Product details
Overview
HZS15-3LTA-E from Renesas Electronics is a silicon planar Zener diode optimized for low-noise voltage regulation in precision analog and stabilized power supply circuits, with a nominal zener voltage of 14.9–15.5 V, dynamic resistance of 13.0 Ω at 0.5 mA test current, and maximum power dissipation of 400 mW in the MHD package.
For engineers reviewing the HZS15-3LTA-E datasheet, HZS15-3LTA-E pinout, HZS15-3LTA-E application, or HZS15-3LTA-E equivalent, this device is selected for noise-sensitive reference design, low-drift biasing, and high-stability DC-DC feedback networks where zener impedance and temperature coefficient directly impact system accuracy.
Technical Context
This Zener diode employs a silicon planar junction structure to achieve low noise (≈1/3–1/10 that of the legacy HZ series), low leakage current (<1 μA at VR = 2.0 V), and tight zener voltage tolerance across its 14.9–15.5 V range. Its design targets stable DC reference generation under varying load and temperature conditions.
The device operates with a zener voltage temperature coefficient of approximately +0.04 %/°C (or +6.0 mV/°C) near 15 V, confirmed by Figure 2 in REJ03G0166-0300 Rev.3.00, and maintains low dynamic impedance (13.0 Ω) at IZ = 0.5 mA - critical for minimizing output ripple in shunt-regulated supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 14.9–15.5 V at IZ = 0.5 mA - defines precise shunt regulation point for 15 V reference designs |
| Dynamic Resistance (rd) | 13.0 Ω 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 = 2.0 V - reduces error current in high-impedance reference nodes |
| Junction Temperature (Tj) | 200 °C - enables reliable operation in thermally demanding industrial environments |
| Noise Level | ≈1/3–1/10 of HZ-series diodes - directly improves SNR in audio preamps and sensor signal chains |
Pinout & Package
The HZS15-3LTA-E is housed in the MHD package (JEITA code GRZZ0002ZC-A), a radial leaded, epoxy-molded case with 2.0 mm diameter leads and 26.0 mm body length, designed for 5 mm-pitch high-speed automatic insertion.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener voltage reference node | Connected to regulated output or feedback node; polarity must be observed to maintain reverse-bias operation |
| 2 (Anode) | Current return path | Typically tied to ground or common rail; forms shunt path for excess current during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise Zener operation | Reduces broadband voltage noise in precision references - critical for 16-bit+ ADC/DAC biasing |
| Tight zener voltage tolerance | ±0.3 V window (14.9–15.5 V) enables accurate 15 V rail stabilization without post-regulation trimming |
| Low dynamic impedance | 13.0 Ω at 0.5 mA minimizes load-induced drift in feedback loops of linear regulators |
| High thermal robustness | 200 °C max junction temperature supports use in enclosed industrial enclosures with ambient up to 125 °C |
| Automated assembly compatibility | MHD package with 5 mm pitch meets IPC-J-STD-020 standards for wave and reflow soldering |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C15LT1G (ON Semiconductor) | 15 V nominal, 300 mW Pd, 20 Ω rd, SOT-23 package | SMT-only; higher dynamic resistance increases regulation error in high-precision analog | Select when board space is constrained and noise sensitivity is moderate |
| 1N4744A (onsemi) | 15 V nominal, 1 W Pd, 16 Ω rd, DO-41 package | Higher power but larger footprint and 3× higher noise than HZS15-3LTA-E | Choose only if >400 mW dissipation is required and low-noise performance is secondary |
Compared with BZX84-C15LT1G and 1N4744A, the HZS15-3LTA-E delivers superior noise performance and tighter voltage tolerance in a through-hole MHD package optimized for automated insertion - making it preferred for industrial analog signal chains where long-term stability and low drift outweigh miniaturization needs.

FAQ
What is the zener voltage tolerance of HZS15-3LTA-E?
The HZS15-3LTA-E has a specified zener voltage range of 14.9 V to 15.5 V at IZ = 0.5 mA, corresponding to a ±0.3 V absolute tolerance. This tight window supports accurate 15 V regulation without external trimming and is confirmed in Table on page 3 of REJ03G0166-0300 Rev.3.00. The HZS15-3LTA-E achieves this via process-controlled planar junction doping.
Does HZS15-3LTA-E meet RoHS requirements?
Yes, the HZS15-3LTA-E complies with the EU RoHS Directive (2011/65/EU) as confirmed by Renesas' environmental compliance documentation. Lead-free solderability and halogen-free molding compound are standard for this MHD-packaged device, and full material declarations are available upon request from Renesas or Aetrix Electronics for HZS15-3LTA-E.
What is the maximum reverse leakage current for HZS15-3LTA-E?
The HZS15-3LTA-E exhibits a maximum reverse leakage current of 1 μA at VR = 2.0 V, per the Electrical Characteristics table on page 3 of REJ03G0166-0300 Rev.3.00. This low leakage preserves accuracy in high-impedance reference nodes and reduces quiescent error current in precision feedback paths used with the HZS15-3LTA-E.
Can HZS15-3LTA-E be used in surface-mount designs?
No - the HZS15-3LTA-E uses the radial-leaded MHD package (JEITA GRZZ0002ZC-A), which is designed exclusively for through-hole mounting and 5 mm-pitch automated insertion. It is not compatible with SMT reflow or pick-and-place processes. For SMT alternatives, consider the BZX84-C15LT1G, but note its higher noise and dynamic resistance versus the HZS15-3LTA-E.
What is the zener voltage temperature coefficient of HZS15-3LTA-E?
The HZS15-3LTA-E has a zener voltage temperature coefficient of +0.04 %/°C (approximately +6.0 mV/°C), as shown in Figure 2 of REJ03G0166-0300 Rev.3.00. This positive, low-drift coefficient ensures predictable, monotonic voltage shift over temperature - essential for maintaining accuracy in industrial environments where the HZS15-3LTA-E operates from −55 °C to +175 °C storage.
