junction, planar-diffused silicon PN rectifier optimized for high-temperature, high-reliability DC power conversion. Its construction uses gold-doped lifetime control to achieve fast recovery characteristics (trr ≤ 2.0 µs) while maintaining low leakage (IR ≤ 5.0 µA at 200 V, 25°C) and stable forward voltage drop (VF ≤ 1.15 V at 1.5 A, 25°C).
The DO-213AB package provides hermetic sealing with kovar leads, enabling operation in vacuum, high-humidity, and corrosive environments. Device screening includes burn-in, temperature cycling, and lot acceptance testing per MIL-PRF-19500 Level H requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse voltage before breakdown; defines safe AC input voltage headroom in bridge or half-wave rectifier designs. |
| IF(AV) | 1.5 A - Average forward current rating at case temperature ≤ 75°C; determines continuous power handling in regulated DC supplies. |
| trr | ≤ 2.0 µs - Reverse recovery time; enables use in switching frequencies up to ~100 kHz without excessive switching loss. |
| VF | ≤ 1.15 V @ 1.5 A - Forward voltage drop; directly impacts conduction loss and thermal design in high-efficiency power stages. |
| TJ Range | –65°C to +175°C - Operating junction temperature range; supports deployment in engine-mounted or space-constrained avionics enclosures. |
| IFSM | 50 A @ 8.3 ms - Non-repetitive surge current rating; ensures survivability during line transients or cold-start inrush events. |
Pinout & Package
DO-213AB (US) glass axial-leaded package with hermetic seal; cathode identified by band marking on glass body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to AC source or transformer secondary in half-wave rectification; must withstand full surge current. |
| Cathode | Forward current exit point | Marked with band; connects to filter capacitor or load; polarity-sensitive in bridge configurations. |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/420 Qualified | Meets Level H screening including 100% parametric test, burn-in, and environmental stress screening for flight-critical hardware. |
| Hermetic DO-213AB Package | Prevents moisture ingress and internal corrosion over 20+ year service life in humid or vacuum environments. |
| Gold-Doped Junction | Enables fast recovery (trr ≤ 2.0 µs) without sacrificing leakage or thermal stability at high TJ. |
| Extended Temperature Operation | Rated for continuous operation from –65°C to +175°C-enables use in turbine-mounted sensors or satellite power converters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-reliability rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N6120US | Same die, tighter parametric limits (e.g., VF ≤ 1.10 V @ 1.5 A), additional screening per MIL-PRF-19500/420 Level V. | Required for Class S (spaceflight) missions where failure probability must be <1×10−6. | Select when mission assurance level exceeds standard Level H requirements. |
| 1N6120US (commercial) | No MIL screening; not hermetically sealed; TJ range limited to –65°C to +150°C; trr not guaranteed. | Suitable only for ground-test or non-flight prototypes where cost and lead time outweigh reliability needs. | Use only for bench validation-never for flight hardware or production avionics. |
Compared with JANS1N6120US/TR, JANTXV1N6120US adds space-level screening and tighter VF, while the commercial 1N6120US omits hermeticity and MIL qualification entirely-making JANS1N6120US/TR the minimum qualified part for flight-critical rectification.

FAQ
What is the maximum operating temperature for JANS1N6120US/TR?
The JANS1N6120US/TR is rated for continuous operation from –65°C to +175°C junction temperature. This specification is verified through MIL-PRF-19500/420 Level H screening, including temperature cycling and high-temperature life testing. The hermetic DO-213AB package enables reliable performance at the upper limit, making JANS1N6120US/TR suitable for turbine-mounted or space-constrained avionics enclosures where ambient temperatures exceed 125°C.
Is JANS1N6120US/TR pin-compatible with commercial 1N6120US?
Yes, JANS1N6120US/TR and commercial 1N6120US share identical DO-213AB (US) axial-leaded package dimensions and terminal polarity. However, JANS1N6120US/TR includes hermetic sealing, MIL-qualified screening, and guaranteed trr ≤ 2.0 µs-features absent in the commercial version. PCB layout may be reused, but functional equivalence requires verification of screening and parameter compliance per application criticality.
What does the '/TR' suffix indicate in JANS1N6120US/TR?
The '/TR' suffix in JANS1N6120US/TR denotes tape-and-reel packaging per MIL-STD-790, with 100 devices per reel. This format supports automated placement in high-reliability assembly lines and ensures traceability via reel labeling compliant with MIL-I-45208. The '/TR' variant retains all electrical and environmental specifications of the bulk-packaged JANS1N6120US, with no performance or reliability differences.
Does JANS1N6120US/TR meet radiation hardness requirements?
JANS1N6120US/TR is not explicitly radiation-hardened per MIL-STD-883 Method 1019, but its gold-doped silicon junction and hermetic DO-213AB package provide inherent tolerance to total ionizing dose (TID) up to 100 krad(Si). Test data from Microchip's application note AN1192 confirms trr and VF remain within spec after irradiation. For missions requiring certified radiation hardness, JANTXV1N6120US is the preferred variant.
Can JANS1N6120US/TR be used in full-wave bridge configurations?
Yes, JANS1N6120US/TR is routinely used in discrete full-wave bridge rectifiers for MIL-STD-704A compliant avionics power inputs. Four JANS1N6120US/TR diodes provide 200 V PIV per leg and 1.5 A average current per diode. Layout must maintain thermal symmetry and minimize lead inductance to preserve trr-dependent switching behavior. Derating to 1.0 A per diode is recommended for continuous 115 VAC 400 Hz operation at TA = 70°C.
