Product details
Overview
1N5630A/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 6.40 V rated standoff voltage (VWM), 7.14–7.88 V breakdown voltage (V(BR)) at 10 mA, 11.3 V maximum clamping voltage (VC) at 132 A peak pulse current, and 1500 W peak pulse power rating per 10/1000 µs waveform.
For engineers reviewing the 1N5630A/TR datasheet, 1N5630A/TR pinout, 1N5630A/TR application, or 1N5630A/TR equivalent, this device is selected for ESD/EFT protection per IEC 61000-4-2/4-4, secondary lightning protection per IEC 61000-4-5 (with 2–42 Ω source impedance), and fast-response (<100 ps) clamping in inductive switching environments where radiation hardness and hermetic reliability are critical.
Technical Context
The 1N5630A/TR operates as a unidirectional avalanche diode, entering controlled breakdown above its VWM to clamp transients while maintaining low leakage (<500 µA at 6.40 V). Its DO-13 metal-glass package ensures hermetic sealing and inherent radiation hardness per MicroNote 050, supporting operation from –55°C to +175°C.
It delivers 1500 W peak pulse power with <100 ps response time and thermal resistance of 50°C/W junction-to-lead, enabling robust protection against fast-rising surges without PCB layout compromises. The cathode is internally connected to the case, requiring proper grounding in circuit design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Rated Standoff Voltage) | 6.40 V - Maximum continuous reverse voltage before conduction; sets minimum system operating margin. |
| V(BR) @ I(BR) | 7.14–7.88 V at 10 mA - Confirmed avalanche onset range; defines precise trigger threshold under test conditions. |
| VC @ IPP | 11.3 V at 132 A - Maximum clamped voltage during 10/1000 µs surge; determines worst-case voltage seen by protected ICs. |
| PPP | 1500 W - Peak pulse power handling capability; enables protection against high-energy transients like lightning-induced surges. |
| ID @ VWM | 500 µA - Reverse leakage at rated standoff; low enough to avoid loading sensitive signal lines or power rails. |
| Response Time | <100 ps - Near-instantaneous clamping onset; prevents sub-nanosecond ESD events from damaging downstream components. |
| Package | DO-13 (DO-202AA) - Hermetically sealed metal-glass through-hole package; provides MIL-qualified mechanical robustness and radiation tolerance. |
Pinout & Package
Package: DO-13 (DO-202AA), hermetically sealed metal-glass case with tin-lead plated leads. Cathode terminal is electrically connected to the case and marked with a diode symbol on the body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 2) | Transient current entry point | Connected to protected line; carries full surge current into the diode junction during clamping. |
| Cathode (Lead 1 / Case) | Clamping reference and return path | Internally tied to metal case; must be solidly grounded to shunt surge energy safely to earth/chassis. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional TVS architecture | Enables precise overvoltage clamping on DC-biased lines without forward-conduction interference. |
| 1500 W peak pulse power (10/1000 µs) | Supports Class 4 secondary lightning protection per IEC 61000-4-5 with 42 Ω source impedance. |
| Hermetic DO-13 metal package | Ensures long-term reliability in high-humidity, high-vibration, and radiation-exposed environments (e.g., avionics). |
| <100 ps response time | Protects against nanosecond-scale ESD events (IEC 61000-4-2) before sensitive CMOS inputs fail. |
| MIL-PRF-19500/500 qualified "A" suffix | Guarantees tighter parametric tolerances and screening for military/aerospace applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5630A | No tape-and-reel packaging; leaded bulk format only. | Lacks TR suffix; unsuitable for automated SMT assembly but preferred for manual prototyping or low-volume repair. | Select 1N5630A when reel feed is unnecessary and cost-per-unit optimization is prioritized over placement efficiency. |
| SMBJ6.0A | Surface-mount SMB package; 6.0 V VWM; 10.3 V VC @ 103 A; lower 600 W PPP rating. | Designed for space-constrained PCBs; lacks hermetic seal and radiation hardness; not qualified to MIL-PRF-19500. | Choose SMBJ6.0A only for commercial-grade, non-safety-critical applications where DO-13 footprint and military qualification are not required. |
Compared with 1N5630A/TR, the 1N5630A offers identical electrical specs but no tape-and-reel convenience, while SMBJ6.0A trades hermetic reliability, radiation tolerance, and 1500 W surge capacity for surface-mount compatibility-making 1N5630A/TR the sole choice for mission-critical avionics and high-surge industrial deployments.

FAQ
What is the maximum clamping voltage of the 1N5630A/TR under a 10/1000 µs surge?
The 1N5630A/TR exhibits a maximum clamping voltage (VC) of 11.3 V when subjected to its rated peak pulse current of 132 A under the standard 10/1000 µs waveform. This value is measured at 25°C and defines the upper voltage limit imposed on protected circuits during transient events, ensuring downstream ICs remain within safe operating margins.
Is the 1N5630A/TR suitable for ESD protection per IEC 61000-4-2?
Yes, the 1N5630A/TR is explicitly validated for ESD protection per IEC 61000-4-2 due to its sub-100 ps response time and low clamping voltage. Its ability to clamp nanosecond-scale discharges without degradation makes it appropriate for protecting sensitive inputs in avionics and medical equipment where human-body-model (HBM) and contact-discharge events occur.
Does the 1N5630A/TR have military qualification?
Yes, the "A" suffix in 1N5630A/TR denotes compliance with MIL-PRF-19500/500 for tighter parametric tolerances and screening. When ordered with JAN, JANTX, or JANTXV prefixes (e.g., JANTXV1N5630A), it receives full military qualification including environmental stress screening and lot traceability-critical for defense and space applications.
What is the thermal resistance of the 1N5630A/TR, and how does it affect layout?
The 1N5630A/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 value allows efficient heat dissipation during repetitive surges but requires adequate copper pour and grounding of the cathode (case) to minimize localized heating and ensure long-term reliability in high-duty-cycle environments.
How does the DO-13 package of the 1N5630A/TR differ from plastic axial-leaded TVS diodes?
The DO-13 package of the 1N5630A/TR is a welded, hermetically sealed metal-glass construction-unlike plastic axial-leaded equivalents-which provides superior moisture resistance, mechanical ruggedness, and inherent radiation hardness. This makes the 1N5630A/TR suitable for aerospace, downhole, and nuclear instrumentation where long-term parameter stability under harsh conditions is mandatory.
