Product details
Overview
1N5652A/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 50.2 V rated standoff voltage (VWM), 58.9 V minimum breakdown voltage (V(BR)), 85.0 V maximum clamping voltage (VC) at 17.7 A peak pulse current (IPP), and 1500 W peak pulse power rating per 10/1000 µs waveform.
For engineers reviewing the 1N5652A/TR datasheet, 1N5652A/TR pinout, 1N5652A/TR application, or 1N5652A/TR equivalent, this device is selected for secondary lightning protection per IEC61000-4-5 (with 42 Ω, 12 Ω, or 2 Ω source impedance), ESD/EFT immunity per IEC61000-4-2/-4-4, and fast-clamp (<100 ps) protection of sensitive analog/digital interfaces in avionics and ruggedized electronics.
Technical Context
The 1N5652A/TR operates as a unidirectional avalanche diode, entering controlled breakdown when transient voltage exceeds its 50.2 V standoff level to clamp downstream circuitry. Its hermetic DO-13 package ensures stable performance across -55°C to +175°C operating temperature range and inherent radiation hardness per MicroNote 050.
It delivers 1500 W peak pulse power handling with <100 ps response time and thermal resistance of 50°C/W junction-to-lead, enabling robust protection against inductive switching transients, induced RF, and secondary lightning surges without derating concerns at lead temperature ≤125°C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5652A | No tape-and-reel packaging; bulk or ammo pack only. | Lacks TR suffix; not optimized for automated SMT placement. | Select 1N5652A/TR when requiring reel-fed pick-and-place assembly in high-volume production. |
| SMBJ58A | Surface-mount SMB package; 58 V VWM; 93.6 V VC @ 16.0 A; lower thermal resistance (junction-to-ambient). | Better suited for space-constrained PCBs but lacks hermetic sealing and radiation hardness. | Choose SMBJ58A where board area is critical and environmental stressors are less severe than avionics-grade requirements. |
Compared with 1N5652A/TR, the 1N5652A requires manual or bulk loading and offers identical electrical specs but no reel convenience, while SMBJ58A trades hermetic reliability and high-temp operation for compactness and higher volume manufacturability-making 1N5652A/TR optimal for mission-critical through-hole deployments.

FAQ
What is the clamping voltage of the 1N5652A/TR under a standard 10/1000 µs surge?
The 1N5652A/TR has a maximum clamping voltage (VC) of 85.0 V when subjected to its rated peak pulse current of 17.7 A under the 10/1000 µs waveform. This value is measured at 25°C and defines the upper voltage limit imposed on protected circuitry during surge events. The 1N5652A/TR maintains this clamping performance across its full operating temperature range due to its stable avalanche characteristics and hermetic packaging.
Is the 1N5652A/TR suitable for IEC61000-4-5 secondary lightning protection?
Yes, the 1N5652A/TR is explicitly rated for secondary lightning protection per IEC61000-4-5 with 42 Ω, 12 Ω, and 2 Ω source impedances-supporting Class 1 through Class 4 depending on impedance configuration. Its 1500 W peak pulse power and 85.0 V clamping voltage enable compliance with system-level surge immunity requirements in avionics and industrial control applications. The 1N5652A/TR achieves this without derating up to +125°C lead temperature.
How does the DO-13 package of the 1N5652A/TR improve reliability versus plastic alternatives?
The DO-13 package of the 1N5652A/TR is a welded, hermetically sealed metal-glass construction that prevents moisture ingress, eliminates delamination risks, and ensures stable electrical parameters under thermal cycling and high-humidity conditions. Unlike plastic axial-leaded equivalents, the 1N5652A/TR's DO-13 package provides inherent radiation hardness per MicroNote 050 and supports operation from -55°C to +175°C without parameter drift-critical for aerospace and downhole electronics.
What is the standoff voltage rating of the 1N5652A/TR, and how should it be applied in circuit design?
The 1N5652A/TR has a rated standoff voltage (VWM) of 50.2 V, meaning it remains non-conductive below this reverse voltage level during normal operation. Circuit designers must ensure the DC or continuous peak operating voltage of the protected line does not exceed 50.2 V to avoid leakage current or premature conduction. The 1N5652A/TR is intended for use on DC-biased lines where overvoltage events are infrequent but potentially destructive.
Does the "TR" suffix in 1N5652A/TR indicate any electrical differences from the base 1N5652A part?
No, the "TR" suffix in 1N5652A/TR denotes tape-and-reel packaging per EIA-296 standard and introduces no electrical or parametric differences from the 1N5652A. Both share identical breakdown voltage (58.9–65.1 V), clamping voltage (85.0 V), peak pulse power (1500 W), and thermal specifications. The 1N5652A/TR is optimized for automated assembly, while the 1N5652A is supplied in bulk or ammo pack formats.
