Product details
Overview
HZ15-2J-E from Renesas is a silicon planar Zener diode optimized for low-noise voltage regulation in precision analog circuits, with a nominal zener voltage of 14.5–15.1 V, 400 mW power dissipation, 13.0 Ω dynamic resistance at 0.5 mA, and DO-35 glass package. It serves as a stable reference in low-drift power supplies and sensor biasing networks.
For engineers reviewing the HZ15-2J-E datasheet, HZ15-2J-E pinout, HZ15-2J-E application, or HZ15-2J-E equivalent, key selection criteria include zener voltage tolerance (±0.3 V), low noise performance (1/3–1/10 of standard HZ series), temperature coefficient (−0.04 %/°C typical), and DO-35 mechanical compatibility in space-constrained PCB layouts.
Technical Context
This device operates as a two-terminal voltage reference using avalanche breakdown in a planar-diffused silicon junction. Its low dynamic impedance (13.0 Ω) and tight zener voltage tolerance (14.5–15.1 V at 0.5 mA) enable high-accuracy regulation under varying load conditions.
The HZ15-2J-E exhibits a negative temperature coefficient (−0.04 %/°C) and is rated for junction temperatures up to 175°C. It is tested with DC and specified for use in stabilized power supplies where low leakage (<1 μA at VR = 12 V) and minimal noise are critical.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C15LT1G | Zener voltage 14.4–15.6 V (±5%), 300 mW rating, SOT-23 package, higher rd ≈ 30 Ω | SMT-compatible but less stable under thermal cycling due to smaller die and higher tempco (−0.07 %/°C) | Select when board space is constrained and SMT assembly is required; verify thermal derating above 50°C ambient |
| 1N4744A | Zener voltage 13.5–14.5 V (±5%), 1 W rating, DO-41 package, rd ≈ 14 Ω, higher noise than HZ-L series | Higher power handling but 3× higher noise and looser voltage tolerance limit use in precision references | Choose only for non-critical regulation where cost and availability outweigh noise and accuracy requirements |
Compared with BZX84-C15LT1G and 1N4744A, the HZ15-2J-E delivers superior voltage accuracy (±0.3 V vs. ±5%), lower noise (1/3–1/10 of standard HZ), and tighter tempco (−0.04 %/°C), making it optimal for metrology, sensor excitation, and high-resolution analog systems where reference integrity is paramount.

FAQ
What is the exact zener voltage range for HZ15-2J-E?
The HZ15-2J-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 is tighter than standard Zener diodes and supports high-accuracy reference design without post-manufacturing trimming. The HZ15-2J-E achieves this via controlled planar diffusion and screening during production.
Is HZ15-2J-E suitable for low-noise applications?
Yes - the HZ15-2J-E is explicitly engineered for low-noise operation, with noise performance approximately 1/3 to 1/10 that of the legacy HZ series. This is achieved through optimized junction geometry and low-leakage processing. In practice, the HZ15-2J-E contributes negligible broadband noise to precision reference paths, making it ideal for use with high-resolution ADCs and low-noise op-amps.
What is the maximum power dissipation rating for HZ15-2J-E?
The HZ15-2J-E is rated for 400 mW maximum power dissipation at Ta = 25°C. Derating is required above 25°C ambient, following the curve in Figure 3 of the datasheet (REJ03G0182-0300), with zero dissipation at 175°C. At 70°C ambient, usable power drops to ~280 mW. This rating supports robust operation in enclosed industrial enclosures without heatsinking.
Does HZ15-2J-E have a specified temperature coefficient?
Yes - the HZ15-2J-E exhibits a negative temperature coefficient of −0.04 %/°C, as shown in Figure 2 of the datasheet. This value is typical and applies across its 14.5–15.1 V zener voltage range. The coefficient enables predictable voltage drift modeling and facilitates temperature-compensated reference designs when paired with positive-tempco components.
What package type does HZ15-2J-E use, and what are its key dimensions?
HZ15-2J-E uses the DO-35 axial glass package (JEITA code GRZZ0002ZB-A), with orange body color and navy blue cathode band. Key dimensions: body diameter φD = 2.0 mm, overall length L = 26.0 mm, lead spacing E = 4.2 mm. It conforms to SC-40 mechanical standard and weighs 0.13 g. This package supports manual or wave-solder assembly and offers hermetic reliability.
