Product details
Overview
HZS24-3LTA-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 24.3–25.5 V at 0.5 mA test current, 400 mW power dissipation, and dynamic resistance of 120 Ω - enabling stable regulation in low-drift power supplies and sensor biasing applications.
For engineers reviewing the HZS24-3LTA-E datasheet, HZS24-3LTA-E pinout, HZS24-3LTA-E application, or HZS24-3LTA-E equivalent, this device is selected for noise-sensitive analog references where zener impedance, temperature coefficient (±0.04 %/°C typical), and leakage current (<1 μA at VR = 20 V) directly impact system accuracy and long-term stability.
Technical Context
This Zener diode employs a planar diffusion structure to minimize flicker noise and achieve ~1/3–1/10 lower noise than legacy HZ-series devices. Its low leakage (<1 μA) and tight zener voltage tolerance (±0.6 V at 25°C) support high-precision DC reference generation without external filtering.
The device operates with a junction temperature range up to 200°C and exhibits a zener voltage temperature coefficient near zero at ~24 V - confirmed by Fig.2 in REJ03G0166-0300 - making it suitable for industrial-grade voltage references requiring minimal thermal drift across −55°C to +175°C storage conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 24.3 V min / 25.5 V max at IZ = 0.5 mA - defines stable regulation point for mid-range analog supply rails. |
| Dynamic Resistance (rd) | 120 Ω max at IZ = 0.5 mA - ensures minimal output voltage variation under load transients. |
| Power Dissipation (Pd) | 400 mW - supports continuous operation in compact PCB layouts without forced cooling. |
| Reverse Leakage (IR) | <1 μA at VR = 20 V - preserves accuracy in high-impedance reference nodes and battery-powered systems. |
| Zener Voltage Tempco (γZ) | ±0.04 %/°C typical - enables <±0.1% total drift over −40°C to +85°C ambient, critical for metrology-grade references. |
| Junction Temperature (Tj) | 200°C max - allows reliable operation in thermally constrained enclosures or near heat-generating components. |
| Package | MHD (JEITA GRZZ0002ZC-A) - 2-pin axial lead, 5 mm pitch compatible with high-speed automatic insertion. |
Pinout & Package
Package: MHD - axial-leaded, glass-passivated silicon planar Zener diode with cathode band marking; dimensions per JEITA GRZZ0002ZC-A: body diameter φD = 2.0 mm (nom), length L = 26.0 mm (min), mass ≈ 0.084 g.
| Pin/Terminal | Circuit Role | Design Meaning |

Key Features
| Feature | Design Value |
|---|---|
| Low-noise Zener structure | ~1/3–1/10 noise vs. HZ series - reduces RMS voltage noise in precision references and ADC bias networks. |
| Tight VZ tolerance | ±0.6 V at 24.3–25.5 V - eliminates need for post-calibration trimming in factory-set analog modules. |
| Low zener impedance | 120 Ω max - maintains regulation accuracy under varying load currents in feedback-controlled supplies. |
| High-temperature reliability | 200°C max Tj - supports deployment in automotive engine-control or industrial motor-drive environments. |

FAQ
What is the zener voltage range of the HZS24-3LTA-E?
The HZS24-3LTA-E has a specified zener voltage range of 24.3 V minimum to 25.5 V maximum at a test current of 0.5 mA, as documented in the REJ03G0166-0300 datasheet. This tight 1.2 V span reflects its role as a precision reference rather than a general-purpose regulator. The HZS24-3LTA-E achieves this accuracy via planar diffusion process control and screening during final test.
Does the HZS24-3LTA-E support high-temperature operation?
Yes, the HZS24-3LTA-E is rated for a maximum junction temperature of 200°C and storage temperature from −55°C to +175°C. Its silicon planar construction and glass passivation enable reliable operation in industrial motor drives and under-hood automotive modules. The HZS24-3LTA-E maintains specified dynamic resistance and leakage performance within these limits when derated per Fig.3 in the datasheet.
How does the noise performance of HZS24-3LTA-E compare to standard Zener diodes?
The HZS24-3LTA-E delivers approximately 1/3 to 1/10 the noise level of legacy HZ-series Zeners due to its optimized planar structure and low-flicker-noise processing. This is critical in applications like precision ADC references and low-level sensor excitation, where HZS24-3LTA-E's reduced noise floor directly improves effective resolution. The HZS24-3LTA-E datasheet confirms this advantage in its Features section and noise characterization context.
Is the HZS24-3LTA-E RoHS compliant?
Yes, the HZS24-3LTA-E complies with the EU RoHS Directive, as confirmed by Renesas Electronics' environmental compliance documentation and material declarations. Lead-free termination and halogen-free packaging meet current regulatory requirements for industrial and commercial electronics. Customers can verify RoHS status using Renesas' official product change notices and material content reports for HZS24-3LTA-E.
What is the package type and lead pitch of the HZS24-3LTA-E?
The HZS24-3LTA-E uses the MHD package (JEITA code GRZZ0002ZC-A), an axial-leaded glass-body Zener diode with 5 mm lead pitch - optimized for high-speed automatic insertion equipment. Its dimensions are standardized: body diameter 2.0 mm (nominal), length 26.0 mm (minimum), and mass 0.084 g. The cathode is marked by a black band on the HZS24-3LTA-E body.
