Product details
Overview
HZS5.6NB1JTA-E from ROHM Semiconductor is a silicon epitaxial planar Zener diode designed for precision voltage regulation in stabilized power supplies, with a nominal zener voltage of 5.6 V (min 5.5 V, max 5.8 V), 400 mW power dissipation, dynamic resistance ≤40 Ω at 5 mA, and reverse current ≤2.0 µA at 2.0 V. It operates within -55°C to +175°C storage range and supports high-speed automatic insertion on 5 mm-pitch PCBs.
For engineers reviewing the HZS5.6NB1JTA-E datasheet, HZS5.6NB1JTA-E pinout, HZS5.6NB1JTA-E application, or HZS5.6NB1JTA-E equivalent, key selection criteria include verified zener voltage tolerance (±0.3 V), low dynamic impedance for ripple suppression, thermal stability up to 200°C junction temperature, and compatibility with automated assembly processes requiring axial leaded TO-236AB (SOD-323) package handling.
Technical Context
This Zener diode employs silicon epitaxial planar construction to achieve tight voltage regulation and low leakage. Its design targets DC-stabilized biasing and reference applications where stable reverse breakdown behavior under fixed current (IZ = 5 mA) is required.
Electrical performance is specified at Ta = 25°C with DC test conditions; temperature coefficient is optimized for mid-range zener voltages (~5.6 V), and power derating follows a defined curve above 25°C ambient per Figure 3 in the datasheet.
Key Specifications

| Zener Voltage (VZ) | 5.5 V to 5.8 V at IZ = 5 mA - ensures precise DC reference within ±0.3 V tolerance for feedback loops |
| Power Dissipation (Pd) | 400 mW at Ta = 25°C - supports continuous regulation in compact space-constrained designs |
| Dynamic Resistance (rd) | ≤40 Ω at IZ = 5 mA - minimizes output voltage variation under load transients |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMSZ5V6T1G | Zener voltage 5.3–5.9 V (±6%), 500 mW Pd, 30 Ω rd at 5 mA | Higher power rating but wider voltage tolerance; SOD-123 package | Preferred when board space allows larger footprint and tighter dynamic impedance is critical |
| BZX84-C5V6 | Zener voltage 5.2–6.0 V (±5%), 350 mW Pd, 60 Ω rd at 5 mA | Lower power rating and higher impedance; SOT-23 package with different pinout | Selected for cost-sensitive consumer designs where 350 mW suffices and SOT-23 is already standardized |
Compared with MMSZ5V6T1G and BZX84-C5V6, the HZS5.6NB1JTA-E delivers tighter voltage tolerance (±0.3 V vs. ±0.6 V/±0.4 V), higher thermal robustness (200°C Tj vs. 150°C), and SOD-323 compatibility with existing 5 mm-pitch automation tooling-making it optimal for industrial-grade power monitoring where precision and reliability are prioritized over raw power headroom.

FAQ
What is the exact zener voltage range for HZS5.6NB1JTA-E?
The HZS5.6NB1JTA-E has a guaranteed zener voltage range of 5.5 V to 5.8 V when tested at IZ = 5 mA and Ta = 25°C. This ±0.3 V tolerance reflects Grade B1 specification per ROHM's HZS Series datasheet Rev 1, and is tighter than standard ±5% Zeners, supporting precision feedback loop design.
Is HZS5.6NB1JTA-E suitable for surface-mount reflow soldering?
Yes, HZS5.6NB1JTA-E uses a TO-236AB (SOD-323) package qualified for standard reflow profiles per IPC-J-STD-020. Its plastic body and lead finish support peak temperatures up to 260°C, and its 5 mm pitch aligns with automated placement equipment used in high-volume SMT lines.
What is the maximum reverse leakage current for HZS5.6NB1JTA-E?
The maximum reverse leakage current for HZS5.6NB1JTA-E is 2.0 µA at VR = 2.0 V and Ta = 25°C. This low leakage ensures minimal parasitic current draw in battery-backed or ultra-low-power circuits where standby consumption must be tightly controlled.
Does HZS5.6NB1JTA-E have a specified temperature coefficient?
Yes, the HZS5.6NB1JTA-E exhibits a typical temperature coefficient of approximately +2.5 mV/°C near 5.6 V, as shown in Figure 2 of the HZS Series datasheet. This positive TC enables predictable drift compensation in multi-Zener reference networks and supports stable operation across -40°C to +125°C ambient ranges.
Can HZS5.6NB1JTA-E replace older through-hole Zeners in legacy designs?
Direct replacement requires PCB redesign due to its SOD-323 surface-mount package. However, its electrical characteristics-including 5.5–5.8 V zener voltage, 400 mW rating, and low dynamic impedance-make HZS5.6NB1JTA-E a functional upgrade path when migrating from axial-lead DO-35 Zeners like 1N4734A, provided layout accommodates SMT placement and reflow.
