Product details
Overview
1N5652/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, avionics, and industrial systems. It features a 50.2 V rated standoff voltage (VWM), 55.8 V minimum breakdown voltage (V(BR)), 89.0 V maximum clamping voltage (VC) at 16.9 A peak pulse current (IPP), and 1500 W peak pulse power rating at 10/1000 µs waveform.
For engineers reviewing the 1N5652/TR datasheet, 1N5652/TR pinout, 1N5652/TR application, or 1N5652/TR equivalent, this part delivers sub-100 ps response time, radiation-hardened performance per MicroNote 050, and IEC61000-4-2/4-4/4-5 compliance for ESD, EFT, and secondary lightning protection - critical for mission-critical power rail and signal line hardening.
Technical Context
The 1N5652/TR operates as a unidirectional avalanche clamp, triggered only under reverse-biased overvoltage conditions above its V(BR) threshold. Its DO-13 metal-glass package ensures low thermal resistance (50°C/W junction-to-lead) and stable operation from –55°C to +175°C, supporting high-temperature avionics and downhole equipment environments.
It exhibits a positive temperature coefficient of breakdown voltage (αV(BR) = 0.104 %/°C), enabling predictable voltage drift across temperature, and maintains <5 µA standby leakage (ID) at 50.2 V VWM - essential for low-power system monitoring circuits and battery-backed subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Rated Standoff Voltage) | 50.2 V - Maximum continuous reverse voltage before conduction; sets operating margin above 48 V DC rails. |
| V(BR) @ I(BR) | 55.8–58.9 V @ 1 mA - Confirmed avalanche onset range; ensures reliable triggering without premature conduction. |
| VC @ IPP | 89.0 V @ 16.9 A - Clamped voltage during 10/1000 µs surge; limits downstream IC stress to safe levels. |
| PPP (Peak Pulse Power) | 1500 W - Sustains high-energy transients (e.g., inductive switch-off, lightning-induced surges) without failure. |
| Response Time | <100 ps - Near-instantaneous clamping prevents nanosecond-scale voltage overshoot from damaging sensitive analog or digital inputs. |
| Operating Temperature | –55°C to +175°C - Validated for extreme environments including jet engine bays, space-grade enclosures, and oilfield electronics. |
| Package | DO-13 (DO-202AA) - Hermetic metal-glass construction with cathode-connected case; enables high-reliability through-hole mounting and superior moisture resistance. |
Pinout & Package
DO-13 (DO-202AA) hermetically sealed metal-glass package with axial leads. Cathode terminal is electrically connected to the metal case and marked by a diode symbol on the body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 2) | Current entry point during forward conduction | Used only for forward surge handling (200 A @ 8.3 ms); not active during normal TVS operation. |
| Cathode (Lead 1 / Case) | Clamping node and ground reference | Electrically tied to metal case; must be connected to system ground plane for effective transient shunting. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional clamping architecture | Protects only reverse-polarity transients while remaining invisible to normal forward-biased operation - ideal for DC power input lines. |
| Hermetic DO-13 metal package | Eliminates moisture ingress and long-term parameter drift; certified for MIL-PRF-19500/500 JANTXV qualification when ordered with "A" suffix. |
| IEC61000-4-5 secondary lightning compliance | Validated up to Class 4 (42 Ω source) for 1N5652A; enables drop-in use in DO-13 footprint designs requiring EN 61000-4-5 Level 4 immunity. |
| Radiation hardness | Inherently radiation-tolerant per Microsemi MicroNote 050 - suitable for low-earth orbit (LEO) satellite power conditioning and nuclear instrumentation. |
| Tape-and-reel packaging option | "TR" suffix denotes EIA-296 compliant tape-and-reel - supports automated through-hole insertion and traceable lot-controlled assembly. |
Applications
| Aerospace Power Distribution | Industrial Motor Drive Control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5652A/TR | Same electrical specs but tighter V(BR) tolerance (55.8–58.9 V vs. 55.8–58.9 V) and JANTXV qualification per MIL-PRF-19500/500. | Required for military/aerospace programs mandating screened, tested, and traceable components with extended temp validation. | Select 1N5652A/TR when full MIL-spec compliance and radiation testing documentation are contractually required. |
| SMCJ51A | Surface-mount SMC package; same 51 V VWM and 87.1 V VC @ 17.2 A, but lower 1.5 kW rating and plastic encapsulation. | Suitable for high-volume commercial PCBs where automated SMT placement is preferred and hermeticity is not mandated. | Choose SMCJ51A for cost-sensitive industrial controls where DO-13 mechanical robustness and hermetic sealing are nonessential. |
Compared with 1N5652/TR, the 1N5652A/TR adds military screening and traceability without altering electrical behavior, while SMCJ51A trades hermetic reliability and through-hole mechanical strength for SMT manufacturability and lower unit cost.

FAQ
What is the clamping voltage of the 1N5652/TR under a 10/1000 µs surge?
The 1N5652/TR has a maximum clamping voltage (VC) of 89.0 V when subjected to its rated peak pulse current of 16.9 A under the standard 10/1000 µs waveform. This value is guaranteed across temperature and represents the highest voltage seen across the device during transient suppression - critical for ensuring downstream components remain within their absolute maximum ratings.
Is the 1N5652/TR suitable for bidirectional transient protection?
No, the 1N5652/TR is a unidirectional TVS diode and conducts only in reverse breakdown. It does not protect against positive-going transients on grounded lines. For bidirectional protection in the same DO-13 package, Microchip specifies the 1N6036–1N6072A series - which are separate devices with symmetrical clamping characteristics.
Does the "TR" suffix in 1N5652/TR indicate tape-and-reel packaging?
Yes, the "TR" suffix explicitly denotes EIA-296 compliant tape-and-reel packaging for automated through-hole insertion. The 1N5652/TR is supplied in reels with standardized carrier tape pitch and cover tape specifications, enabling high-yield placement in production environments while maintaining full traceability per lot and date code.
What is the thermal resistance of the 1N5652/TR, and how does it affect layout?
The 1N5652/TR 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 RθJL enables efficient heat dissipation into the PCB copper pour or chassis ground plane - designers should maximize copper area connected to the cathode (case) and minimize lead length to preserve this thermal path during surge events.
Can the 1N5652/TR be used for primary lightning protection per IEC61000-4-5?
No, the 1N5652/TR is specified for secondary lightning protection per IEC61000-4-5 (e.g., induced surges in internal wiring). Its 1500 W rating and 89.0 V clamping are insufficient for direct AC mains or outdoor line coupling. Primary protection requires upstream MOVs or gas discharge tubes - the 1N5652/TR serves as the final-stage clamp after coarse protection stages.
