Product details
Overview
JANTX1N5660A from Microchip (formerly Microsemi) is a hermetically sealed, unidirectional transient voltage suppressor (TVS) diode in a DO-13 metal package, designed for high-reliability military and aerospace applications. It features a 108 V rated standoff voltage (VWM), 117 V minimum breakdown voltage (V(BR)), clamps transients to ≤187 V at 179 A peak pulse current (IPP), and delivers 1500 W peak pulse power (10/1000 µs). It is commonly deployed in avionics power bus protection against secondary lightning surges per IEC61000-4-5 with 42 Ω source impedance (Class 1).
For engineers reviewing the JANTX1N5660A datasheet, JANTX1N5660A pinout, JANTX1N5660A application, or JANTX1N5660A equivalent, key selection criteria include its MIL-PRF-19500/500 qualified JANTX-level screening, hermetic DO-13 package, sub-100 ps response time, radiation-hardened construction per MicroNote 050, and precise 108–132 V V(BR) range under 1 mA test current.
Technical Context
The JANTX1N5660A operates as an avalanche-mode unidirectional TVS diode, triggered when reverse voltage exceeds its specified V(BR) threshold (117–124 V @ 1 mA), entering low-impedance clamping mode to limit transient energy. Its hermetic DO-13 package ensures stable thermal resistance (50 °C/W junction-to-lead) and operation across –55 °C to +175 °C.
It is rated for 1500 W non-repetitive peak pulse power (10/1000 µs waveform), with clamping voltage VC = 187 V at IPP = 179 A, and exhibits a temperature coefficient of V(BR) of +0.107 %/°C - critical for high-temperature avionics environments where voltage drift must remain predictable.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 108 V - maximum continuous reverse operating voltage before conduction begins; sets system-level surge immunity margin. |
| V(BR) min/max | 117 V / 124 V @ 1 mA - defines precise avalanche initiation window; critical for deterministic clamping onset in safety-critical systems. |
| VC @ IPP | 187 V @ 179 A - peak voltage seen by protected circuit during worst-case 10/1000 µs surge; determines downstream component voltage rating requirements. |
| PPP | 1500 W - peak transient energy absorption capability; enables protection against IEC61000-4-5 Class 1 secondary lightning (42 Ω source). |
| Response time | <100 ps - ensures clamping activation prior to damage in ESD (IEC61000-4-2) and EFT (IEC61000-4-4) events. |
| Package | DO-13 (DO-202AA) - hermetically sealed metal-glass case with cathode-connected case; provides radiation hardness and long-term reliability in harsh environments. |
| Operating temp | –55 °C to +175 °C - supports deployment in engine-mounted avionics, missile guidance, and space-qualified subsystems. |
Pinout & Package
DO-13 (DO-202AA) hermetically sealed metal-glass package with axial leads; cathode terminal electrically connected to the metal case. Polarity indicated by molded diode symbol on body. Lead finish: tin-lead per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N5660A | Higher screening level (JANTXV per MIL-PRF-19500/500): includes additional tests for radiation hardness and extended temperature life testing. | Required for spaceflight and nuclear-hardened systems where TID >100 krad(Si) and mission lifetime exceeds 15 years. | Select JANTXV1N5660A when radiation tolerance beyond MicroNote 050 baseline or extended reliability validation is mandated. |
| 1N5660A (commercial grade) | No military screening; not hermetically sealed; plastic DO-15 package; V(BR) tolerance ±10% vs. ±5% for JANTX. | Suitable only for non-safety-critical industrial controls or ground-based test equipment with benign environmental profiles. | Choose 1N5660A only for cost-sensitive, non-military designs where hermeticity, radiation hardness, and guaranteed V(BR) tightness are unnecessary. |
Compared with JANTX1N5660A, JANTXV1N5660A adds verified radiation performance and extended life screening for mission-critical platforms, while 1N5660A sacrifices hermeticity, screening, and precision for lower cost in commercial applications - making JANTX1N5660A the optimal balance of military reliability and production scalability.

FAQ
What is the maximum clamping voltage of the JANTX1N5660A under standard test conditions?
The JANTX1N5660A has a maximum clamping voltage (VC) of 187 V when subjected to its rated peak pulse current (IPP) of 179 A using the 10/1000 µs waveform. This value is measured at TA = 25 °C and defines the upper voltage limit imposed on protected circuitry during surge events - a critical parameter for ensuring downstream components remain within their absolute maximum ratings.
Is the JANTX1N5660A suitable for bidirectional transient suppression?
No, the JANTX1N5660A is a unidirectional TVS diode intended for suppression of positive-going transients only. Its cathode is internally connected to the metal case, and it conducts only when reverse-biased beyond V(BR). For bidirectional protection in the same DO-13 package, Microchip specifies the separate 1N6036–1N6072A series - JANTX1N5660A must not be substituted in bidirectional applications without circuit redesign.
Does the JANTX1N5660A meet IEC61000-4-5 secondary lightning protection requirements?
Yes, the JANTX1N5660A is validated for IEC61000-4-5 secondary lightning protection up to Class 1 with 42 Ω source impedance, as confirmed in the official datasheet. Its 1500 W peak pulse power rating and 187 V clamping voltage enable compliance when properly mounted with low-inductance grounding - particularly in aircraft electrical systems where induced surges originate from nearby lightning strikes.
What is the temperature coefficient of breakdown voltage for the JANTX1N5660A?
The JANTX1N5660A has a maximum temperature coefficient of breakdown voltage (αV(BR)) of +0.107 %/°C, meaning its V(BR) increases predictably with rising junction temperature. This positive coefficient is typical of avalanche diodes and allows designers to calculate worst-case clamping margins across the full –55 °C to +175 °C operating range - essential for high-temperature engine bay installations.
How does the hermetic DO-13 package of the JANTX1N5660A improve long-term reliability?
The hermetic DO-13 metal-glass package of the JANTX1N5660A prevents moisture ingress, oxidation, and parameter drift over decades of service - a requirement for military logistics and airborne platforms with 20+ year field life. Unlike plastic-packaged alternatives, it maintains stable V(BR), low leakage, and consistent clamping performance even after thermal cycling and humidity exposure, directly supporting MIL-PRF-19500/500 qualification.
