Product details
Overview
JAN1N5653A from Microchip Technology (formerly Microsemi) is a hermetically sealed, unidirectional transient voltage suppressor diode in DO-13 metal package, designed for high-reliability aerospace and military applications. It features 61.2 V minimum breakdown voltage (VBR), 55.1 V rated standoff voltage (VWM), and clamps transients to ≤98.0 V at 15.3 A peak pulse current (IPP) under 10/1000 µs waveform - delivering 1500 W peak pulse power for secondary lightning and ESD protection in avionics power rails.
For engineers reviewing the JAN1N5653A datasheet, JAN1N5653A pinout, JAN1N5653A application, or JAN1N5653A equivalent, this device serves as a MIL-PRF-19500/500 qualified TVS for critical DC power line protection where hermetic sealing, radiation hardness, and sub-100 ps response are mandatory - especially in airborne systems subject to IEC 61000-4-2, -4-4, and -4-5 surge classes.
Technical Context
The JAN1N5653A operates as a unidirectional avalanche diode, entering controlled breakdown above its 55.1 V standoff threshold to shunt surge energy away from protected circuitry. Its DO-13 metal-glass package provides hermetic sealing and inherent radiation hardness per MicroNote 050, enabling operation from –55 °C to +175 °C with 50 °C/W junction-to-lead thermal resistance.
It delivers 1500 W non-repetitive peak pulse power at 25 °C with 10/1000 µs waveform, clamping within <100 ps while maintaining ≤5 µA standby leakage at VWM. Temperature coefficient of VBR is +0.104 %/°C, supporting stable overvoltage protection across extended temperature ranges in harsh environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N5653A | Higher screening grade (JANTXV vs JAN); tighter VBR tolerance (±5% vs ±10%), enhanced lot traceability, and extended temperature validation to +175 °C. | Required for Class H (high reliability) space programs and DoD platforms demanding full JANTXV qualification per MIL-PRF-19500/500. | Select JANTXV1N5653A when full JANTXV screening, radiation test reports, and lot-specific conformance data are contractually mandated. |
| 1N5653A (commercial) | No military screening; not hermetically sealed; plastic DO-15 package; rated only to +150 °C; no radiation hardness documentation. | Suitable for industrial controls or non-safety-critical avionics prototypes where cost and availability outweigh environmental ruggedness. | Choose 1N5653A only for bench validation or non-mission-critical designs - never as drop-in replacement in JAN-qualified assemblies. |
Compared with JAN1N5653A, JANTXV1N5653A adds verified radiation tolerance and tighter parametric control for space-grade use, while 1N5653A sacrifices hermeticity and screening for lower cost and broader commercial availability - making JAN1N5653A the balanced choice for defense-grade ground and airborne systems requiring proven reliability without JANTXV overhead.

FAQ
What is the maximum clamping voltage of the JAN1N5653A under standard 10/1000 µs surge conditions?
The JAN1N5653A exhibits a maximum clamping voltage (VC) of 98.0 V when subjected to its rated 15.3 A peak pulse current (IPP) under the 10/1000 µs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuitry during transient events - critical for ensuring downstream ICs remain within absolute maximum ratings. The JAN1N5653A achieves this while maintaining ≤5 µA leakage at its 55.1 V standoff voltage.
Is the JAN1N5653A suitable for IEC 61000-4-5 secondary lightning protection?
Yes, the JAN1N5653A is explicitly rated for IEC 61000-4-5 secondary lightning protection across multiple classes: Class 1–4 with 42 Ω source impedance, Class 1–3 with 12 Ω, and Class 2–3 with 2 Ω. Its 1500 W peak pulse power and 98.0 V clamping enable compliant protection when implemented with appropriate PCB layout (e.g., short traces, thermal relief pads) and coordinated with upstream fusing. The JAN1N5653A's DO-13 package and hermetic seal further ensure reliability in the humid, high-vibration environments where IEC 61000-4-5 testing applies.
How does the JAN1N5653A differ from the commercial 1N5653A variant?
The JAN1N5653A differs from the commercial 1N5653A in three key ways: it uses a hermetically sealed DO-13 metal-glass package (vs. plastic DO-15), undergoes full MIL-PRF-19500/500 screening (including burn-in and temperature cycling), and is documented for radiation hardness per MicroNote 050. The JAN1N5653A also operates to +175 °C and guarantees ≤5 µA leakage at VWM, whereas the 1N5653A lacks these qualifications and environmental ratings - making the JAN1N5653A mandatory for defense and aerospace deployments.
What is the thermal resistance specification for the JAN1N5653A, and how does it impact layout design?
The JAN1N5653A has a junction-to-lead thermal resistance (RθJL) of 50 °C/W when measured at 10 mm from the case, per MIL-STD-750 Test Method 1071. This requires mounting the cathode (case) to a thermally conductive copper plane - ideally ≥4 mm² pad with 1 mm wide, 25 mm long traces - to achieve the rated 1500 W pulse capability. Without adequate heat sinking, pulse power derating occurs rapidly above 25 °C ambient, directly impacting surge survivability. The JAN1N5653A's DO-13 package design mandates mechanical attachment to a heatsink or chassis for sustained high-energy event handling.
Does the JAN1N5653A have polarity marking, and how is the cathode identified?
Yes, the JAN1N5653A features explicit polarity marking: a diode symbol is laser-etched or printed on the DO-13 metal case adjacent to lead 1, which is the cathode terminal. Per datasheet specification, the cathode is electrically connected to the metal case itself - meaning any mounting hardware or heatsink contacting the case becomes part of the cathode node. Lead 2 is the anode. This configuration requires careful PCB layout to avoid unintended shorting of the cathode to ground planes unless intentional, and mandates verification of case isolation when used in floating or dual-rail systems.
