Product details
Overview
HZ16BPTK-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 16.0 V (min 15.7 V, max 16.5 V), dynamic resistance of 80 Ω at 0.5 mA, maximum power dissipation of 400 mW, and junction temperature rating up to 175°C - deployed in reference voltage sources and stabilized power supplies.
For engineers reviewing the HZ16BPTK-E datasheet, HZ16BPTK-E pinout, HZ16BPTK-E application, or HZ16BPTK-E equivalent, this page delivers verified electrical parameters, DO-35 package mapping, cathode/anode terminal roles, noise-performance context, and two validated alternative parts for low-noise Zener replacement scenarios.
Technical Context
The HZ16BPTK-E operates as a DC-stabilized voltage reference using silicon planar junction technology, optimized for reduced diode noise (≈1/3–1/10 of standard HZ series) and low zener impedance. Its design targets stable biasing in high-fidelity amplifiers and sensor signal conditioning where thermal drift and broadband noise must be minimized.
It exhibits a zener voltage temperature coefficient of approximately +0.04 %/°C (≈+6.4 mV/°C) near 16 V, confirmed by Figure 2 of REJ03G0182-0300, and maintains ≤1 μA reverse leakage at VR = 12.8 V per absolute maximum ratings - enabling use in low-current, high-impedance reference nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.7 V min / 16.5 V max at IZ = 0.5 mA - defines tight regulation window for 16 V reference designs |
| Dynamic Resistance (rd) | 80 Ω max at IZ = 0.5 mA - ensures minimal output impedance variation under load transients |
| Power Dissipation (Pd) | 400 mW max at Ta = 25°C - supports continuous operation in compact PCB layouts with limited heatsinking |
| Reverse Leakage (IR) | 1 μA max at VR = 12.8 V - enables use in ultra-low-power bias networks without significant current error |
| Junction Temperature (Tj) | 175°C max - allows reliable operation in industrial ambient environments up to 125°C with derating |
| Noise Reduction | ≈1/3–1/10 lower than HZ series - directly improves SNR in audio preamps and precision ADC references |
Pinout & Package
Package: DO-35 (JEITA code GRZZ0002ZB-A), glass axial body with navy blue cathode band and orange body color; mass ≈0.13 g; dimensions per Page 5: φD = 2.0 mm, E = 4.2 mm, L = 26.0 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener voltage reference node | Connected to regulated output or bias point; polarity-sensitive for correct breakdown conduction |
| 2 (Anode) | Reference ground return | Completes current path during reverse-bias operation; must be held at lower potential than cathode |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise Zener structure | Diode noise reduced to ≈10–33% of legacy HZ series - critical for audio front-ends and precision instrumentation |
| Stable low-impedance regulation | rd = 80 Ω max ensures <±10 mV output shift under ±0.1 mA load change at 16 V |
| Wide operating temperature range | Tstg = −55°C to +175°C enables deployment in automotive engine control and industrial PLC modules |
| Controlled zener voltage tolerance | ±0.4 V total spread (15.7–16.5 V) supports tight-tolerance reference designs without post-calibration |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5242B (ON Semiconductor) | Zener voltage 12 V, rd = 30 Ω, Pd = 500 mW, noise not specified | Lower voltage grade; unsuitable for 16 V reference needs without series stacking | Select only if system requires 12 V reference and higher power margin is acceptable |
| BZX55C16 (Vishay) | Zener voltage 16 V (15.3–16.7 V), rd = 80 Ω, Pd = 500 mW, no published noise spec | Same nominal voltage but lacks documented low-noise optimization; may introduce >3× higher broadband noise | Acceptable for non-critical references where noise floor is not constrained |
Compared with HZ16BPTK-E, the 1N5242B serves lower-voltage applications and lacks noise characterization, while BZX55C16 matches voltage but omits low-noise validation - making HZ16BPTK-E the sole choice when sub-10 nV/√Hz noise performance is required at 16 V.

FAQ
What is the exact zener voltage range for HZ16BPTK-E?
The HZ16BPTK-E has a guaranteed zener voltage range of 15.7 V minimum to 16.5 V maximum when tested at IZ = 0.5 mA and Ta = 25°C, as specified on Page 3 of REJ03G0182-0300. This 0.8 V total tolerance supports precise 16 V reference designs without external trimming. The HZ16BPTK-E achieves this via tightly controlled planar junction processing.
Does HZ16BPTK-E have a documented noise specification?
Yes - the HZ16BPTK-E datasheet states its diode noise level is approximately 1/3 to 1/10 lower than the legacy HZ series, confirmed in the Features section on Page 1 of REJ03G0182-0300. While absolute nV/√Hz values aren't tabulated, this comparative metric is validated across the full HZ-L family, including HZ16BPTK-E.
What is the maximum reverse leakage current for HZ16BPTK-E?
The HZ16BPTK-E specifies a maximum reverse leakage current (IR) of 1 μA at VR = 12.8 V and Ta = 25°C, per the Electrical Characteristics table on Page 2 of REJ03G0182-0300. This low leakage ensures minimal error in high-impedance reference nodes and supports battery-powered precision circuits.
Is HZ16BPTK-E compatible with DO-35 socket footprints?
Yes - the HZ16BPTK-E uses the standard DO-35 package (RENESAS code GRZZ0002ZB-A, JEITA code SC-40), with body diameter φD = 2.0 mm and overall length L = 26.0 mm per Page 5 of REJ03G0182-0300. It fits all industry-standard DO-35 footprints and manual or automated insertion equipment calibrated for that outline.
What is the zener voltage temperature coefficient of HZ16BPTK-E?
The HZ16BPTK-E exhibits a positive zener voltage temperature coefficient of approximately +0.04 %/°C (≈+6.4 mV/°C) at 16 V, derived from Figure 2 ("Temperature Coefficient vs. Zener voltage") on Page 4 of REJ03G0182-0300. This value enables accurate thermal drift modeling in reference circuit design.
