Product details
Overview
RD110E-TB-AZ from NEC Corporation is a silicon planar epitaxial Zener diode in SC-76 (SSP) package, rated for 11 V nominal Zener voltage at 5 mA test current, with 5% tolerance and 500 mW power dissipation. It serves as a precision voltage reference or overvoltage clamp in low-power analog signal conditioning circuits.
For engineers reviewing the RD110E-TB-AZ datasheet, RD110E-TB-AZ pinout, RD110E-TB-AZ application, or RD110E-TB-AZ equivalent, key selection criteria include Zener voltage accuracy, temperature coefficient, dynamic impedance, maximum reverse leakage, and SC-76 mechanical compatibility with automated pick-and-place systems.
Technical Context
This device operates in reverse breakdown mode with a specified Zener voltage of 11.0 V ±5% at IZ = 5 mA. Its typical dynamic impedance is 20 Ω at IZ = 5 mA, and temperature coefficient is +0.08 %/°C over the -55°C to +150°C operating range.
The RD110E-TB-AZ exhibits maximum reverse leakage current of 1 μA at 8.8 V and maximum forward voltage of 1.2 V at IF = 10 mA, confirming its suitability for bidirectional clamping and reference applications requiring stable low-current regulation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C11LT1G | 11 V ±5%, SOT-23 package, 350 mW PD, 30 Ω ZZT | Higher thermal resistance limits sustained 5 mA operation in high ambient temperatures | Preferred where board space permits SOT-23 and power demand stays below 350 mW |
| MMSZ4688T1G | 11 V ±5%, SOD-123 package, 500 mW PD, 30 Ω ZZT | Larger 2.9 mm × 1.7 mm footprint requires layout revision vs. SC-76's 1.3 mm × 0.8 mm | Chosen when higher surge robustness is needed and SC-76 footprint is not constrained |

FAQ
What is the Zener voltage tolerance of RD110E-TB-AZ?
The RD110E-TB-AZ has a Zener voltage tolerance of ±5% at 5 mA test current, meaning its actual breakdown voltage falls between 10.45 V and 11.55 V under standard test conditions. This tolerance is verified per NEC's original specification sheet and applies across the full operating temperature range from –55°C to +150°C. The RD110E-TB-AZ maintains this accuracy without external trimming or calibration.
Does RD110E-TB-AZ support automotive-grade temperature operation?
Yes, RD110E-TB-AZ is rated for operation from –55°C to +150°C, meeting extended temperature requirements for under-hood automotive applications such as engine control modules and transmission sensors. Its silicon planar epitaxial construction and SC-76 package ensure mechanical and thermal stability across this range. The RD110E-TB-AZ retains specified Zener voltage accuracy and leakage performance throughout this envelope.
What is the maximum reverse leakage current for RD110E-TB-AZ?
The RD110E-TB-AZ specifies a maximum reverse leakage current of 1 μA at 8.8 V (80% of nominal Zener voltage), measured at 25°C. This low leakage enables use in high-impedance bias networks and battery-sensitive applications. The RD110E-TB-AZ maintains leakage below 5 μA even at +150°C, supporting reliable operation in thermally aggressive environments.
Is RD110E-TB-AZ compatible with standard SC-76 pick-and-place equipment?
Yes, RD110E-TB-AZ uses the standardized SC-76 (SSP) package with 1.3 mm × 0.8 mm footprint and 0.55 mm height, fully compatible with industry-standard 0805-sized nozzles and vision-guided placement systems. The -TB-AZ suffix confirms compliance with NEC's SC-76 taping specification, including reel dimensions and orientation. RD110E-TB-AZ feeds reliably through automated assembly lines without adapter tooling.
How does RD110E-TB-AZ compare to general-purpose 11 V Zeners in dynamic impedance?
RD110E-TB-AZ achieves a maximum dynamic impedance of 20 Ω at 5 mA, significantly lower than typical 11 V Zeners (often 30–50 Ω). This results in tighter voltage regulation under varying load conditions. The RD110E-TB-AZ's low ZZT is achieved through optimized epitaxial layer doping and junction geometry, directly improving noise rejection and transient response in precision reference circuits.
