Product details
Overview
1N5662A/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 130 V rated standoff voltage (VWM), 144 V minimum breakdown voltage (V(BR)), 219 V maximum clamping voltage (VC) at 6.8 A peak pulse current (IPP), and 1500 W peak pulse power rating per 10/1000 µs waveform.
For engineers reviewing the 1N5662A/TR datasheet, 1N5662A/TR pinout, 1N5662A/TR application, or 1N5662A/TR equivalent, this device is selected for secondary lightning protection (IEC61000-4-5 Class 4 with 42 Ω source), ESD/EFT hardening (IEC61000-4-2/-4), and inductive switching transient suppression in avionics power rails and sensor interfaces where sub-100 ps response and radiation hardness are critical.
Technical Context
The 1N5662A/TR operates as a unidirectional avalanche diode, entering controlled breakdown above its 130 V standoff voltage to clamp transients while maintaining low leakage (<5 µA at VWM). Its DO-13 package provides hermetic sealing and thermal resistance of 50 °C/W junction-to-lead, enabling operation from –55 °C to +175 °C.
It delivers 1500 W peak pulse power handling with <100 ps response time, supporting IEC61000-4-5 compliance up to Class 4 (42 Ω source) and inherently meets radiation hardness requirements per Microsemi MicroNote 050 - critical for airborne and space-grade electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - maximum continuous reverse operating voltage before conduction begins; sets system rail compatibility limit |
| V(BR) min | 144 V @ 1 mA - guaranteed avalanche initiation threshold under standardized test conditions |
| VC max | 219 V @ 6.8 A - peak clamped voltage during 10/1000 µs surge; defines worst-case overvoltage seen by protected circuit |
| PPP | 1500 W - non-repetitive surge energy absorption capability per JEDEC standard waveform |
| ID @ VWM | <5 µA - ultra-low standby leakage ensures minimal power loss in always-on systems |
| Response time | <100 ps - enables effective suppression of ESD (IEC61000-4-2) and fast EFT bursts (IEC61000-4-4) |
| Operating temp | –55 °C to +175 °C - supports deployment in extreme environments including engine bays and avionics bays |
Pinout & Package
Package: DO-13 (DO-202AA), hermetically sealed metal-glass case with cathode connected to case and polarity marked by diode symbol. Tin-lead plated leads compliant with MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry point during reverse-biased clamping | Connected internally to lead 2; must be routed to protected line (e.g., power rail or signal trace) |
| Cathode | Transient current return path and case connection | Electrically tied to metal case per Note 6; requires direct connection to ground plane or chassis for low-inductance discharge |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional TVS architecture | Enables precise clamping on positive-going transients only, avoiding interference with DC bias or bidirectional signaling |
| Hermetic DO-13 metal package | Provides long-term reliability in humid, corrosive, or high-vacuum environments where plastic packages degrade |
| Inherent radiation hardness | Validated per Microsemi MicroNote 050 - eliminates need for additional radiation qualification testing in aerospace programs |
| 1500 W peak pulse power | Supports robust protection against IEC61000-4-5 Class 4 surges (42 Ω source) without derating at 25 °C |
| Tape-and-reel packaging (TR suffix) | Enables automated through-hole assembly with EIA-296 standard carrier tape, reducing manual handling and placement errors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5662A | No TR suffix - bulk packaged, not tape-and-reel; identical electrical specs and DO-13 package | Suitable for manual or semi-automated assembly; lacks EIA-296 tape format for pick-and-place | Select 1N5662A/TR when automated through-hole insertion is required; choose 1N5662A for prototyping or low-volume hand-soldered builds |
| SMCJ130A | Surface-mount SMC package; same 130 V VWM but higher VC (219 V → 224 V); 1500 W rating retained | Requires PCB redesign for SMD footprint; better thermal performance on FR4 with copper pour but no hermetic seal | Choose SMCJ130A only if board space constraints mandate SMD or if thermal management via PCB copper outweighs hermeticity needs |
Compared with 1N5662A/TR, the 1N5662A offers identical protection performance but lacks tape-and-reel support for automated assembly, while SMCJ130A trades hermetic reliability and through-hole compatibility for surface-mount flexibility - making 1N5662A/TR optimal for high-reliability through-hole deployments in aerospace and defense.

FAQ
What is the standoff voltage (VWM) specification for the 1N5662A/TR?
The 1N5662A/TR has a rated standoff voltage (VWM) of 130 V, meaning it remains non-conductive under continuous reverse bias up to this level. This value is selected to match nominal 28 V or 115 V AC-derived DC systems with safety margin, ensuring reliable operation without leakage-induced power loss or false triggering during normal conditions.
Does the 1N5662A/TR meet IEC61000-4-5 Class 4 surge immunity requirements?
Yes, the 1N5662A/TR is validated for IEC61000-4-5 Class 4 secondary lightning protection with a 42 Ω source impedance, as confirmed in the official datasheet (T4-LDS-0096 Rev. 3, Page 2). Its 1500 W peak pulse power and 219 V clamping voltage at 6.8 A ensure compliance without external series impedance or derating at 25 °C ambient.
Is the 1N5662A/TR hermetically sealed, and why does that matter?
Yes, the 1N5662A/TR uses a DO-13 (DO-202AA) hermetically sealed metal-glass package. This construction prevents moisture ingress and corrosion in high-humidity, salt-fog, or vacuum environments - essential for avionics, satellite subsystems, and under-hood automotive electronics where plastic-packaged TVS devices may fail prematurely.
What is the thermal resistance specification for the 1N5662A/TR, and how does it affect layout?
The 1N5662A/TR has a junction-to-lead thermal resistance of 50 °C/W when measured at 0.375 inches (10 mm) from the case body. For PCB layout, this means minimizing lead length and using wide copper traces or thermal pads helps maintain safe junction temperatures during repetitive surge events - especially important in high-temperature environments like engine control units.
How does the "TR" suffix in 1N5662A/TR impact manufacturing use?
The "TR" suffix indicates tape-and-reel packaging per EIA-296 standard, enabling automated through-hole insertion equipment to feed and place the 1N5662A/TR without manual handling. This reduces labor cost, improves placement accuracy, and maintains contamination control - critical for high-mix, high-reliability production of aerospace and defense electronics where the 1N5662A/TR is commonly deployed.
