Product details
Overview
HZS15-2LTD-E from Renesas Electronics is a silicon planar Zener diode engineered for low-noise voltage regulation in precision analog and stabilized power supply circuits, with a nominal zener voltage of 14.5 V to 15.1 V, dynamic resistance of 13.0 Ω at 0.5 mA test current, and maximum power dissipation of 400 mW. It features low leakage, low zener impedance, and is optimized for high-speed automatic insertion on 5 mm-pitch PCBs.
For engineers reviewing the HZS15-2LTD-E datasheet, HZS15-2LTD-E pinout, HZS15-2LTD-E application, or HZS15-2LTD-E equivalent, key selection criteria include zener voltage tolerance (±0.3 V), temperature coefficient behavior near 15 V, noise performance relative to legacy HZ series, and compatibility with MHD package handling and thermal derating curves up to 200°C junction temperature.
Technical Context
This device operates as a two-terminal shunt voltage regulator, maintaining stable reference voltage under varying load and line conditions via controlled reverse-bias breakdown. Its planar construction ensures consistent parametric distribution and low noise-approximately 1/3 to 1/10 that of the older HZ series-making it suitable for instrumentation-grade references and low-drift bias networks.
The HZS15-2LTD-E exhibits a negative temperature coefficient near 15 V (≈ −0.04 mV/°C per Fig.2), requiring careful thermal design in high-stability applications. Absolute maximum ratings specify 400 mW power dissipation at 25°C ambient, derating linearly to zero at 175°C storage temperature and 200°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 14.5 V to 15.1 V at IZ = 0.5 mA - defines tight regulation window for mid-range reference designs. |
| Dynamic Resistance (rd) | 13.0 Ω max at IZ = 0.5 mA - determines output impedance and load regulation sensitivity. |
| Power Dissipation (Pd) | 400 mW max at Ta = 25°C - sets thermal budget for PCB layout and heatsinking requirements. |
| Junction Temperature (Tj) | 200°C max - enables operation in high-ambient industrial environments with appropriate derating. |
| Reverse Leakage (IR) | 1 μA max at VR = 12.0 V - ensures minimal quiescent current in standby or battery-powered circuits. |
| Noise Level | ≈1/3–1/10 of HZ series - directly improves signal-to-noise ratio in precision ADC reference or op-amp biasing. |
Pinout & Package
Package: MHD (JEITA code GRZZ0002ZC-A), axial leaded, 2.0 mm diameter body, 26.0 mm overall length, 0.4 mm lead diameter, 5 mm pitch compatible - designed for high-speed automated insertion and wave soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | High-side reference node | Connected to regulated output or positive rail; polarity critical for proper breakdown operation. |
| 2 (Anode) | Ground or return path | Provides current return path; must be low-impedance to maintain regulation accuracy and noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise Zener structure | 1/3–1/10 noise vs. HZ series - enables use in audio preamps, sensor excitation, and metrology references. |
| Stable zener impedance | 13.0 Ω max at 0.5 mA - supports predictable load regulation without external compensation. |
| Wide operating voltage range | 14.5–15.1 V nominal - fits 15 V rail stabilization and ±12 V system biasing with margin. |
| Automated assembly compatibility | 5 mm pitch, MHD package - eliminates manual placement in high-volume production. |
| High junction temperature rating | 200°C max - allows deployment in enclosed industrial enclosures without forced cooling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBZ5245B | Zener voltage 15 V ±5%, rd = 17 Ω, Pd = 350 mW, SOD-123 package | SMT-only; lacks low-noise optimization and 400 mW rating | Preferred for space-constrained PCBs where noise is secondary to footprint. |
| Vishay BZX84-C15 | Zener voltage 15 V ±5%, rd = 20 Ω, Pd = 300 mW, SOT-23 package | Higher impedance and lower power; no documented low-noise characterization | Acceptable for general-purpose regulation but unsuitable for precision analog reference roles. |
Compared with MMBZ5245B and BZX84-C15, the HZS15-2LTD-E delivers tighter voltage tolerance, lower dynamic resistance, higher power handling, and verified low-noise performance-making it the only option among the three qualified for metrology-grade reference design.

FAQ
What is the exact zener voltage range specified for HZS15-2LTD-E?
The HZS15-2LTD-E has a guaranteed zener voltage range of 14.5 V to 15.1 V when tested at IZ = 0.5 mA and Ta = 25°C. This ±0.3 V tolerance reflects tighter binning than standard 5% Zeners and supports high-accuracy regulation without post-calibration trimming. The value is confirmed in the Renesas REJ03G0166-0300 datasheet, Page 3.
Does HZS15-2LTD-E have a documented noise specification compared to other Zener diodes?
Yes, the HZS15-2LTD-E datasheet explicitly states its noise level is approximately 1/3 to 1/10 that of the legacy HZ series. This low-noise performance is achieved through optimized planar junction design and is validated across the HZS-L family. For HZS15-2LTD-E, this translates to measurable improvement in SNR-critical applications such as sensor signal conditioning and precision ADC references.
What package type and lead configuration does HZS15-2LTD-E use?
HZS15-2LTD-E uses the MHD package (JEITA code GRZZ0002ZC-A): an axial-leaded, silicon planar diode housing with 2.0 mm body diameter, 26.0 mm length, 0.4 mm lead diameter, and black cathode band marking. It is designed for 5 mm pitch high-speed automatic insertion and complies with standard wave-soldering profiles.
What is the maximum power dissipation and thermal derating behavior of HZS15-2LTD-E?
HZS15-2LTD-E has a maximum power dissipation of 400 mW at Ta = 25°C, with linear derating to zero at Ta = 175°C (per Fig.3). Junction temperature is rated to 200°C. This derating curve enables reliable operation in industrial enclosures up to 70°C ambient when mounted on standard FR-4 PCBs with adequate copper area, as confirmed in the absolute maximum ratings table on Page 2 of the datasheet.
Is HZS15-2LTD-E suitable for automotive or safety-critical applications?
No-HZS15-2LTD-E is classified as a "Standard" quality grade device per Renesas documentation (REJ03G0166-0300, Page 1), intended for computers, office equipment, communications gear, and industrial robots. It is not qualified for automotive, medical life-support, aerospace, or nuclear applications. Use in such contexts requires explicit written consent from Renesas and validation against AEC-Q200 or ISO 26262 requirements, which do not apply to HZS15-2LTD-E.
