Product details
Overview
HZS15-3LTD-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 14.9–15.5 V at 0.5 mA, dynamic resistance of 13.0 Ω, maximum power dissipation of 400 mW, and junction temperature rating up to 200°C. It is widely deployed in stabilized power supplies, sensor excitation circuits, and industrial instrumentation requiring stable, low-drift references.
For engineers reviewing the HZS15-3LTD-E datasheet, HZS15-3LTD-E pinout, HZS15-3LTD-E application, or HZS15-3LTD-E equivalent, key selection criteria include its low-noise performance (≈1/3–1/10 of HZ series), tight zener voltage tolerance, low leakage current (<1 μA at VR = 12 V), and suitability for high-reliability 5 mm-pitch automated insertion in industrial PCB assembly.
Technical Context
This device operates as a two-terminal voltage reference using silicon planar Zener breakdown, with DC-tested zener voltage specification and temperature coefficient behavior typical of mid-voltage Zeners (≈+2.0 mV/°C near 15 V). Its low dynamic impedance ensures minimal output voltage variation under load transients.
The HZS15-3LTD-E is rated for operation across −55°C to +175°C storage temperature and up to 200°C junction temperature, supporting use in thermally demanding environments such as motor control feedback loops and automotive under-hood subsystems where thermal stability is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 14.9–15.5 V at IZ = 0.5 mA - defines stable reference point for regulation or biasing |
| Dynamic Resistance (rd) | 13.0 Ω at IZ = 0.5 mA - determines output impedance and load regulation sensitivity |
| Power Dissipation (Pd) | 400 mW - sets maximum continuous power handling without derating at Ta = 25°C |
| Reverse Leakage (IR) | <1 μA at VR = 12 V - ensures minimal error current in high-impedance reference nodes |
| Junction Temperature (Tj) | 200°C - enables reliable operation in high-ambient industrial or automotive environments |
| Storage Temperature | −55°C to +175°C - supports wide-range logistics and long-term board storage |
Pinout & Package
The HZS15-3LTD-E is housed in the MHD package (JEITA code GRZZ0002ZC-A), a radial-leaded, epoxy-molded diode package with 2.0 mm lead diameter and 26.0 mm body length, designed for 5 mm-pitch automatic insertion.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener cathode terminal | Connected to higher potential node; reverse-biased operation requires positive voltage applied here relative to anode |
| 2 (Anode) | Zener anode terminal | Connected to circuit ground or lower potential; completes reverse-bias path for zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise Zener operation | Diode noise level ≈1/3–1/10 that of legacy HZ series - improves SNR in precision ADC references and sensor signal chains |
| Tight zener voltage tolerance | ±0.3 V window (14.9–15.5 V) at 0.5 mA - reduces calibration burden in factory-trimmed systems |
| Low dynamic impedance | 13.0 Ω - maintains stable output under ±10% load current variation without external buffering |
| High thermal robustness | 200°C max junction temperature - supports uninterrupted operation in enclosed enclosures with limited airflow |
| Automated assembly compatibility | MHD package with 5 mm pitch - enables direct integration into high-volume SMT-compatible through-hole insertion lines |
Applications

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 1N5245B | Zener voltage 15 V ±5%, rd = 17 Ω, Pd = 500 mW, noise not specified | Higher tolerance and unspecified noise performance limit use in metrology-grade designs | Select when cost-sensitive production prioritizes availability over low-noise spec |
| Vishay BZX84-C15 | Zener voltage 15 V ±5%, rd = 20 Ω, Pd = 300 mW, SOT-23 surface-mount | SMT package incompatible with through-hole layouts; lower power rating requires thermal margin review | Choose only for space-constrained PCBs where rework to MHD footprint is impractical |
Compared with 1N5245B and BZX84-C15, the HZS15-3LTD-E delivers tighter voltage tolerance, lower dynamic impedance, and verified low-noise performance-making it the preferred choice for industrial and test equipment where reference stability and signal integrity are design-critical.

FAQ
What is the exact zener voltage range for HZS15-3LTD-E?
The HZS15-3LTD-E has a guaranteed zener voltage range of 14.9 V to 15.5 V when tested at IZ = 0.5 mA and Ta = 25°C. This 0.6 V span reflects the device's grade within the HZS15-xL family and ensures predictable regulation headroom in feedback networks without requiring post-manufacture sorting.
Does HZS15-3LTD-E support high-temperature operation?
Yes, the HZS15-3LTD-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 MHD package enable reliable operation in industrial motor drives and automotive under-hood applications where ambient temperatures exceed 125°C.
How does the noise performance of HZS15-3LTD-E compare to standard Zener diodes?
The HZS15-3LTD-E exhibits approximately 1/3 to 1/10 the noise level of the legacy HZ series Zeners. This low-noise characteristic is achieved via optimized planar junction processing and is especially beneficial in high-resolution data acquisition systems where reference noise directly limits effective bits.
Is HZS15-3LTD-E compatible with automated through-hole insertion equipment?
Yes, the HZS15-3LTD-E uses the MHD package (JEITA code GRZZ0002ZC-A), explicitly designed for 5 mm-pitch high-speed automatic insertion. Its standardized lead spacing, body dimensions, and mass (0.084 g) meet IPC-7351 requirements for pick-and-place and wave solder compatibility.
What is the maximum reverse leakage current for HZS15-3LTD-E?
The HZS15-3LTD-E guarantees reverse leakage current of ≤1 μA at VR = 12 V and Ta = 25°C. This low leakage preserves accuracy in high-impedance reference divider networks and minimizes error contributions in battery-powered sensor nodes with microamp-level quiescent current budgets.
