Product details
Overview
JAN1N4454-1 from Central Semiconductor (CDI) is a hermetically sealed, metallurgically bonded switching diode in a DO-35 glass package with tin/lead-plated copper-clad steel leads, rated for 200 mA DC forward current, 75 V peak reverse voltage, and 4 ns reverse recovery time - used in high-reliability military timing, pulse shaping, and sample-and-hold circuits.
For engineers reviewing the JAN1N4454-1 datasheet, JAN1N4454-1 pinout, JAN1N4454-1 application, or JAN1N4454-1 equivalent, key selection criteria include its MIL-PRF-19500/144 qualification, -55°C to +175°C junction temperature range, 250°C/W junction-to-lead thermal resistance, and low 0.7 V forward voltage at 10 mA - critical for low-power, high-temperature analog signal routing.
Technical Context
The JAN1N4454-1 employs double-plug construction and metallurgical bonding to achieve stable switching performance across extreme temperatures. Its 4 ns reverse recovery time and 200 mA operating current support fast edge transitions in precision waveform generation and clamping.
Rated for 75 V peak reverse voltage and 50 V RMS reverse working voltage, it maintains leakage below 0.1 µA at 50 V dc and 100 µA at 50 V (TA = 150°C), enabling reliable operation in high-impedance bias networks and radiation-tolerant analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Voltage (VF) | 0.7 V @ IF = 10 mA - enables low-loss biasing in low-voltage analog signal paths |
| Peak Reverse Voltage (VRWM) | 50 V dc - defines maximum continuous reverse bias in clamp or protection circuits |
| Peak Repetitive Reverse Voltage (VRRM) | 75 V - sets safe margin for transient voltage spikes in pulse applications |
| Reverse Recovery Time (trr) | 4 ns - supports >100 MHz switching in RF sampling and high-speed logic interfaces |
| Junction-to-Lead Thermal Resistance (RθJL) | 250 °C/W max @ L = 0.375 in - constrains power dissipation in hermetic lead-frame mounting |
| Capacitance @ 0 V | 2.0 pF - minimizes loading on high-frequency signal nodes and clock distribution lines |
| Reverse Leakage (IR1) | 0.1 µA @ 50 V dc, 25°C - ensures stability in precision reference and feedback networks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JAN1N4148-1 | Higher trr (4–6 ns typical), same DO-35 package, 100 V VRRM, but only JANTX-rated (not JANTXV) | Less suitable for >100 MHz pulse applications requiring guaranteed 4 ns max trr | Acceptable where full JANTXV screening and 75 V rating are not required |
| JANTXV1N4454 | Identical electrical specs and construction; differs only in MIL-STD-883 test flow and lot documentation depth | No functional difference; used interchangeably where procurement mandates JANTXV-level test reporting | Select when contract requires JANTXV certification traceability, not just performance equivalence |
Compared with JAN1N4454-1, JAN1N4148-1 offers higher reverse voltage but lacks JANTXV screening and guaranteed 4 ns trr; JANTXV1N4454 matches all parameters exactly but incurs additional test documentation overhead for qualified programs.

FAQ
What is the maximum junction temperature rating for the JAN1N4454-1?
The JAN1N4454-1 has a maximum junction temperature rating of +175°C and a minimum of -55°C, verified per MIL-PRF-19500/144. This allows uninterrupted operation in engine bay electronics and downhole tools where ambient temperatures exceed 125°C. The JAN1N4454-1 maintains specified leakage and switching performance across this full range without derating until 25°C ambient.
Is the JAN1N4454-1 pin-compatible with standard DO-35 switching diodes like the 1N4148?
Yes, the JAN1N4454-1 uses the DO-35 axial package with identical lead spacing and dimensions, making it physically interchangeable with 1N4148-family diodes on PCBs. However, the JAN1N4454-1 is screened to JANTXV level and specified for 75 V VRRM, whereas commercial 1N4148 variants are typically rated at 100 V but lack military screening. The JAN1N4454-1 must be substituted with attention to voltage and reliability requirements.
What does the "-1" suffix indicate in JAN1N4454-1?
The "-1" suffix in JAN1N4454-1 denotes compliance with the specific outline and test requirements defined in MIL-S-19500/144, including double-plug construction, metallurgical bonding, and hermetic glass sealing. It distinguishes this variant from non-compliant commercial equivalents and confirms adherence to the full JANTXV screening flow. The JAN1N4454-1 is not a revision or package variant - it is the qualified baseline configuration.
How does the JAN1N4454-1 perform at elevated temperature?
At TA = 150°C, the JAN1N4454-1 exhibits reverse leakage of 100 µA at 50 V and maintains forward voltage of 0.7 V at 10 mA - matching room-temperature values within tolerance. Its 250°C/W RθJL and metallurgically bonded die ensure predictable thermal behavior in conduction-cooled modules. The JAN1N4454-1 is characterized across temperature in Figures 2 and 3 of its official datasheet.
Can the JAN1N4454-1 be used in RF detector applications?
Yes, the JAN1N4454-1 is suitable for RF detection up to ~500 MHz due to its 2.0 pF junction capacitance, 4 ns reverse recovery time, and low 0.7 V forward voltage - enabling efficient envelope detection in L-band receivers and radar warning systems. Its hermetic DO-35 package prevents parameter shift under humidity exposure, a key requirement for field-deployed RF front-ends using the JAN1N4454-1.
