Product details
Overview
HZM5.6NB2JTR from Renesas Electronics is a silicon epitaxial planar Zener diode designed for precision voltage stabilization in low-power analog and reference circuits, with a nominal zener voltage of 5.67–5.92 V at 5 mA, dynamic resistance of 80 Ω max, power dissipation of 200 mW, and MPAK surface-mount package. It serves as a stable shunt reference in power supply feedback loops, sensor biasing, and ADC reference conditioning.
For engineers reviewing the HZM5.6NB2JTR datasheet, HZM5.6NB2JTR pinout, HZM5.6NB2JTR application, or HZM5.6NB2JTR equivalent, key selection criteria include its B2-grade zener voltage tolerance (±2.5% typical), low temperature coefficient near zero crossing (~0.02 mV/°C at 5.6 V), MPAK footprint compatibility with high-density PCB layouts, and suitability for industrial-grade voltage reference designs requiring stable regulation below 6 V.
Technical Context
The HZM5.6NB2JTR operates as a two-terminal shunt regulator, maintaining a stable reverse-biased breakdown voltage across its cathode-anode terminals under controlled test current (IZ = 5 mA). Its epitaxial planar construction ensures tight voltage distribution and repeatable dynamic resistance (rd ≤ 80 Ω).
Designed for ambient temperatures from –55°C to +150°C, it features a junction temperature limit of 150°C and thermal derating per Fig.3 - power dissipation drops linearly above 25°C ambient. The device exhibits minimal voltage drift over temperature due to its optimized zener voltage point near the zero-temperature-coefficient crossover (~5.6 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.67–5.92 V at IZ = 5 mA - defines precise shunt regulation point for feedback or reference use |
| Dynamic Resistance (rd) | ≤ 80 Ω at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Power Dissipation (Pd) | 200 mW at Ta = 25°C - sets maximum continuous power handling before thermal derating |
| Reverse Current (IR) | ≤ 5 μA at VR = 2.5 V - ensures low leakage in standby or high-impedance bias networks |
| Junction Temperature (Tj) | 150°C maximum - constrains thermal design margin for PCB copper area and airflow |
| Temperature Coefficient (γZ) | ~+0.02 mV/°C near 5.6 V - enables stable reference performance across industrial temperature range |
Pinout & Package
Package: MPAK (JEITA code PLSP0003ZC-A), 3-pin surface-mount package with 1.0 mm × 1.3 mm footprint, 0.4 mm nominal lead pitch, and 0.16 mm min lead thickness. Pin 1 is NC (no connection), Pin 2 is Anode, Pin 3 is Cathode - polarity critical for correct shunt operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connection (NC) | Electrically isolated terminal; must not be soldered to trace or plane |
| 2 | Anode | Connected to lower-potential node (e.g., ground or return path) in shunt configuration |
| 3 | Cathode | Connected to regulated voltage node; reverse-biased during normal operation |
Key Features
| Feature | Design Value |
|---|---|
| Grade-B2 zener voltage tolerance | ±2.5% (5.67–5.92 V) - enables tighter system-level voltage accuracy without trimming |
| Low dynamic resistance | ≤ 80 Ω - minimizes output voltage variation under changing load current |
| MPAK surface-mount package | 1.0 mm × 1.3 mm footprint - supports high-density layout and automated assembly |
| Zero-TC crossover optimization | γZ ≈ +0.02 mV/°C at 5.6 V - reduces temperature-induced drift in reference applications |
| Industrial temperature range | –55°C to +150°C storage; 150°C max junction - suitable for extended-environment deployments |
Applications

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 |
|---|---|---|---|
| BZX84-C5V6 (Diodes Inc.) | Same nominal VZ (5.6 V), SOT-23 package, ±5% tolerance (B grade), rd = 40 Ω typical - lower dynamic resistance but wider voltage spread | Higher volume availability and broader distributor stock; less suitable for tight-tolerance feedback loops | Select when cost sensitivity outweighs ±2.5% voltage precision; verify SOT-23 pad layout compatibility |
| MMSZ5232BS (ON Semiconductor) | VZ = 5.6 V ±5%, SOD-123 package, Pd = 500 mW - higher power rating but looser tolerance and larger footprint | Better suited for higher-current clamping; not optimized for low-drift reference use | Choose where thermal margin >200 mW is required and board space allows 2.7 mm × 1.6 mm footprint |
Compared with BZX84-C5V6 and MMSZ5232BS, the HZM5.6NB2JTR offers tighter voltage tolerance and MPAK's compact size for space-constrained reference designs, though it requires careful thermal management due to its 200 mW limit and NC pin layout constraint.

FAQ
What is the exact zener voltage range for HZM5.6NB2JTR at 5 mA test current?
The HZM5.6NB2JTR has a guaranteed zener voltage range of 5.67 V to 5.92 V when tested at IZ = 5 mA and Ta = 25°C. This B2-grade specification reflects ±2.5% tolerance around the nominal 5.6 V point, confirmed in the R07DS0358EJ0600 datasheet Table on page 2. The HZM5.6NB2JTR achieves this tight distribution via process-controlled epitaxial planar junction fabrication.
Does HZM5.6NB2JTR have a usable pin 1, and what happens if it's connected?
No - pin 1 of the HZM5.6NB2JTR is designated NC (No Connection) and must remain unconnected in circuit layout. The datasheet explicitly states "1. NC" in the Pin Arrangement diagram (page 1), and internal construction confirms electrical isolation. Soldering pin 1 to ground or any net may cause unpredictable leakage paths or thermal stress; the HZM5.6NB2JTR will not function correctly if pin 1 is inadvertently tied.
How does the temperature coefficient of HZM5.6NB2JTR compare to other 5.6 V Zener diodes?
The HZM5.6NB2JTR exhibits a temperature coefficient (γZ) of approximately +0.02 mV/°C near its 5.6 V operating point, placing it close to the zero-TC crossover zone shown in Figure 2 (page 5). This is significantly more stable than generic 5.6 V Zeners with γZ > ±2 mV/°C. The HZM5.6NB2JTR leverages Renesas' epitaxial planar process to achieve this low drift, making it preferable for reference applications where <10 ppm/°C stability is required.
Can HZM5.6NB2JTR replace a standard 1N4734A in existing designs?
No - the HZM5.6NB2JTR is not a drop-in replacement for the 1N4734A. While both regulate near 5.6 V, the HZM5.6NB2JTR uses a 3-pin MPAK package with pin 1 (NC), whereas the 1N4734A is a 2-pin DO-41 device. Layout, thermal design, and soldering process differ fundamentally. Additionally, the HZM5.6NB2JTR's 200 mW rating is lower than the 1N4734A's 1 W rating. Redesign is required to use the HZM5.6NB2JTR.
What is the maximum reverse leakage current for HZM5.6NB2JTR at 2.5 V?
The maximum reverse leakage current (IR) for the HZM5.6NB2JTR is 5 μA when measured at VR = 2.5 V and Ta = 25°C, as specified in the Electrical Characteristics table (page 2). This low leakage supports high-impedance bias networks and minimizes error in precision reference paths. The HZM5.6NB2JTR maintains this spec across its full operating temperature range due to its epitaxial planar junction design.
