Product details
Overview
JAN1N5632A from Microchip Technology is a hermetically sealed, unidirectional transient voltage suppressor (TVS) diode in DO-13 metal package, designed for high-reliability military avionics and industrial systems. It features 7.37 V rated standoff voltage (VWM), 8.19–8.65 V breakdown voltage (V(BR)) at 1 mA, 13.4 V maximum clamping voltage (VC) at 112 A peak pulse current, and 1500 W peak pulse power rating per 10/1000 µs waveform.
For engineers reviewing the JAN1N5632A datasheet, JAN1N5632A pinout, JAN1N5632A application, or JAN1N5632A equivalent, this device is selected for ESD/EFT protection per IEC 61000-4-2/-4-4, secondary lightning surge suppression per IEC 61000-4-5 (up to Class 4 with 2 Ω source impedance), and inductive switching transient clamping in harsh-environment power electronics.
Technical Context
The JAN1N5632A operates as a unidirectional avalanche diode, entering controlled breakdown when reverse voltage exceeds its V(BR) threshold to clamp transients within nanoseconds. Its hermetic DO-13 metal-glass package ensures stable performance across -55°C to +175°C operating temperature range and inherent radiation hardness per MicroNote 050.
It delivers 1500 W non-repetitive peak pulse power at TL = 25°C with <100 ps response time, and maintains low standby leakage (<50 µA at VWM) while supporting 200 A forward surge current (8.3 ms half-sine). Thermal resistance is 50°C/W junction-to-lead at 10 mm lead length.

FAQ
What is the standoff voltage (VWM) of the JAN1N5632A and how is it applied in circuit design?
The JAN1N5632A has a rated standoff voltage (VWM) of 7.37 V, meaning it remains non-conductive up to this reverse DC or continuous peak voltage. In circuit design, VWM must be ≥ the maximum normal operating voltage of the protected line-e.g., used on a 5 V logic rail with margin, or a 6.5 V sensor supply-to avoid leakage or premature conduction. This value is confirmed per JEDEC test conditions at 25°C and defines the upper limit of safe steady-state bias.
How does the JAN1N5632A differ from commercial-grade 1N5632A in terms of qualification and reliability?
The JAN1N5632A is fully qualified to MIL-PRF-19500/500 Level JANTX, including rigorous screening for thermal shock, vibration, hermeticity, and lot acceptance testing. Unlike commercial 1N5632A, it guarantees operation from -55°C to +175°C, provides certified radiation hardness per MicroNote 050, and ships with full traceability documentation-making JAN1N5632A mandatory for deployed defense and flight hardware where field failure is unacceptable.
Can the JAN1N5632A be used for bidirectional transient suppression?
No-the JAN1N5632A is a unidirectional TVS diode, optimized for clamping reverse-polarity transients only. Its cathode is internally connected to the metal case, and it conducts only when reverse-biased beyond V(BR). For bidirectional protection (e.g., AC lines or differential buses), Microchip specifies separate devices such as the 1N6036–1N6072A series in the same DO-13 package-JAN1N5632A must be paired with a second diode or replaced with a dedicated bidirectional part for symmetrical surge handling.
What is the maximum clamping voltage (VC) of the JAN1N5632A and why is it critical for system protection?
The JAN1N5632A exhibits a maximum clamping voltage (VC) of 13.4 V at 112 A peak pulse current (10/1000 µs waveform). This value represents the highest voltage imposed on the protected circuit during worst-case surge events. It is critical because downstream components-such as 12 V-rated microcontrollers or level-shifters-must tolerate this clamped voltage without damage; exceeding VC risks latch-up, gate rupture, or permanent failure in adjacent ICs.
Is the JAN1N5632A compatible with lead-free soldering processes?
No-the JAN1N5632A features tin-lead (SnPb) plating per MIL-STD-750 Method 2026 and is rated for maximum solder temperature of 260°C for 10 seconds. It is not qualified for lead-free reflow profiles (typically >260°C peak), and exposure to higher temperatures may compromise hermetic seal integrity or internal bond reliability. For RoHS-compliant designs, consult Microchip's surface-mount SMCJ/SMCG equivalents or verify alternate qualified versions explicitly marked for Pb-free assembly.
