Product details
Overview
HZM5.1NB2JTR-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 5.14–5.37 V at 5 mA, dynamic resistance of ≤130 Ω, power dissipation rating of 200 mW, and MPAK surface-mount package optimized for high-density PCB layouts.
For engineers reviewing the HZM5.1NB2JTR-E datasheet, HZM5.1NB2JTR-E pinout, HZM5.1NB2JTR-E application, or HZM5.1NB2JTR-E equivalent, key selection considerations include its B2-grade voltage tolerance (±2.3% typical), low temperature coefficient (≈+0.025 mV/°C near 5.1 V), NC terminal isolation, and suitability for voltage reference, overvoltage clamping, and biasing in industrial sensor interfaces and portable power management.
Technical Context
The HZM5.1NB2JTR-E operates as a two-terminal shunt regulator with an NC (no-connect) terminal that electrically isolates the die substrate to minimize parasitic capacitance and leakage-critical for stable reference performance in noise-sensitive analog front-ends. Its epitaxial planar construction ensures tight voltage distribution and repeatable breakdown characteristics across temperature.
Designed for DC stabilization rather than transient suppression, it specifies reverse current ≤5 µA at VR = 1.5 V and exhibits a positive temperature coefficient near 5.1 V (≈+0.025 mV/°C), enabling predictable drift compensation in multi-device reference networks. It is not rated for surge or ESD protection applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.14–5.37 V at IZ = 5 mA - defines stable regulation point for low-current references |
| 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 before thermal derating |
| Reverse Current (IR) | ≤5 µA at VR = 1.5 V - ensures minimal leakage in standby or high-impedance bias networks |
| Junction Temperature (Tj) | 150°C maximum - defines upper thermal limit for reliable long-term operation |
| Temperature Coefficient (γZ) | ≈+0.025 mV/°C near 5.1 V - enables predictable, low-drift behavior in ambient temperature variations |
| Package | MPAK (JEITA PLSP0003ZC-A) - 3-pin SMT package with 1.0 mm × 1.3 mm footprint and 0.55 mm height |
Pinout & Package
MPAK package (PLSP0003ZC-A) features a compact 3-terminal surface-mount outline with exposed pad thermal path; pin 1 is NC (no internal connection), pin 2 is anode, pin 3 is cathode - orientation confirmed by top-view marking diagram and mechanical drawings on page 6 of R07DS0358EJ0600.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No Connect (NC) | Electrically isolated substrate terminal; must remain unconnected to avoid parasitic coupling or thermal stress |
| 2 | Anode | DC input terminal; connects to lower-potential node in shunt regulation configuration |
| 3 | Cathode | Regulated output terminal; connects to reference node and current-limiting resistor |
Key Features

| NC terminal isolation | Substrate decoupling reduces capacitive feedthrough and leakage in high-impedance feedback paths |
| Low dynamic resistance | ≤130 Ω at 5 mA - minimizes output voltage shift under varying load current |
| MPAK surface-mount package | 1.0 mm × 1.3 mm footprint with 0.55 mm profile - supports high-density layout and automated assembly |
| Positive temperature coefficient | +0.025 mV/°C near 5.1 V - allows predictable drift modeling and compensation in multi-Zener networks |

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-C5V1LT1G | 5.1 V ±5%, SOT-23, rd = 60 Ω, Pd = 300 mW, no NC pin | Higher power rating but lacks NC terminal; higher leakage (IR ≤ 10 µA @ 2 V) | Preferred where board space permits SOT-23 and substrate isolation is non-critical |
| MMSZ5231B-TP | 5.1 V ±5%, SOD-123, rd = 17 Ω, Pd = 500 mW, no NC pin | Lower rd and higher Pd, but no NC terminal and wider voltage tolerance | Chosen when ultra-low impedance is prioritized over voltage precision and noise isolation |
Compared with BZX84-C5V1LT1G and MMSZ5231B-TP, the HZM5.1NB2JTR-E trades higher power capability and lower dynamic resistance for superior voltage tolerance (±2.3% vs. ±5%) and substrate isolation via the NC pin-making it optimal for precision, low-noise reference designs where layout density and thermal profile constrain alternative packages.

FAQ
What is the exact zener voltage range for HZM5.1NB2JTR-E at 5 mA?
The HZM5.1NB2JTR-E has a guaranteed zener voltage range of 5.14 V to 5.37 V when tested at IZ = 5 mA and Ta = 25°C, corresponding to its B2 grade per R07DS0358EJ0600 Rev.6.00. This ±2.3% tolerance is tighter than standard ±5% Zeners and supports high-accuracy reference designs without trimming. The HZM5.1NB2JTR-E achieves this via epitaxial planar process control and binning.
Why does HZM5.1NB2JTR-E have a no-connect (NC) pin?
Pin 1 of the HZM5.1NB2JTR-E is designated NC to electrically isolate the silicon substrate from PCB traces, reducing parasitic capacitance and leakage current that could degrade reference stability in high-impedance analog circuits. This feature is confirmed in the "Pin Arrangement" diagram on page 1 and mechanical drawings on page 6 of the datasheet. The HZM5.1NB2JTR-E must be mounted with pin 1 unconnected.
What is the maximum allowable power dissipation for HZM5.1NB2JTR-E at 70°C ambient?
Per Figure 3 in R07DS0358EJ0600, the HZM5.1NB2JTR-E's power dissipation derates linearly from 200 mW at 25°C to approximately 140 mW at 70°C ambient temperature. This is calculated using the specified thermal resistance and ambient derating curve; exceeding this limit risks junction temperature exceeding 150°C. The HZM5.1NB2JTR-E must be used within this derated envelope for reliable operation.
Is HZM5.1NB2JTR-E suitable for ESD or transient voltage suppression?
No - the HZM5.1NB2JTR-E is not characterized or rated for ESD or transient suppression. Its absolute maximum ratings specify only DC conditions (Pd = 200 mW, Tj = 150°C), and its electrical characteristics are defined for steady-state zener operation. For transient protection, dedicated TVS diodes such as the PESD5V0S1BA should be used instead. The HZM5.1NB2JTR-E serves strictly as a precision DC voltage reference.
What is the temperature coefficient of HZM5.1NB2JTR-E near its nominal voltage?
The HZM5.1NB2JTR-E exhibits a positive temperature coefficient of approximately +0.025 mV/°C near 5.1 V, as shown in Figure 2 ("Temperature Coefficient vs. Zener Voltage") of R07DS0358EJ0600. This low, predictable drift enables stable reference performance across –25°C to +85°C operating ranges. The HZM5.1NB2JTR-E's coefficient is significantly lower than that of lower-voltage Zeners (<3 V) and avoids the negative drift seen in >6 V devices.
