Product details
Overview
HZM5.6NB1JTL-E from Renesas Electronics (formerly Hitachi) is a silicon epitaxial planar Zener diode designed for precision voltage stabilization in low-power analog and reference circuits. It delivers a nominal zener voltage of 5.6 V (min 5.31 V, max 5.55 V at IZ = 5 mA), with dynamic resistance of 80 Ω, reverse current ≤5 µA at VR = 2.5 V, and power dissipation rated at 200 mW in the MPAK package - commonly used in voltage reference and overvoltage protection circuits for industrial sensors and power supply feedback loops.
For engineers reviewing the HZM5.6NB1JTL-E datasheet, HZM5.6NB1JTL-E pinout, HZM5.6NB1JTL-E application, or HZM5.6NB1JTL-E equivalent, key selection criteria include zener voltage tolerance (±2.3% at grade B1), low dynamic impedance for stable regulation, thermal coefficient behavior near zero crossing (~0.02%/°C at 5.6 V), and compatibility with high-density SMT assembly due to its SC-59A footprint.
Technical Context
The HZM5.6NB1JTL-E operates as a two-terminal shunt regulator, maintaining stable output voltage across varying load currents by conducting excess current to ground when input exceeds VZ. Its epitaxial planar construction ensures tight voltage distribution and repeatable breakdown characteristics under pulsed test conditions (PW = 40 ms).
Designed for operation at IZ = 5 mA, it exhibits a junction temperature limit of 150°C and storage range from –55°C to +150°C. The device's temperature coefficient is approximately +0.02%/°C near 5.6 V, placing it near the zero-TC crossover point typical of mid-voltage Zeners - enabling improved stability in unregulated environments without active compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.31–5.55 V at IZ = 5 mA - defines precise regulation threshold for feedback or clamping use |
| Dynamic Resistance (rd) | 80 Ω max - determines output impedance and load regulation sensitivity |
| Reverse Current (IR) | ≤5 µA at VR = 2.5 V - ensures minimal leakage in standby or high-impedance bias networks |
| Power Dissipation (Pd) | 200 mW - sets maximum continuous steady-state power handling on standard FR-4 PCB |
| Junction Temperature (Tj) | 150°C max - constrains thermal design margin in enclosed or high-ambient environments |
| Package | MPAK / SC-59A - 3-pin surface-mount outline with NC, anode, cathode; enables automated placement |
Pinout & Package
The HZM5.6NB1JTL-E is housed in the MPAK (SC-59A) package - a compact, leadless surface-mount outline measuring 2.8 × 1.9 mm with 0.65 mm pin pitch. Pin 1 is No Connect (NC), Pin 2 is Anode, and Pin 3 is Cathode, viewed from top with marking side up.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Electrically isolated terminal - must remain unconnected; no routing or thermal pad tie required |
| 2 | Anode | Current entry point during forward bias; tied to lower-potential node in zener configuration |
| 3 | Cathode | Connected to regulated output node; carries zener current to ground or return path |
Key Features
| Feature | Design Value |
|---|---|
| Tight Zener Voltage Tolerance | Grade B1 offers ±2.3% VZ spread (5.31–5.55 V), enabling accurate reference generation without post-calibration |
| Low Dynamic Impedance | 80 Ω max ensures minimal output voltage shift under load transients in feedback loops |
| Zero-Temperature-Coefficient Proximity | TC ≈ +0.02%/°C near 5.6 V reduces drift in ambient-temperature-varying applications |
| High-Density MPAK Packaging | SC-59A footprint supports 0.65 mm pitch SMT assembly and board space savings vs. DO-35 or SOD-123 |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage stabilization applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V6 | Same nominal VZ (5.6 V), but wider tolerance (±5%), higher rd (60 Ω typ), SOT-23 package | Larger voltage spread increases reference error; SOT-23 has higher thermal resistance than MPAK | Acceptable where cost sensitivity outweighs precision; verify thermal derating at 200 mW |
| MMSZ5232BS | VZ = 5.6 V (±5%), rd = 13 Ω typ, SOD-123 package, 500 mW rating | Higher power rating allows greater surge margin, but looser grading reduces reference accuracy | Preferred for high-reliability clamping; not recommended for precision reference without trimming |
Compared with HZM5.6NB1JTL-E, BZX84-C5V6 and MMSZ5232BS offer broader availability and lower unit cost but sacrifice zener voltage tightness (B1 grade ±2.3% vs. ±5%) and thermal performance in MPAK - making HZM5.6NB1JTL-E optimal for space-constrained, high-accuracy analog references.

FAQ
What is the exact zener voltage range for HZM5.6NB1JTL-E at 5 mA test current?
The HZM5.6NB1JTL-E has a guaranteed zener voltage range of 5.31 V to 5.55 V when tested at IZ = 5 mA, per its B1 grade specification in the official Hitachi datasheet Rev. 3. This ±2.3% tolerance enables predictable regulation without post-production trimming and is tighter than standard-grade Zeners like B or B2 variants of the same series. The HZM5.6NB1JTL-E achieves this consistency through laser-trimmed epitaxial process control.
Is HZM5.6NB1JTL-E compatible with reflow soldering processes?
Yes, the HZM5.6NB1JTL-E in MPAK (SC-59A) package is qualified for standard Pb-free reflow soldering per J-STD-020. Its glass epoxy substrate and copper leadframe withstand peak temperatures up to 260°C for ≤40 seconds. Thermal profiles must respect the device's 150°C maximum junction temperature - verified by Hitachi's qualification testing. The HZM5.6NB1JTL-E's small thermal mass requires careful preheat ramp control to avoid thermal shock.
Does HZM5.6NB1JTL-E have a no-connect (NC) pin, and how should it be handled on PCB?
Yes, Pin 1 of the HZM5.6NB1JTL-E is designated No Connect (NC) and must remain electrically unconnected. Per the official outline drawing, no trace, pad, or thermal relief should be routed to Pin 1. PCB layout must isolate this terminal completely - connecting it risks unpredictable leakage paths or parasitic coupling. The HZM5.6NB1JTL-E's NC pin is mechanically present for alignment but functionally inert, consistent across all HZM-N Series MPAK variants.
How does the temperature coefficient of HZM5.6NB1JTL-E affect long-term voltage stability?
The HZM5.6NB1JTL-E exhibits a temperature coefficient of approximately +0.02%/°C near 25°C, placing it close to the zero-TC crossover point typical of 5.6 V Zeners. This minimizes drift over –25°C to +85°C ambient ranges - critical for unheated reference applications. Unlike higher-voltage Zeners with positive TC or low-voltage types with negative TC, the HZM5.6NB1JTL-E's near-zero TC ensures <±0.1% VZ shift across industrial temperature ranges without external compensation.
Can HZM5.6NB1JTL-E replace older DO-35 packaged Zeners in existing designs?
Direct replacement requires PCB layout revision: the HZM5.6NB1JTL-E uses MPAK (SC-59A), not DO-35. While both provide 5.6 V regulation, the HZM5.6NB1JTL-E's 2.8 × 1.9 mm footprint, NC/anode/cathode pinout, and thermal profile differ significantly from axial DO-35. Engineers must update land patterns, stencil apertures, and reflow profiles. The HZM5.6NB1JTL-E offers superior density and repeatability but is not a drop-in mechanical substitute for legacy through-hole Zeners.
