Product details
Overview
HZ5.6BPTN-E from Renesas is a silicon planar Zener diode optimized for low-noise voltage regulation in precision analog circuits, featuring a nominal zener voltage of 5.6 V, dynamic resistance of 80 Ω at 0.5 mA, maximum power dissipation of 400 mW, and junction temperature rating up to 175°C. It is used in stabilized power supplies, reference voltage sources, and noise-sensitive instrumentation.
For engineers reviewing the HZ5.6BPTN-E datasheet, HZ5.6BPTN-E pinout, HZ5.6BPTN-E application, or HZ5.6BPTN-E equivalent, key selection criteria include zener voltage tolerance (±0.3 V), low noise performance (1/3–1/10 of standard HZ series), DO-35 package compatibility, and thermal stability across −55°C to +175°C storage range.
Technical Context
The HZ5.6BPTN-E operates as a two-terminal voltage reference device with DC-tested zener characteristics, designed for stable reverse-bias regulation under controlled current conditions. Its low dynamic impedance (80 Ω) and tight VZ tolerance support high-accuracy biasing in analog front-ends and sensor signal conditioning.
It exhibits a negative temperature coefficient near 5.6 V (≈−2 mV/°C), minimizing drift in mid-range zener applications. The device is rated for 400 mW power dissipation at 25°C ambient, derating linearly above 25°C per the published curve (Fig.3).
Key Specifications

| Power Dissipation (Pd) | 400 mW at Ta = 25°C - supports compact PCB layouts without forced cooling |
| Reverse Leakage (IR) | ≤1 μA at VR = 2.0 V - enables ultra-low quiescent current in battery-powered 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 |
|---|---|---|---|
| BZX55C5V6 (ON Semiconductor) | VZ = 5.6 V ±5%, rd = 40 Ω typical, Pd = 500 mW, DO-35 package | Higher power rating but wider VZ tolerance and no low-noise specification | Select when absolute power handling >400 mW is required and noise is secondary |
| MMSZ5232BS (Diodes Inc.) | VZ = 5.6 V ±5%, rd = 15 Ω typical, SOD-123 package, 500 mW rating | Surface-mount only; lower rd but uncharacterized noise performance vs. HZ-L series | Select for automated assembly where DO-35 axial lead is incompatible with layout |
Compared with BZX55C5V6 and MMSZ5232BS, the HZ5.6BPTN-E delivers verified low-noise operation and tighter VZ tolerance (±0.3 V) essential for metrology-grade references, while maintaining legacy DO-35 through-hole compatibility and 175°C thermal capability.

FAQ
What is the exact zener voltage range specified for HZ5.6BPTN-E?
The HZ5.6BPTN-E has a guaranteed zener voltage range of 5.6 V minimum to 5.9 V maximum at IZ = 0.5 mA and Ta = 25°C. This 0.3 V tolerance window reflects its B-grade binning within the HZ-L family and is tighter than standard commercial Zeners, supporting high-accuracy reference designs without post-manufacture trimming.
Is HZ5.6BPTN-E suitable for surface-mount assembly?
No, the HZ5.6BPTN-E uses a DO-35 glass axial package with 26 mm lead length and is designed exclusively for through-hole mounting. Its orange body and navy blue cathode band are optimized for manual or wave-solder processes. For SMT alternatives, consider MMSZ5232BS or BZX84-C5V6, though neither matches the documented low-noise performance of HZ5.6BPTN-E.
How does the noise performance of HZ5.6BPTN-E compare to standard Zener diodes?
The HZ5.6BPTN-E achieves approximately 1/3 to 1/10 the noise level of conventional HZ-series Zeners due to proprietary silicon planar processing and optimized junction geometry. This is validated in Renesas' characterization data and makes it suitable for applications where broadband noise below 100 kHz would otherwise degrade signal integrity - such as in precision DAC reference buffers or low-level sensor amplifiers.
What is the maximum allowable reverse current before breakdown instability occurs in HZ5.6BPTN-E?
The HZ5.6BPTN-E is characterized up to IZ = 0.5 mA for dynamic resistance and voltage specification. While it can sustain higher currents briefly, operation beyond 10 mA risks exceeding the 400 mW power limit and inducing thermal runaway. For stable regulation, design target current between 1 mA and 5 mA using appropriate series resistance, referencing the derating curve in Figure 3 of REJ03G0182-0300.
Does HZ5.6BPTN-E have a specified temperature coefficient, and how does it affect circuit accuracy?
Yes - at 5.6 V, the HZ5.6BPTN-E exhibits a zener voltage temperature coefficient (γZ) near −2 mV/°C (≈−0.036 %/°C), as shown in Figure 2 of the datasheet. This negative coefficient partially compensates for positive TC components in associated circuitry, enabling improved overall thermal stability in compensated reference designs - especially valuable in unregulated ambient environments.
