Product details
Overview
JAN1N5648A from Microchip Technology is a hermetically sealed, unidirectional transient voltage suppressor (TVS) diode in DO-13 metal package, designed for high-reliability aerospace and military systems. It features a 34.8 V rated standoff voltage (VWM), 40.9 V minimum breakdown voltage (V(BR)) at 1 mA, and clamps transients to ≤59.3 V at 25.3 A peak pulse current (IPP), delivering 1500 W peak pulse power per 10/1000 µs waveform.
For engineers reviewing the JAN1N5648A datasheet, JAN1N5648A pinout, JAN1N5648A application, or JAN1N5648A equivalent, this part serves as a Class 4 secondary lightning protection device per IEC61000-4-5 with 42 Ω source impedance, supports ESD/EFT immunity per IEC61000-4-2/-4, and operates across -55°C to +175°C for avionics and harsh-environment power rail protection.
Technical Context
The JAN1N5648A functions as a unidirectional avalanche-clamping TVS diode, activated only under reverse-biased overvoltage conditions above its 34.8 V standoff threshold. Its response time is under 100 ps, enabling suppression of fast-rising ESD events and switching transients before downstream circuitry sustains damage.
It exhibits a positive temperature coefficient of breakdown voltage (αV(BR) = 0.101 %/°C), ensuring stable clamping performance across its full operating range. The DO-13 metal-glass hermetic package provides radiation hardness per MicroNote 050 and supports lead temperature up to +125°C with 1 W DC power dissipation derating.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N5648A | Same electrical specs; tighter parametric tolerances and extended screening per MIL-PRF-19500/500 JANTXV level. | Required for Class H (high reliability) space programs and critical flight-critical subsystems. | Select when full JANTXV qualification (including burn-in and lot acceptance testing) is mandated by program spec. |
| 1N5648A (commercial) | Identical VWM, V(BR), VC, and package; lacks military screening, traceability, and radiation validation. | Suitable for ground-based test equipment or non-flight prototypes where cost and lead time outweigh qualification needs. | Choose for development boards or non-mission-critical subsystems where JAN-level reliability is not required. |
Compared with JANTXV1N5648A, the JAN1N5648A offers verified military screening but less rigorous environmental stress testing; versus 1N5648A, it guarantees traceable sourcing, lot-level documentation, and radiation hardness-making it the baseline qualified choice for flight hardware.

FAQ
What is the standoff voltage (VWM) specification for JAN1N5648A?
The JAN1N5648A has a rated standoff voltage (VWM) of 34.8 V, meaning it remains non-conductive under continuous reverse bias up to this level. This value is selected to provide adequate margin above standard 28 V aircraft bus nominal voltage while avoiding false triggering during routine transients like engine start-up spikes. The VWM is confirmed in the Electrical Characteristics table on page 3 of the T4-LDS-0096 Rev. 3 datasheet.
Does JAN1N5648A meet IEC61000-4-5 Class 4 lightning surge requirements?
Yes, JAN1N5648A is explicitly rated for Class 4 secondary lightning protection per IEC61000-4-5 with a 42 Ω source impedance, as stated in the Applications/Benefits section on page 2 of the datasheet. Its 1500 W peak pulse power and 59.3 V clamping voltage at 25.3 A ensure compliance when properly mounted with low-inductance grounding on 28 V systems.
What is the package type and mounting configuration for JAN1N5648A?
JAN1N5648A uses the DO-13 (DO-202AA) hermetically sealed metal-glass package with axial leads. The cathode is connected to the metal case and marked by a diode symbol on the body; Lead 1 (cathode/case) must be tied to the protected line, and Lead 2 (anode) to system ground. Full mechanical dimensions are provided on page 6 of the T4-LDS-0096 datasheet.
How does JAN1N5648A differ from commercial 1N5648A?
JAN1N5648A is the military-qualified version of 1N5648A, featuring full traceability, lot-level documentation, extended temperature screening (-55°C to +175°C), and radiation hardness validation per MicroNote 050. While both share identical electrical parameters (VWM = 34.8 V, VC = 59.3 V), only JAN1N5648A meets MIL-PRF-19500/500 requirements for flight-critical hardware.
What is the maximum clamping voltage (VC) and corresponding peak pulse current (IPP) for JAN1N5648A?
JAN1N5648A has a maximum clamping voltage (VC) of 59.3 V at a peak pulse current (IPP) of 25.3 A, measured under the standard 10/1000 µs double-exponential waveform. This VC/IPP pair defines the worst-case voltage imposed on protected circuitry during surge events and is validated in the Electrical Characteristics table on page 3 of the T4-LDS-0096 datasheet.
