Product details
Overview
1N5653A/TR from Microchip Technology is a unidirectional transient voltage suppressor (TVS) diode in a hermetically sealed DO-13 metal package, designed for high-reliability surge protection in aerospace and industrial systems. It features a 55.1 V rated standoff voltage (VWM), 61.2–74.8 V breakdown voltage (V(BR)), 98.0 V maximum clamping voltage (VC) at 15.3 A peak pulse current, and 1500 W peak pulse power rating per 10/1000 µs waveform.
For engineers reviewing the 1N5653A/TR datasheet, 1N5653A/TR pinout, 1N5653A/TR application, or 1N5653A/TR equivalent, this device is selected for secondary lightning protection (IEC61000-4-5 Class 1–4), ESD/EFT immunity (IEC61000-4-2/-4), and inductive switching transient suppression where sub-100 ps response and radiation-hardened operation are required.
Technical Context
The 1N5653A/TR operates as a unidirectional avalanche diode, entering controlled breakdown when transient voltage exceeds its V(BR) threshold to clamp downstream circuitry. Its DO-13 metal-glass package provides hermetic sealing and inherent radiation hardness per MicroNote 050, supporting operation from –55°C to +175°C.
It delivers 1500 W non-repetitive peak pulse power with <100 ps response time and exhibits a temperature coefficient of breakdown voltage (αV(BR)) of 0.104 %/°C. Standby leakage current is ≤5 µA at 55.1 V VWM, and thermal resistance is 50°C/W junction-to-lead at 10 mm lead length.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression 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 PPP rating. | Requires PCB redesign for SMT layout; lacks hermetic seal and radiation hardness. | Select when board space is constrained and military environmental specs are not required. |
| 1N5653A (bulk) | Identical electrical specs and DO-13 package; differs only in packaging format (tape-and-reel vs. bulk). | No functional or application difference; TR suffix denotes EIA-296 tape-and-reel delivery. | Choose 1N5653A/TR for automated assembly; choose 1N5653A for manual prototyping or low-volume hand-soldering. |

FAQ
What is the standoff voltage (VWM) of the 1N5653A/TR?
The 1N5653A/TR has a rated standoff voltage (VWM) of 55.1 V, meaning it remains non-conductive up to this reverse DC voltage level. This value is selected to exceed typical 48 V or 54 V system rails while maintaining sufficient margin below the 61.2 V minimum breakdown voltage (V(BR)). The 1N5653A/TR's VWM ensures reliable blocking during normal operation while enabling fast avalanche conduction during transients.
Does the 1N5653A/TR meet IEC61000-4-5 for secondary lightning protection?
Yes, the 1N5653A/TR is explicitly rated for secondary lightning protection per IEC61000-4-5 across multiple source impedances: Class 1–4 with 42 Ω, Class 1–4 with 12 Ω, and Class 2–3 with 2 Ω. Its 1500 W peak pulse power and 98.0 V clamping voltage at 15.3 A ensure compliant energy diversion without overstressing downstream circuitry. The 1N5653A/TR's performance is validated in the official T4-LDS-0096 datasheet.
Is the 1N5653A/TR radiation hardened?
Yes, the 1N5653A/TR is inherently radiation hard per Microsemi MicroNote 050, a result of its hermetically sealed DO-13 metal-glass construction and silicon process. This makes the 1N5653A/TR suitable for space-qualified electronics, nuclear instrumentation, and high-altitude avionics where total ionizing dose (TID) and single-event effects (SEE) resistance are essential. Radiation hardness is a built-in property-not an optional qualification-of the 1N5653A/TR.
What is the thermal resistance of the 1N5653A/TR?
The 1N5653A/TR has a thermal resistance of 50°C/W junction-to-lead when measured at 10 mm (0.375 inch) from the package body, and 110°C/W junction-to-ambient when mounted on an FR4 PCB with 4 mm² copper pads and 1 mm wide × 25 mm long traces. This low junction-to-lead Rθ enables efficient heat dissipation during repetitive surge events and supports operation up to +175°C junction temperature. The 1N5653A/TR's thermal performance is documented in the "Maximum Ratings" section of its datasheet.
How does the "TR" suffix affect the 1N5653A/TR's specifications?
The "TR" suffix on 1N5653A/TR indicates EIA-296 standard tape-and-reel packaging for automated SMT placement-it does not alter any electrical, thermal, or mechanical specification of the 1N5653A/TR. The underlying device remains identical to the bulk 1N5653A: same DO-13 package, same VWM (55.1 V), same V(BR) range (61.2–74.8 V), and same 1500 W pulse rating. The 1N5653A/TR is fully interchangeable electrically and functionally with 1N5653A.
