Product details
Overview
HZ15CPTN-E from Renesas is a silicon planar Zener diode engineered for low-noise voltage regulation in precision analog circuits, with a nominal zener voltage of 15.2 V (min 14.9 V, max 15.5 V), dynamic resistance of 13.0 Ω at 0.5 mA test current, maximum power dissipation of 400 mW, and junction temperature rating up to 175°C - deployed in reference supplies for ADCs and sensor signal conditioning.
For engineers reviewing the HZ15CPTN-E datasheet, HZ15CPTN-E pinout, HZ15CPTN-E application, or HZ15CPTN-E equivalent, key selection criteria include zener voltage tolerance (±2.0% typical), low noise performance (1/3–1/10 of standard HZ series), temperature coefficient (−0.04 %/°C at ~15 V), DO-35 package compatibility, and thermal derating behavior above 25°C ambient.
Technical Context
The HZ15CPTN-E operates as a two-terminal shunt regulator with DC-tested zener breakdown characteristics, optimized for stable biasing in low-current (<1 mA) precision references where noise floor and thermal drift are critical. Its planar construction ensures consistent junction geometry and reproducible rd and γZ behavior across production lots.
Designed for operation at IZ = 0.5 mA, it delivers 13.0 Ω dynamic impedance and exhibits a negative temperature coefficient of −0.04 %/°C - enabling predictable compensation in multi-diode reference strings and reducing output drift in temperature-sensitive instrumentation front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 14.9 V min to 15.5 V max at IZ = 0.5 mA - defines tight 2.0% tolerance band for stable reference generation |
| Dynamic Resistance (rd) | 13.0 Ω max at IZ = 0.5 mA - ensures minimal output voltage variation under load transients |
| Power Dissipation (Pd) | 400 mW max at Ta = 25°C - supports continuous operation in compact PCB layouts with limited heatsinking |
| Junction Temperature (Tj) | 175°C max - enables reliable use in industrial environments with elevated ambient temperatures |
| Reverse Leakage (IR) | 1 μA max at VR = 12.0 V - minimizes error current in high-impedance reference nodes |
| Temperature Coefficient (γZ) | −0.04 %/°C - provides predictable, linear drift for calibration-aware designs |
Pinout & Package
Package: DO-35 glass axial leaded package (JEITA code GRZZ0002ZB-A, Renesas code SC-40), orange body color, navy blue cathode band. Dimensions: φD = 2.0 mm, L = 26.0 mm, E = 4.2 mm; mass ≈ 0.13 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | High-impedance reference node connection | Connected to regulated output rail; polarity must be observed to avoid forward conduction |
| 2 (Anode) | Ground or current-sink return path | Biased via series resistor to establish IZ; determines operating point and thermal stability |
Key Features
| Feature | Design Value |
|---|---|
| Noise reduction | Diode noise level ≈ 1/3–1/10 that of standard HZ series - directly improves SNR in precision amplifiers and ADC references |
| Low dynamic impedance | 13.0 Ω at 0.5 mA - maintains regulation accuracy under small-signal load variations without external buffering |
| Wide zener voltage range support | Part of HZ-L family spanning 5.2 V to 38 V - allows standardized design reuse across multiple supply rails |
| Thermal stability | −0.04 %/°C tempco at 15 V - enables predictable drift compensation in multi-stage references |
| Robust reliability | 175°C max junction temperature and −55°C to +175°C storage range - suitable for extended-life industrial deployments |
Applications
| High-Precision ADC Reference | Low-Noise Sensor Biasing |
|---|---|
Use Scenario: Providing stable 15 V reference for 24-bit delta-sigma ADCs in weigh-scale and strain-gauge measurement systems. IC Role / Device Role / Timing Role: Shunt voltage reference establishing exact input full-scale range and offset null point. Use Value: Low 13.0 Ω rd and sub-μA leakage minimize gain/offset drift; low noise prevents quantization uncertainty in LSB resolution. |
Use Scenario: Biasing bridge-type pressure sensors and RTD front-ends where excitation stability dictates measurement repeatability. IC Role / Device Role / Timing Role: Precision current-source companion, setting constant IEXC via series resistor and regulated VZ. Use Value: Tight 14.9–15.5 V tolerance and −0.04 %/°C tempco ensure <±0.02% excitation drift over −40°C to +85°C. |
| Calibration-Grade Instrumentation | Industrial Analog Signal Conditioning |
Use Scenario: Embedded calibration reference in portable multimeters and handheld DMMs requiring traceable voltage standards. IC Role / Device Role / Timing Role: Primary voltage standard against which internal DACs and amplifiers are trimmed during factory calibration.

IC Role / Device Role / Timing Role: Local shunt regulator supplying clean ±15 V analog sections independent of noisy digital supply domains. Use Value: 400 mW Pd and 175°C Tj rating support uninterrupted operation in sealed enclosures at 70°C ambient. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4744A | Zener voltage 14.0–15.0 V (±5%), rd = 14 Ω, no specified low-noise optimization, DO-41 package | Higher voltage tolerance and noise floor limit use in 24-bit systems; larger DO-41 footprint requires layout change | Select only when cost sensitivity outweighs precision and noise requirements; verify thermal derating at target ambient |
| BZX84-C15 | Zener voltage 14.3–15.7 V (±5%), rd = 30 Ω, SOT-23 surface-mount, rated 300 mW | Higher impedance and lower power rating reduce regulation margin in high-precision, high-stability contexts | Prefer for space-constrained PCBs where 0.5% absolute accuracy is sufficient and noise is not critical |
Compared with 1N4744A and BZX84-C15, HZ15CPTN-E delivers tighter voltage tolerance (±2.0% vs. ±5%), lower dynamic impedance (13.0 Ω vs. ≥14 Ω), and documented low-noise performance - making it the preferred choice for metrology-grade references where long-term stability and SNR are design-critical.

FAQ
What is the zener voltage tolerance of HZ15CPTN-E?
The HZ15CPTN-E has a zener voltage range of 14.9 V to 15.5 V at IZ = 0.5 mA, corresponding to a ±2.0% tolerance about the nominal 15.2 V value. This tight specification is confirmed in the Renesas REJ03G0182-0300 datasheet, Page 3, and supports high-accuracy reference design without post-manufacturing trimming. The HZ15CPTN-E achieves this via controlled planar junction processing and binning.
Does HZ15CPTN-E support low-noise operation?
Yes - the HZ15CPTN-E is explicitly characterized as a low-noise Zener diode, with noise performance approximately 1/3 to 1/10 that of the standard HZ series. This is stated in the "Features" section of the Renesas datasheet (Page 1) and results from optimized silicon planar structure and low-leakage fabrication. For HZ15CPTN-E, this enables use in 24-bit ADC references where noise-induced quantization error must be minimized.
What package type does HZ15CPTN-E use?
HZ15CPTN-E uses the DO-35 glass axial package (JEITA code GRZZ0002ZB-A, Renesas SC-40), with orange body color and navy blue cathode band. Dimensions are φD = 2.0 mm, L = 26.0 mm, E = 4.2 mm. This through-hole package is compatible with legacy automated insertion equipment and provides robust thermal coupling to PCB copper for passive cooling.
What is the maximum power dissipation for HZ15CPTN-E?
The HZ15CPTN-E has a maximum power dissipation (Pd) of 400 mW at Ta = 25°C, as specified in the Absolute Maximum Ratings table (Page 2). Derating is required above 25°C ambient per the curve in Figure 3 (Page 4); at 70°C ambient, usable power drops to ~280 mW. This rating supports continuous operation in industrial control modules without forced airflow.
Is HZ15CPTN-E suitable for high-temperature environments?
Yes - the HZ15CPTN-E is rated for junction temperatures up to 175°C and storage temperatures from −55°C to +175°C. Its silicon planar construction and glass DO-35 package provide proven reliability in extended-temperature industrial applications such as motor drive feedback circuits and downhole sensor interfaces. The HZ15CPTN-E maintains specified VZ and rd performance within its full Tj range.
