Product details
Overview
1N5653A from Microchip Technology is a unidirectional transient voltage suppressor (TVS) diode in a hermetically sealed DO-13 metal package, designed for high-energy surge protection in aerospace, avionics, and industrial control systems. It features a 61.2 V minimum breakdown voltage (VBR), 55.1 V rated standoff voltage (VWM), 98.0 V maximum clamping voltage (VC) at 15.3 A peak pulse current (IPP), and 1500 W peak pulse power rating at 10/1000 µs waveform.
For engineers reviewing the 1N5653A datasheet, 1N5653A pinout, 1N5653A application, or 1N5653A equivalent, this device serves as a military-grade (JANTXV-qualified) through-hole TVS for secondary lightning protection per IEC 61000-4-5 (42 Ω, 12 Ω, and 2 Ω source impedances), ESD suppression per IEC 61000-4-2, and fast-response (<100 ps) protection against inductive switching transients.
Technical Context
The 1N5653A operates as a unidirectional avalanche diode with cathode connected to case, enabling robust reverse-biased transient clamping while maintaining low leakage (<5 µA at VWM). Its hermetic DO-13 package ensures reliability under extreme thermal (-55°C to +175°C) and radiation-hardened environments per MicroNote 050.
It delivers 1500 W non-repetitive peak pulse power at TL = 25°C with <100 ps response time, and supports forward surge current up to 200 A (8.3 ms half-sine). Thermal resistance is 50°C/W junction-to-lead (0.375" from body), enabling stable operation in high-power transient scenarios without derating below 125°C lead temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Rated Standoff Voltage) | 55.1 V - Maximum continuous reverse operating voltage before avalanche onset; sets system-level DC bias margin. |
| VBR (Breakdown Voltage @ IBR = 1 mA) | 61.2–71.4 V - Confirmed avalanche threshold range; defines minimum clamping trigger point. |
| VC (Clamping Voltage @ IPP = 15.3 A) | 98.0 V - Peak voltage seen by protected circuit during 10/1000 µs surge; determines downstream component stress. |
| IPP (Peak Pulse Current) | 15.3 A - Maximum transient current the device safely shunts without failure at specified waveform. |
| PPP (Peak Pulse Power) | 1500 W - Energy-handling capacity for single-event surges; enables Class 1–4 IEC 61000-4-5 compliance. |
| TJ/TL Range | -55°C to +175°C - Full military-grade operating and storage temperature envelope; supports avionics deployment. |
| Response Time | <100 ps - Near-instantaneous avalanche turn-on; critical for ESD/EFT immunity per IEC 61000-4-2/-4-4. |
Pinout & Package
Package: DO-13 (DO-202AA), hermetically sealed metal-glass case with tin-lead plated leads; cathode electrically tied to case; polarity marked by diode symbol on body; weight ≈1.4 g.

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMCJ58A | Surface-mount SMC package; 58 V VWM; 93.6 V VC @ 16.0 A; same 1500 W rating but lower thermal resistance (junction-to-ambient). | Requires PCB re-layout; better suited for automated assembly and space-constrained telecom modules. | Select when board space is limited and reflow compatibility is required; not drop-in for through-hole designs. |
| 1N5653 | Commercial-grade version; identical VWM, VBR, and VC specs but lacks JANTXV qualification and tighter parametric tolerances. | Approved only for non-military industrial use; excluded from aerospace or defense BOMs requiring MIL-PRF-19500 screening. | Choose for cost-sensitive commercial systems where radiation hardness and extended temperature validation are unnecessary. |
Compared with SMCJ58A and 1N5653, the 1N5653A uniquely combines hermetic DO-13 packaging, JANTXV qualification, and proven performance in airborne avionics-making it irreplaceable where military reliability, radiation tolerance, and through-hole mechanical robustness are mandatory.

FAQ
What is the standoff voltage (VWM) of the 1N5653A?
The 1N5653A has a rated standoff voltage (VWM) of 55.1 V, meaning it remains nonconductive under continuous reverse bias up to this level. This value is selected to exceed typical 48 V DC system operating voltages while providing sufficient margin before avalanche onset, ensuring reliable operation in avionics and industrial power buses where the 1N5653A is deployed.
Is the 1N5653A suitable for IEC 61000-4-5 secondary lightning protection?
Yes, the 1N5653A is explicitly validated for IEC 61000-4-5 secondary lightning protection across multiple classes: Class 1–4 with 42 Ω source impedance (up to 1N5648A), Class 1–3 with 12 Ω (up to 1N5643A), and Class 2–3 with 2 Ω (up to 1N5635A). Its 1500 W peak pulse rating and 98.0 V clamping voltage make the 1N5653A appropriate for protecting 48–60 V systems against standardized surge waveforms.
Does the 1N5653A have military qualification?
Yes, the "A" suffix in 1N5653A denotes compliance with MIL-PRF-19500/500 requirements for JANTXV-level screening, including extended temperature testing, hermeticity verification, and parametric tolerancing. This qualification confirms the 1N5653A's suitability for defense and aerospace applications where commercial-grade parts are prohibited.
What is the thermal resistance of the 1N5653A and how does it affect layout?
The 1N5653A has a junction-to-lead thermal resistance of 50°C/W when measured at 0.375 inches (10 mm) from the case body. This low thermal resistance allows efficient heat transfer to the PCB ground plane via the cathode-connected case, reducing reliance on large copper pours-critical for compact avionics layouts where the 1N5653A is often used in tight spaces near sensitive analog circuitry.
How does the 1N5653A differ from the commercial 1N5653 part?
The 1N5653A differs from the commercial 1N5653 by tighter parametric tolerances, full JANTXV qualification per MIL-PRF-19500/500, radiation hardness per MicroNote 050, and extended temperature validation from -55°C to +175°C. While both share identical electrical specs (VWM = 55.1 V, VC = 98.0 V), only the 1N5653A meets requirements for flight-critical systems where the 1N5653A is mandated.
