Product details
Overview
HZ6A2L-J-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 5.45 V (min 5.3 V / max 5.6 V), dynamic resistance of 150 Ω at 0.5 mA, maximum power dissipation of 400 mW, and junction temperature rating up to 175°C - deployed in reference voltage generators and sensor signal conditioning stages.
For engineers reviewing the HZ6A2L-J-E datasheet, HZ6A2L-J-E pinout, HZ6A2L-J-E application, or HZ6A2L-J-E equivalent, key selection criteria include its low-noise performance (1/3–1/10 lower than standard HZ series), DO-35 package compatibility, zener voltage tolerance (±3.5% at 5.45 V), and thermal stability across −55°C to +175°C storage range.
Technical Context
The HZ6A2L-J-E operates as a two-terminal shunt regulator with DC-tested zener characteristics, designed for stable biasing and noise-sensitive reference generation. Its low leakage current (≤1 μA at VR = 2.0 V) and tightly controlled dynamic impedance (150 Ω @ IZ = 0.5 mA) support high-accuracy voltage stabilization in low-current analog front-ends.
Zener voltage temperature coefficient is negative and voltage-dependent - typical γZ ≈ −0.06 %/°C near 5.5 V (per Fig.2), enabling predictable drift compensation in temperature-stable references. The device is not intended for transient suppression or high-current regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.3 V min / 5.6 V max at IZ = 0.5 mA - defines tight 5.45 V ±3.5% regulation window for precision references. |
| Dynamic Resistance (rd) | 150 Ω max at IZ = 0.5 mA - ensures minimal output voltage variation under small load current changes. |
| Power Dissipation (Pd) | 400 mW max at Ta = 25°C - sets absolute thermal limit for continuous DC operation in DO-35 package. |
| Reverse Current (IR) | ≤1 μA max at VR = 2.0 V - guarantees low leakage in high-impedance bias networks. |
| Junction Temperature (Tj) | 175°C max - enables reliable operation in thermally constrained industrial and automotive under-hood environments. |
| Storage Temperature | −55°C to +175°C - supports wide-range handling and long-term reliability in harsh ambient conditions. |
Pinout & Package
Package: DO-35 (JEITA code GRZZ0002ZB-A), glass axial leaded package with orange body and navy blue cathode band; total mass 0.13 g, dimensions per SC-40 standard (φD = 2.0 mm, L = 26.0 mm, E = 4.2 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Cathode) | Zener anode connection point | Connected to higher potential node; reverse-biased operation requires cathode at positive potential relative to anode. |
| 2 (Anode) | Zener cathode connection point | Reference ground or return path; establishes current flow direction during zener conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Noise level | Approximately 1/3–1/10 lower than standard HZ series - directly improves SNR in audio preamps and ADC reference buffers. |
| Zener impedance control | 150 Ω max at 0.5 mA - enables stable regulation even with microamp-level load variations in sensor interfaces. |
| Voltage range coverage | 5.2 V to 38 V available across HZ-L family - allows single-design reuse across multiple supply rail targets without topology change. |
| Thermal robustness | 175°C max junction temperature - supports deployment in engine control units and industrial PLC modules without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C5V6 (ON Semiconductor) | 5.6 V nominal, ±5% tolerance, 150 Ω rd, 500 mW Pd, DO-35 package | Higher power rating but wider voltage tolerance and higher noise vs. HZ6A2L-J-E | Select when higher power margin is required and ±5% VZ tolerance is acceptable. |
| 1N4732A (Vishay) | 5.6 V nominal, ±5% tolerance, 17 Ω rd @ 41 mA, 1 W Pd, DO-41 package | Lower dynamic resistance only at high test current (41 mA); unsuitable for low-current precision use | Choose only for high-current regulation where low rd at ≥20 mA is critical and noise is secondary. |
Compared with BZX55C5V6 and 1N4732A, the HZ6A2L-J-E delivers superior low-noise performance and tighter voltage tolerance at microamp bias currents - making it uniquely suited for precision analog reference and sensor excitation where signal integrity dominates power handling needs.

FAQ
What is the exact zener voltage range specified for HZ6A2L-J-E?
The HZ6A2L-J-E has a guaranteed zener voltage range of 5.3 V minimum to 5.6 V maximum when tested at IZ = 0.5 mA and Ta = 25°C. This corresponds to a nominal value of 5.45 V with ±3.5% tolerance, confirmed in the Renesas datasheet REJ03G0182-0300 Rev.3.00.
Is HZ6A2L-J-E suitable for high-frequency noise filtering applications?
No - the HZ6A2L-J-E is a DC-optimized Zener diode with specified characteristics tested under DC conditions only. It is not characterized for RF impedance or high-frequency noise suppression. Its low-noise advantage applies to broadband analog reference stability, not AC filtering. For RF decoupling, dedicated bypass capacitors or TVS diodes should be used alongside HZ6A2L-J-E.
What is the cathode identification method on the HZ6A2L-J-E package?
The HZ6A2L-J-E uses a navy blue cathode band located on the orange-glass DO-35 body. Pin 1 (cathode) is the lead adjacent to this band; Pin 2 (anode) is the opposite lead. This marking aligns with JEITA standard GRZZ0002ZB-A and is visible under standard visual inspection.
Can HZ6A2L-J-E replace standard HZ-series Zener diodes directly?
Yes - the HZ6A2L-J-E shares identical DO-35 packaging, pinout, and mechanical footprint with legacy HZ-series diodes. However, due to its significantly lower noise (1/3–1/10 of HZ series) and tighter VZ tolerance, it provides immediate performance uplift in noise-sensitive designs without PCB changes, provided thermal and current limits remain within spec.
What is the maximum allowable reverse current for HZ6A2L-J-E before regulation degrades?
The HZ6A2L-J-E specifies ≤1 μA maximum reverse current (IR) at VR = 2.0 V. Regulation integrity is maintained up to its rated zener test current of 0.5 mA. Operation above 0.5 mA is not characterized in the datasheet and may increase dynamic resistance and temperature-induced drift - sustained operation should remain within 0.1–0.5 mA for optimal HZ6A2L-J-E performance.
