Product details
Overview
HZ10CPTK-E from Renesas is a silicon planar Zener diode engineered for low-noise voltage regulation in precision analog circuits, featuring a nominal zener voltage of 10 V (min 9.9 V, max 10.3 V), dynamic resistance of 8 Ω at 5 mA, maximum power dissipation of 400 mW, and reverse leakage current ≤1 μA at 7.5 V - deployed in reference voltage generators for data converters and sensor signal conditioning.
For engineers reviewing the HZ10CPTK-E datasheet, HZ10CPTK-E pinout, HZ10CPTK-E application, or HZ10CPTK-E equivalent, key selection criteria include zener voltage tolerance (±3%), temperature coefficient (−0.02 %/°C typical), low noise performance (≈1/3–1/10 of standard HZ series), and DO-35 package compatibility with through-hole PCB layouts requiring stable 10 V references.
Technical Context
The HZ10CPTK-E operates as a two-terminal shunt regulator with DC-tested zener characteristics, optimized for low-noise operation via reduced junction area and refined diffusion process. Its zener voltage is specified at IZ = 0.5 mA (min) and 1 mA (max), with dynamic resistance measured at IZ = 5 mA under DC conditions.
Designed for ambient temperatures from −55°C to +175°C, it maintains stable regulation across industrial environments, with a negative temperature coefficient of −0.02 %/°C near 10 V - enabling predictable drift compensation in high-stability references.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.9 V min / 10.3 V max at IZ = 0.5 mA - ensures tight 10 V reference with ±3% tolerance for ADC/DAC biasing |
| Dynamic Resistance (rd) | 8 Ω max at IZ = 5 mA - minimizes output impedance variation under load transients |
| Power Dissipation (Pd) | 400 mW max at Ta = 25°C - supports continuous operation in compact through-hole designs without forced cooling |
| Reverse Leakage (IR) | ≤1 μA at VR = 7.5 V - preserves accuracy in high-impedance reference nodes |
| Junction Temperature (Tj) | 175°C max - enables reliable operation in automotive under-hood and industrial control enclosures |
| Temperature Coefficient (γZ) | −0.02 %/°C typical at 10 V - allows predictable thermal drift modeling in precision voltage sources |
Pinout & Package
Package: DO-35 glass axial lead package (JEITA code GRZZ0002ZB-A, Renesas code SC-40), orange body with navy blue cathode band, mass 0.13 g, dimensions φD = 2.0 mm, L = 26.0 mm, E = 4.2 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener voltage reference node | Connected to regulated output; polarity must be observed to maintain reverse-bias conduction |
| 2 (Anode) | Current return path | Connected to ground or lower potential; completes shunt regulation loop with series resistor |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise zener operation | Diode noise level ≈1/3–1/10 that of standard HZ series - critical for audio preamps and high-resolution sensor front-ends |
| Stable low-impedance regulation | rd = 8 Ω max at 5 mA - reduces sensitivity to supply ripple and load-induced voltage sag |
| Wide operating temperature range | Tstg = −55°C to +175°C - supports deployment in engine control units and downhole instrumentation |
| Precision voltage tolerance | ±3% VZ at 10 V - eliminates need for post-calibration trimming in factory-set references |

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 |
|---|---|---|---|
| 1N4740A | Zener voltage 10 V ±5%, rd = 20 Ω, Pd = 1 W, DO-41 package | Higher power but larger footprint and looser tolerance; higher noise than HZ10CPTK-E | Prefer when higher power margin is required and board space permits DO-41; avoid where low-noise or tight tolerance is critical |
| BZX85C10 | Zener voltage 10 V ±5%, rd = 15 Ω, Pd = 1.3 W, DO-41 package | Higher power and wider tolerance; no documented low-noise optimization | Select for general-purpose regulation where cost and availability outweigh noise and precision requirements |
Compared with 1N4740A and BZX85C10, the HZ10CPTK-E delivers tighter voltage tolerance (±3% vs. ±5%), lower dynamic resistance (8 Ω vs. ≥15 Ω), and verified low-noise performance - making it optimal for precision analog signal chains where reference stability and spectral purity are design-critical.

FAQ
What is the exact zener voltage range for HZ10CPTK-E?
The HZ10CPTK-E has a guaranteed zener voltage range of 9.9 V minimum to 10.3 V maximum when tested at IZ = 0.5 mA, corresponding to a ±3% tolerance around the nominal 10 V rating. This specification is confirmed in the Renesas datasheet REJ03G0182-0300 Rev.3.00 and applies strictly to the HZ10CPTK-E variant within the HZ-L Series.
Is HZ10CPTK-E compatible with standard DO-35 footprint layouts?
Yes, HZ10CPTK-E uses the DO-35 glass axial package (JEITA code GRZZ0002ZB-A) with standardized dimensions: body diameter 2.0 mm, length 26.0 mm, and lead spacing 4.2 mm. It is mechanically and solder-process compatible with all PCB footprints designed for DO-35 components, including those used for legacy HZ-series diodes.
Does HZ10CPTK-E have a documented low-noise characteristic?
Yes - the HZ-L Series datasheet explicitly states that HZ10CPTK-E exhibits diode noise approximately 1/3 to 1/10 lower than the standard HZ series. This low-noise performance is achieved through process optimization and is validated for use in audio preamplifiers and high-resolution data acquisition systems where spectral purity is essential.
What is the maximum allowable reverse current before breakdown for HZ10CPTK-E?
The HZ10CPTK-E is rated for reverse leakage current ≤1 μA at VR = 7.5 V, per its Electrical Characteristics table. This value reflects the maximum off-state current prior to reaching the zener knee; operation above this voltage initiates controlled breakdown and zener conduction, governed by the series current-limiting resistor.
Can HZ10CPTK-E be used in automotive under-hood applications?
Yes - HZ10CPTK-E supports junction temperatures up to 175°C and storage temperatures from −55°C to +175°C. Its DO-35 glass package and specified thermal performance make it suitable for engine control unit references and sensor conditioning circuits located in high-temperature automotive environments, provided derating per Fig.3 (Power Dissipation vs. Ambient Temperature) is applied.
