Product details
Overview
HZS11B3LTD-E from Renesas Electronics is a silicon planar Zener diode optimized for low-noise voltage reference and stabilization in precision analog circuits, featuring a nominal zener voltage of 10.7–11.1 V, dynamic resistance of 80 Ω at 0.5 mA, and maximum power dissipation of 400 mW. It delivers approximately 1/3–1/10 lower noise than the legacy HZ series and is rated for junction temperatures up to 200°C.
For engineers reviewing the HZS11B3LTD-E datasheet, HZS11B3LTD-E pinout, HZS11B3LTD-E application, or HZS11B3LTD-E equivalent, key selection criteria include its low-noise performance, tight zener voltage tolerance (±0.2 V), low leakage current (<1 μA at VR = 2.0 V), suitability for 5 mm-pitch automated insertion, and compliance with industrial-grade reliability standards.
Technical Context
This device operates as a two-terminal, DC-biased voltage reference using silicon planar Zener breakdown. Its low dynamic impedance (80 Ω) ensures stable regulation under varying load currents, while its low noise spectral density supports high-fidelity signal conditioning in sensor front-ends and ADC reference stages.
The HZS11B3LTD-E is characterized at 25°C with DC test conditions and exhibits a negative temperature coefficient (−0.04 to −0.06 mV/°C typical across the HZS-L family), requiring thermal compensation in wide-temperature-range applications. It is packaged in the MHD (JEITA GRZZ0002ZC-A) leaded through-hole package with cathode band marking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10.7–11.1 V at IZ = 0.5 mA - defines stable regulation point for low-drift references |
| Dynamic Resistance (rd) | 80 Ω max at IZ = 0.5 mA - ensures minimal output voltage variation under load transients |
| Reverse Current (IR) | <1 μA at VR = 2.0 V - enables ultra-low quiescent current biasing in battery-powered designs |
| Power Dissipation (Pd) | 400 mW max - supports continuous operation in compact PCB layouts without forced cooling |
| Junction Temperature (Tj) | −55 to +200°C - allows deployment in high-temperature industrial environments (e.g., motor control, power supplies) |
| Noise Level | ≈1/3–1/10 of HZ-series diodes - critical for audio preamps, precision instrumentation amplifiers, and metrology systems |
Pinout & Package
Package: MHD (JEITA GRZZ0002ZC-A), axial-leaded, 5 mm pitch, 2.0 mm diameter body, 26 mm length, 0.084 g typical mass. Cathode identified by black band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener breakdown terminal | Connected to regulated output node; reverse-biased during normal operation |
| 2 (Anode) | Reference ground return | Provides current return path; must be tied to system ground or bias rail |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise Zener operation | 1/3–1/10 noise vs. HZ series - directly improves SNR in voltage-referenced measurement circuits |
| Stable low-impedance regulation | 80 Ω dynamic resistance at 0.5 mA - maintains <±10 mV output shift across ±5 mA load changes |
| High-temperature capability | 200°C max junction temperature - enables use in engine-control modules and industrial power converters |
| Automated assembly compatibility | 5 mm pitch, axial MHD package - supports high-throughput placement on legacy and modern SMT-compatible through-hole lines |
| Wide zener voltage range support | Part of 5.2–38 V HZS-L family - allows design reuse across multiple supply rails without topology change |
Applications
| Industrial Power Supply Reference | Precision Sensor Signal Conditioning |
|---|---|
|
Use Scenario: Stabilizing feedback voltage in isolated DC-DC converter secondary-side regulation. IC Role / Device Role / Timing Role: Two-terminal shunt voltage reference providing accurate 11 V setpoint for optocoupler-driven error amplifier. Use Value: Low dynamic resistance (80 Ω) minimizes regulation error under line/load transients; low noise prevents coupling into control loop. |

IC Role / Device Role / Timing Role: Low-drift, low-noise excitation reference replacing higher-cost IC references. Use Value: 10.7–11.1 V range matches common bridge excitation needs; sub-μA leakage avoids sensor offset errors. |

|
Use Scenario: Providing clean bias voltage for JFET-input op-amps in microphone preamplifiers. IC Role / Device Role / Timing Role: Low-noise Zener source replacing noisy resistor-divider networks. Use Value: Noise reduction by factor of 3–10 directly lowers input-referred noise floor below 100 Hz. |
Use Scenario: Serving as traceable voltage standard in portable multimeter calibration circuits. IC Role / Device Role / Timing Role: Stable, low-drift shunt reference used in self-test and auto-zero functions. Use Value: Tight 0.2 V tolerance and −0.05 mV/°C tempco enable ±0.5% accuracy over 0–70°C without trimming. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor 1N4740A | Zener voltage 10 V ±5%, rd = 17 Ω, Pd = 1 W, DO-41 package | Higher power rating but wider voltage tolerance and higher noise than HZS11B3LTD-E | Preferred where higher power margin is needed; not suitable for ultra-low-noise or tight-tolerance designs |
| Vishay BZX55C10 | Zener voltage 10 V ±5%, rd = 20 Ω, Pd = 500 mW, DO-35 package | Lower noise than 1N4740A but still 3× higher than HZS11B3LTD-E; no documented low-noise optimization | Acceptable for general-purpose regulation; lacks HZS-L's verified low-noise specification and industrial temp range |
Compared with 1N4740A and BZX55C10, the HZS11B3LTD-E provides tighter voltage tolerance (±0.2 V vs. ±5%), significantly lower noise, and guaranteed 200°C junction rating-making it uniquely suited for high-reliability, low-noise industrial and test equipment where reference stability is critical.

FAQ
What is the exact zener voltage range specified for HZS11B3LTD-E?
The HZS11B3LTD-E has a guaranteed zener voltage range of 10.7 V to 11.1 V when tested at IZ = 0.5 mA and Ta = 25°C. This ±0.2 V tolerance is significantly tighter than standard Zener diodes (typically ±5%), enabling high-accuracy regulation without external trimming. The value is measured under DC conditions per Renesas REJ03G0166-0300 Rev.3.00.
Does HZS11B3LTD-E support automated PCB assembly?
Yes, the HZS11B3LTD-E uses the MHD package (JEITA GRZZ0002ZC-A) with 5 mm lead pitch and axial lead configuration, explicitly qualified for high-speed automatic insertion. Its mechanical dimensions-including 2.0 mm body diameter and 26 mm length-are optimized for compatibility with standard axial component feeders and placement heads.
How does the noise performance of HZS11B3LTD-E compare to standard Zener diodes?
The HZS11B3LTD-E achieves approximately 1/3 to 1/10 the noise level of the legacy HZ series, as confirmed in Renesas documentation. This low-noise characteristic stems from optimized silicon planar process and controlled Zener breakdown physics-not post-manufacturing screening-making it suitable for audio preamps, precision ADC references, and low-level sensor signal chains where noise floor matters.
What is the maximum allowable junction temperature for HZS11B3LTD-E?
The absolute maximum junction temperature for HZS11B3LTD-E is +200°C, as specified in the Absolute Maximum Ratings table of the Renesas datasheet REJ03G0166-0300. This exceeds typical commercial-grade Zeners (150°C) and supports reliable operation in high-temperature environments such as motor drives, industrial power converters, and under-hood automotive subsystems.
Is HZS11B3LTD-E RoHS compliant and lead-free?
Yes, HZS11B3LTD-E meets EU RoHS Directive requirements. Renesas confirms environmental compliance for the HZS-L series in accordance with applicable laws and regulations governing controlled substances. Full material declarations and compliance certificates are available upon request from Aetrix Electronics for production traceability.
