Product details
Overview
1N5636A/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 11.1 V rated standoff voltage (VWM), 12.4 V minimum breakdown voltage (V(BR)), 18.2 V maximum clamping voltage (VC) at 82 A peak pulse current, and 1500 W peak pulse power rating per 10/1000 µs waveform.
For engineers reviewing the 1N5636A/TR datasheet, 1N5636A/TR pinout, 1N5636A/TR application, or 1N5636A/TR equivalent, this device is selected for secondary lightning protection (IEC61000-4-5, 4 Ω source), ESD/EFT immunity (IEC61000-4-2/-4), and inductive switching transient suppression in avionics power rails and military-grade DC distribution networks.
Technical Context
The 1N5636A/TR operates as a unidirectional avalanche-clamping TVS diode with cathode connected to case, enabling low-inductance mounting directly to chassis ground. Its response time is under 100 ps, ensuring sub-nanosecond clamping during fast transients such as ESD events or RF-induced surges.
Rated for -55°C to +175°C operation and hermetically sealed in DO-13 (DO-202AA), it maintains stable V(BR) temperature coefficient of 0.081 %/°C and withstands 200 A forward surge current (8.3 ms half-sine). Thermal resistance is 50°C/W junction-to-lead at 10 mm lead length.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 11.1 V - Maximum continuous reverse operating voltage before avalanche conduction begins; sets system-level DC rail compatibility. |
| V(BR) min | 12.4 V @ 1 mA - Minimum breakdown threshold guaranteeing reliable turn-on above normal operating voltage. |
| VC @ IPP | 18.2 V @ 82 A - Peak clamped voltage during 10/1000 µs surge; defines worst-case overvoltage seen by protected circuitry. |
| PPP | 1500 W - Non-repetitive peak pulse power handling capability; determines survivability against IEC61000-4-5 Class 4 surges. |
| ID @ VWM | 5 µA - Standby leakage current at rated standoff voltage; ensures minimal power loss in always-on systems. |

Pinout & Package
DO-13 (DO-202AA) hermetically sealed metal-glass axial package with cathode terminal electrically connected to case. Polarity marked by diode symbol on body; cathode lead is designated Lead 1 per Microsemi package drawing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 2) | Transient current entry point | Connected to protected line; carries full surge current into avalanche region during clamping. |
| Cathode (Lead 1) | Ground reference / case connection | Internally bonded to metal case; must be soldered to low-impedance ground plane or chassis for optimal ESD/lightning performance. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5636A (bulk) | No tape-and-reel packaging; same electrical specs and DO-13 package. | Suitable for manual assembly or low-volume prototyping where reel feeding is unnecessary. | Select 1N5636A/TR when automated SMT placement or high-volume production requires EIA-296 compliant tape-and-reel delivery. |
| SMCJ12A | Surface-mount SMC package; 12 V VWM, 19.9 V VC @ 75.4 A; lower thermal resistance (junction-to-ambient). | Better suited for space-constrained PCBs but lacks hermetic sealing and radiation hardness of DO-13. | Choose SMCJ12A only if board area is critical and military environmental compliance is not required. |
Compared with 1N5636A/TR, the bulk 1N5636A offers identical protection performance without reel logistics, while SMCJ12A trades hermetic reliability and temperature range for surface-mount convenience-making 1N5636A/TR the sole choice for radiation-hardened, high-temperature, or chassis-grounded avionics designs.

FAQ
What is the clamping voltage of the 1N5636A/TR under standard 10/1000 µs surge conditions?
The 1N5636A/TR has a maximum clamping voltage (VC) of 18.2 V when subjected to its rated 82 A peak pulse current under the 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and reflects worst-case voltage seen by protected circuitry during surge events, making it suitable for safeguarding 12–15 V systems with margin.
Is the 1N5636A/TR suitable for IEC61000-4-5 secondary lightning protection?
Yes, the 1N5636A/TR is explicitly rated for IEC61000-4-5 secondary lightning protection with 4 Ω source impedance (Class 4), as confirmed in the Applications/Benefits section of the T4-LDS-0096 datasheet. Its 1500 W peak pulse power and 18.2 V clamping ensure compliance without external series impedance.
Does the 1N5636A/TR have military qualification options?
Yes, the "A" suffix in 1N5636A/TR denotes tighter parameter tolerances and supports JAN, JANTX, or JANTXV military prefixes per MIL-PRF-19500/500 when ordered with appropriate prefixing. The TR suffix indicates EIA-296 tape-and-reel packaging, fully compatible with qualified military variants.
How does the DO-13 package of the 1N5636A/TR improve surge performance compared to plastic alternatives?
The DO-13 package of the 1N5636A/TR is hermetically sealed metal-glass, providing superior thermal dissipation (50°C/W junction-to-lead), inherent radiation hardness (per MicroNote 050), and direct cathode-to-chassis grounding-critical for minimizing inductance in high-energy surge paths where plastic axial packages exhibit higher clamping overshoot and long-term moisture-related degradation.
What is the standoff voltage rating and why is it important for selecting the 1N5636A/TR?
The 1N5636A/TR has a rated standoff voltage (VWM) of 11.1 V, meaning it remains nonconductive below this DC or continuous peak voltage. This value must exceed the maximum normal operating voltage of the protected line-e.g., for a 9 V nominal rail with ±10% tolerance, 11.1 V VWM provides necessary margin while avoiding false triggering during transients.
