Product details
Overview
HZM5.1NB1JTL-E 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 5.14–5.55 V at 5 mA, dynamic resistance ≤130 Ω, power dissipation rating 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 HZM5.1NB1JTL-E datasheet, HZM5.1NB1JTL-E pinout, HZM5.1NB1JTL-E application, or HZM5.1NB1JTL-E equivalent, key selection criteria include zener voltage tolerance (±4.3% at 5 mA), low temperature coefficient (≈+0.025 mV/°C near 5.1 V), junction temperature limit (150°C), and compatibility with high-density automated assembly due to its MPAK footprint.
Technical Context
The HZM5.1NB1JTL-E 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 silicon epitaxial planar construction ensures tight voltage distribution and repeatable dynamic resistance behavior.
It exhibits a positive temperature coefficient near 5.1 V (≈+0.025 mV/°C), enabling predictable drift compensation in reference designs. The device is rated for continuous operation up to 150°C junction temperature and supports pulse testing per PW = 40 ms, aligning with standard reliability screening for industrial-grade discrete regulators.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.14–5.55 V at IZ = 5 mA - defines stable regulation range for 5 V-class reference circuits |
| Dynamic Resistance (rd) | ≤130 Ω at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Power Dissipation (Pd) | 200 mW at Ta = 25°C - sets maximum continuous DC power handling before thermal derating |
| Junction Temperature (Tj) | 150°C maximum - defines upper thermal operating limit for PCB layout and ambient design |
| Reverse Current (IR) | ≤5 μA at VR = 1.5 V - specifies leakage level below breakdown, critical for low-power standby circuits |
| Package | MPAK (JEITA PLSP0003ZC-A) - 3-pin SMT package with NC, anode, cathode; 2.7 × 1.35 mm footprint |
| Temperature Coefficient (γZ) | ≈+0.025 mV/°C near 5.1 V - enables predictable voltage drift modeling over –25°C to +85°C ambient |
Pinout & Package
MPAK package (JEITA code PLSP0003ZC-A) is a 3-pin surface-mount plastic package with 1.0 mm height, 2.7 mm length, and 1.35 mm width. Pin 1 is NC (no internal connection), Pin 2 is Anode, Pin 3 is Cathode - top-view orientation matches standard SC-59A-compatible placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connection (NC) | Electrically isolated terminal; must remain unconnected on PCB to avoid parasitic coupling or mechanical stress |
| 2 | Anode | Connected to lower-potential node in shunt configuration; current flows into this terminal during regulation |
| 3 | Cathode | Connected to higher-potential node (e.g., supply rail); zener voltage develops between Cathode and Anode |
Key Features
| Feature | Design Value |
|---|---|
| Zener voltage grade B1 | 5.14–5.55 V tolerance band ensures tighter regulation than grade B (±5%) or B2/B3 for precision references |
| MPAK surface-mount package | Enables high-density PCB layouts and compatibility with standard 0805–1206 pick-and-place equipment without rework |
| Low dynamic resistance | ≤130 Ω minimizes output voltage variation under changing load current, improving reference stability in feedback paths |
| 150°C junction rating | Supports operation in thermally constrained environments such as enclosed industrial controllers or automotive under-hood modules |
| Pulse-tested characterization | Electrical specs validated using 40 ms pulses, confirming performance consistency under transient thermal conditions |

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-C5V1LT1G | 5.1 V nominal (±5%), SOT-23 package, 350 mW Pd, rd ≈ 60 Ω - higher power but looser tolerance and different footprint | Preferred where higher surge capability or legacy SOT-23 layout reuse is required; not drop-in due to pinout and size mismatch | Select when board space allows larger SOT-23 and ±5% VZ is acceptable; verify thermal relief for 350 mW derating |
| MMSZ5231B-TP | 5.1 V nominal (±5%), SOD-123 package, 500 mW Pd, rd ≈ 17 Ω - higher power, lower rd, but wider VZ tolerance and no NC pin | Suitable for cost-sensitive consumer power rails; lacks NC pin, limiting noise-isolation options in sensitive analog designs | Choose for high-volume, non-critical 5 V clamping; avoid where NC pin isolation or B1-grade tolerance is mandatory |
Compared with HZM5.1NB1JTL-E, BZX84-C5V1LT1G offers higher power but sacrifices voltage precision and MPAK compatibility, while MMSZ5231B-TP delivers lower impedance at the cost of tolerance control and terminal isolation - making HZM5.1NB1JTL-E optimal for compact, precision-stable shunt references.

FAQ
What is the exact zener voltage range specified for HZM5.1NB1JTL-E at 5 mA test current?
The HZM5.1NB1JTL-E has a guaranteed zener voltage range of 5.14 V to 5.55 V when tested at IZ = 5 mA, corresponding to Grade B1 tolerance per the Renesas preliminary datasheet R07DS0358EJ0600. This 4.3% total spread reflects tighter control than Grade B (±5%) and supports precision reference designs where tighter regulation is required without trimming.
Does HZM5.1NB1JTL-E have a functional NC pin, and how should it be handled on the PCB?
Yes, Pin 1 of the HZM5.1NB1JTL-E is a true No-Connection (NC) terminal with no internal bond wire or die connection. It must remain unconnected on the PCB - neither routed nor soldered - to prevent mechanical stress on the package or unintended capacitive coupling that could affect noise-sensitive reference nodes. The NC pin is part of the MPAK mechanical structure only.
What is the maximum allowable reverse current for HZM5.1NB1JTL-E below its zener knee voltage?
The HZM5.1NB1JTL-E specifies a maximum reverse current (IR) of 5 μA when measured at VR = 1.5 V, per the Electrical Characteristics table. This low leakage supports ultra-low-power applications such as battery-backed sensor biasing or sleep-mode reference retention, where sub-microamp standby current is critical to system runtime.
How does the temperature coefficient of HZM5.1NB1JTL-E compare to other 5 V Zener diodes, and what is its practical impact?
HZM5.1NB1JTL-E exhibits a positive temperature coefficient of approximately +0.025 mV/°C near its 5.1 V operating point, as shown in Figure 2 of the datasheet. This is significantly lower in magnitude than typical 5.1 V Zeners (often ±2–5 mV/°C), enabling improved thermal stability in reference circuits - especially when paired with components exhibiting complementary negative drift, such as certain op-amps or resistors.
Is HZM5.1NB1JTL-E suitable for automotive under-hood applications, and what thermal limits apply?
HZM5.1NB1JTL-E is rated for junction temperatures up to 150°C and storage from –55°C to +150°C, meeting requirements for non-safety-critical automotive cabin and engine-compartment-adjacent applications (e.g., HVAC controls, body ECUs). However, it carries Renesas' "Standard" quality grade - not "High Quality" - so it is not qualified for ASIL-B/C safety functions or direct engine-control use without additional validation by the end customer.
