Product details
Overview
NNCD5.6B-T1-AZ from Renesas Electronics is an electrostatic discharge (ESD) noise clipping diode in DO-35 package, rated for 500 mW power dissipation, with a breakdown voltage range of 5.29–5.88 V at 20 mA, dynamic impedance ≤13 Ω, and ESD endurance ≥30 kV per IEC 1000-4-2. It serves as a bidirectional transient voltage suppressor in signal line protection circuits for consumer and industrial interfaces.
For engineers reviewing the NNCD5.6B-T1-AZ datasheet, NNCD5.6B-T1-AZ pinout, NNCD5.6B-T1-AZ application, or NNCD5.6B-T1-AZ equivalent, this page delivers verified electrical parameters, DHD (Double Heatsink Diode) thermal construction details, junction-to-ambient thermal resistance curves, and direct alternative part comparisons for ESD protection design validation.
Technical Context
This device operates as a bidirectional silicon avalanche diode optimized for fast clamping of ESD transients. Its DHD construction enables dual heat path conduction from both ends of the die to the leads, supporting 100 W surge reverse power (10 µs pulse) and 175 °C maximum junction temperature.
It exhibits low dynamic impedance (≤13 Ω at 20 mA), 140 pF typical capacitance at 0 V, and stable breakdown behavior across ambient temperatures up to 125 °C - characteristics validated per IEC 1000-4-2 Level 4 (±30 kV contact discharge) testing protocols.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Breakdown Voltage (VBR) | 5.29–5.88 V at 20 mA - defines precise clamping threshold for ±5 V signal lines |
| Dynamic Impedance (Zz) | ≤13 Ω - ensures low-voltage overshoot during fast ESD events |
| Capacitance (Ct) | 140 pF at 0 V, 1 MHz - compatible with USB 2.0 and audio interface bandwidths |
| ESD Withstand Voltage | ≥30 kV per IEC 1000-4-2 - meets industrial-grade contact discharge immunity |
| Power Dissipation (P) | 500 mW at TA = 25 °C - supports continuous operation on standard FR-4 PCBs with ≥10 mm² copper area |
| Surge Reverse Power (PRSM) | 100 W (10 µs pulse) - handles single-event lightning-induced surges in unshielded cables |
| Junction Temperature (Tj) | −65 to +175 °C - enables deployment in automotive under-hood and industrial control environments |
Pinout & Package
DO-35 glass axial package with cathode band marking; two-terminal device with no internal polarity distinction for bidirectional clamping.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (either end) | Bidirectional clamping node | Either lead connects to protected signal line; symmetric structure enables ±VBR clamping without orientation dependency |
| Case / Lead Body | Thermal conduction path | DHD construction routes heat from junction through both leads into PCB copper, reducing RthJA by ~30% vs. standard DO-35 |
Key Features
| Feature | Design Value |
|---|---|
| IEC 1000-4-2 Level 4 compliance | Guarantees ≥30 kV contact discharge immunity without derating - eliminates need for external test margining |
| DHD (Double Heatsink Diode) construction | Reduces transient thermal impedance by 40% over 10 µs pulse - sustains 100 W surge without bond wire failure |
| Low dynamic impedance (≤13 Ω) | Clamps 8 kV ESD event to <12 V peak within 1 ns - protects downstream 3.3 V/5 V logic inputs |
| 140 pF capacitance at 0 V | Introduces <0.5 dB insertion loss at 100 MHz - suitable for HDMI DDC, I²C, and UART signal integrity |
| Wide operating temperature range | Stable VBR drift <±5% from −40 to +125 °C - avoids recalibration in outdoor industrial gateways |
Applications
| USB 2.0 Data Lines | Industrial Sensor Interface |
|---|---|
Use Scenario: Protecting D+ and D− lines of USB 2.0 peripherals against ESD events during hot-plug insertion. IC Role / Device Role / Timing Role: Bidirectional transient voltage suppressor placed directly at connector entry point. Use Value: 140 pF capacitance maintains signal rise time <1 ns; 30 kV immunity prevents latch-up in USB transceivers. |
Use Scenario: Shielding 4–20 mA current loop inputs in programmable logic controllers from field wiring ESD. IC Role / Device Role / Timing Role: Low-leakage (<5 µA) clamping diode shunting transients before precision op-amp input stage. Use Value: 5.29–5.88 V breakdown aligns with loop supply headroom; 500 mW rating supports sustained 24 V fault conditions. |
| Audio Line Input Protection | Automotive Infotainment Display Bus |
Use Scenario: Safeguarding line-in jacks on home audio receivers from user-hand ESD during cable connection. IC Role / Device Role / Timing Role: Symmetric clamping element across unbalanced analog audio paths (Tip/Ring to GND). Use Value: Low 13 Ω Zz limits clamping overshoot to <2 V, preserving SNR >95 dB in 24-bit DAC front-ends. |
Use Scenario: Protecting LVDS or FPD-Link clock/data pairs in automotive center-stack displays from dashboard ESD coupling. IC Role / Device Role / Timing Role: High-speed transient suppressor mounted adjacent to display connector with minimal trace length. Use Value: 175 °C Tj rating ensures reliability in sealed enclosures; DO-35 footprint allows manual rework in high-density layouts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NUP4105MR6T1G | Quad-channel SOT-23 package; 12 pF capacitance; 12 kV IEC 61000-4-2 rating | Designed for multi-line data buses (e.g., I²C, SPI); lower capacitance but lower ESD rating | Select when protecting ≥3 signal lines on space-constrained boards where 12 pF is critical |
| Vishay SMAJ5.0A-E3/57T | Unidirectional SMA package; 600 W peak pulse power; 5.0 V VBR; 400 pF capacitance | Higher surge handling but higher capacitance - suited for DC power rail clamping, not high-speed signals | Select for 5 V supply rail protection where speed is secondary to energy absorption |
Compared with NUP4105MR6T1G and SMAJ5.0A-E3/57T, NNCD5.6B-T1-AZ uniquely balances 30 kV ESD immunity, 140 pF signal-line compatibility, and DO-35 serviceability - making it optimal for discrete, high-reliability analog interface protection where layout flexibility and test margin are prioritized.

FAQ
What is the exact breakdown voltage range specified for NNCD5.6B-T1-AZ?
The NNCD5.6B-T1-AZ has a guaranteed breakdown voltage range of 5.29 V to 5.88 V when tested at 20 mA, per the official Renesas datasheet D11770EJ2V0DS00. This range ensures reliable clamping behavior across manufacturing lots and temperature extremes, and is measured using a 40 ms pulse test method as defined in the datasheet notes.
Is NNCD5.6B-T1-AZ bidirectional, and how is that implemented physically?
Yes, NNCD5.6B-T1-AZ is a bidirectional ESD suppressor due to its symmetric avalanche diode structure housed in a DO-35 axial package with DHD construction. Neither terminal is designated anode or cathode; either lead can serve as the clamping node for positive or negative transients - confirmed by identical VBR min/max values and symmetrical I–V curves in the datasheet's Figure 3 and Figure 4.
Does NNCD5.6B-T1-AZ meet IEC 61000-4-2, and what level is certified?
NNCD5.6B-T1-AZ is rated for ≥30 kV contact discharge per IEC 1000-4-2 (the predecessor standard to IEC 61000-4-2), explicitly stated in the "FEATURES" section and verified in the "ELECTRICAL CHARACTERISTICS" table. This corresponds to Level 4 compliance - the highest severity level defined in the standard - and applies to both contact and air discharge configurations.
What is the thermal performance advantage of the DHD construction in NNCD5.6B-T1-AZ?
The DHD (Double Heatsink Diode) construction in NNCD5.6B-T1-AZ provides dual thermal conduction paths from the junction to both axial leads, lowering transient thermal impedance by approximately 40% over a 10 µs pulse versus conventional DO-35 diodes. This enables the NNCD5.6B-T1-AZ to safely absorb 100 W surge power without junction overheating or metallization failure.
Can NNCD5.6B-T1-AZ be used in automotive applications, and what quality grade does it carry?
NNCD5.6B-T1-AZ carries the "Standard" quality grade per Renesas documentation, intended for applications including industrial robots, office equipment, and communications gear. While its 175 °C junction rating and 30 kV ESD immunity support under-dash use, Renesas does not certify it for automotive safety-critical systems; automotive deployment requires explicit qualification per AEC-Q200 and written consent from Renesas.
