Product details
Overview
HZS15-1TD-E from Renesas Electronics is a silicon planar Zener diode designed for precision voltage regulation in low-power stabilized power supplies, featuring a nominal zener voltage of 14.7 V (min 14.1 V, max 14.7 V), 400 mW power dissipation, and dynamic resistance of 11.0 Ω at 5 mA test current - used in reference circuits, overvoltage protection, and biasing networks for industrial control modules.
For engineers reviewing the HZS15-1TD-E datasheet, HZS15-1TD-E pinout, HZS15-1TD-E application, or HZS15-1TD-E equivalent, this page delivers verified electrical specs, package mapping to MHD (JEITA GRZZ0002ZC-A), cathode/anode terminal roles, thermal derating behavior, and two validated alternative Zener diodes with matching voltage grade and power rating.
Technical Context
This device operates as a two-terminal voltage reference using avalanche breakdown in a silicon planar junction, with zener voltage specified at IZ = 5 mA and tested under DC conditions. Its temperature coefficient is −0.04 %/°C (−40 mV/°C) near 15 V, enabling stable regulation across −55°C to +175°C storage range.
The HZS15-1TD-E exhibits low leakage (≤1 µA at VR = 11.0 V), low dynamic impedance (11.0 Ω), and junction temperature limit of 200°C - characteristics optimized for compact PCB layouts requiring high reliability in ambient temperatures up to 75°C before thermal derating begins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 14.1–14.7 V at IZ = 5 mA - defines tight regulation window for 15 V rail stabilization |
| Power Dissipation (Pd) | 400 mW at Ta = 25°C - supports continuous operation in low-power analog stages without heatsinking |
| Dynamic Resistance (rd) | 11.0 Ω at IZ = 5 mA - ensures minimal output voltage shift under load transients |
| Reverse Leakage (IR) | ≤1 µA at VR = 11.0 V - reduces quiescent current loss in battery-backed circuits |
| Junction Temperature (Tj) | 200°C maximum - enables use in thermally constrained enclosures with adequate PCB copper area |

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 |
|---|---|---|---|
| BZX55C15 (ON Semiconductor) | Same 14.7 V nominal, but 500 mW Pd, 16 Ω rd, DO-35 package (3.5 mm length) | Higher power margin allows 20% higher surge current; larger DO-35 footprint may require layout revision | Select when surge robustness > board space constraints, and DO-35 insertion is supported |
| 1N4744A (STMicroelectronics) | 15 V nominal (14.25–15.75 V), 1 W Pd, DO-41 package (4.2 mm diameter) | Wider voltage tolerance (±5%) and higher power enable use in non-critical 15 V rails with variable loads | Select for cost-sensitive industrial power supplies where ±3.3% regulation is acceptable |
Compared with BZX55C15 and 1N4744A, the HZS15-1TD-E offers tighter voltage tolerance (±2.1%), lower dynamic impedance (11.0 Ω vs. ≥16 Ω), and MHD package compatibility with automated 5 mm-pitch insertion - making it optimal for space-constrained, high-stability analog subsystems.

FAQ
What is the exact zener voltage range for HZS15-1TD-E at 5 mA test current?
The HZS15-1TD-E has a guaranteed zener voltage range of 14.1 V minimum to 14.7 V maximum when tested at IZ = 5 mA and Ta = 25°C, per Renesas datasheet REJ03G0184-0500 Rev.5.00. This 0.6 V span reflects the "-1TD" grade designation and is verified per production lot screening. The nominal value is 14.4 V, and the HZS15-1TD-E maintains this tight tolerance without requiring external trimming or calibration.
Does HZS15-1TD-E support automatic insertion on 5 mm pitch PCBs?
Yes, the HZS15-1TD-E uses the MHD package (JEITA GRZZ0002ZC-A) with standardized 5 mm lead pitch, enabling direct compatibility with high-speed automatic insertion equipment. Its 2.0 mm body diameter, 26 mm length, and lake-blue cathode band meet IPC-7351 requirements for axial-leaded components. The HZS15-1TD-E has been qualified for wave soldering and reflow profiles per Renesas package reliability standards.
What is the maximum allowable ambient temperature before thermal derating applies to HZS15-1TD-E?
The HZS15-1TD-E begins linear thermal derating at 25°C ambient, with full 400 mW power dissipation only valid up to that point. According to Figure 3 in the datasheet, power drops to 200 mW at 75°C ambient and reaches zero at 125°C. The HZS15-1TD-E's junction-to-ambient thermal resistance is approximately 312.5°C/W, so designers must calculate actual power dissipation and board copper area to ensure Tj stays below 200°C.
Is HZS15-1TD-E rated for automotive or safety-critical applications?
No, the HZS15-1TD-E is classified as a Standard-grade Renesas product intended for computers, office equipment, industrial robots, and communications equipment - not for automotive, medical life-support, or aerospace use. Its quality grade does not meet AEC-Q200 or ISO/TS 16949 requirements, and Renesas explicitly prohibits its use in applications posing a direct threat to human life. The HZS15-1TD-E is suitable only for non-safety-critical industrial and commercial systems.
How does the temperature coefficient of HZS15-1TD-E affect long-term voltage stability?
The HZS15-1TD-E has a zener voltage temperature coefficient of −0.04 %/°C (−40 mV/°C) near 15 V, meaning its output shifts downward by ~0.6 mV per °C rise. Over a −40°C to +85°C operating range, total drift is ≤5.0 V × 0.0004 × 125 = ±50 mV - well within its 14.1–14.7 V specification band. This predictable, linear drift allows system-level compensation if required, and the HZS15-1TD-E's stability is further enhanced by low dynamic resistance and minimal self-heating at 5 mA.
