Product details
Overview
HZM9.1NB1JTL-E from Renesas Electronics 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 9.1 V (min 9.45 V, max 9.87 V at IZ = 5 mA), with dynamic resistance of 30 Ω, reverse current ≤2 μA at VR = 6.0 V, and power dissipation up to 200 mW in the MPAK surface-mount package - commonly used in voltage reference rails for sensor signal conditioning.
For engineers reviewing the HZM9.1NB1JTL-E datasheet, HZM9.1NB1JTL-E pinout, HZM9.1NB1JTL-E application, or HZM9.1NB1JTL-E equivalent, key selection criteria include zener voltage tolerance (±4.1% at 25°C), temperature coefficient (≈+0.035 mV/°C), thermal derating behavior above 25°C, and compatibility with high-density SMT assembly lines requiring PLSP0003ZC-A footprint compliance.
Technical Context
The HZM9.1NB1JTL-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 silicon epitaxial planar construction ensures tight voltage distribution and low noise performance suitable for precision biasing.
It is rated for junction temperatures up to 150°C and storage from –55°C to +150°C, with absolute maximum power dissipation of 200 mW at Ta = 25°C - derating linearly to zero at ~150°C per Fig.3. The device exhibits a positive temperature coefficient (~+0.035 mV/°C) typical of mid-voltage Zeners (7–10 V range), minimizing drift in ambient-temperature-varying applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.45 V min / 9.87 V max at IZ = 5 mA - defines stable regulation window for reference design |
| Dynamic Resistance (rd) | 30 Ω max at IZ = 5 mA - determines output impedance and load regulation sensitivity |
| Reverse Current (IR) | ≤2 μA at VR = 6.0 V - ensures minimal leakage in standby or low-current bias networks |
| Power Dissipation (Pd) | 200 mW at Ta = 25°C - sets maximum continuous power handling before thermal shutdown risk |
| Junction Temperature (Tj) | 150°C max - constrains PCB layout for thermal relief and copper pour requirements |

|---|---|
Use Scenario: Stabilizing excitation voltage for resistive bridge sensors (e.g., strain gauges, RTDs) in factory-floor transmitters. IC Role / Device Role / Timing Role: Shunt voltage reference providing fixed 9.1 V bias to bridge circuitry, rejecting supply ripple and load variation. Use Value: Enables <±0.1% full-scale accuracy over 0–70°C due to low rd and predictable γZ, reducing need for digital calibration. |

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-C9V1LT1G (ON Semiconductor) | Same VZ grade (9.1 V, ±5%), SOT-23 package, rd = 60 Ω, Pd = 300 mW | Higher power rating but larger footprint; less suitable for ultra-dense layouts | Preferred where higher surge tolerance is needed and board space permits SOT-23 |
| MMSZ5240B-TP (Micro Commercial Components) | VZ = 10 V (±5%), SOD-123 package, rd = 17 Ω, Pd = 500 mW | 10 V nominal vs. 9.1 V; requires circuit recalibration; higher power margin | Used when 10 V reference is acceptable and higher thermal robustness is prioritized |
Compared with BZX84-C9V1LT1G and MMSZ5240B-TP, the HZM9.1NB1JTL-E offers tighter voltage tolerance (±4.1% vs. ±5%), smaller MPAK footprint (1.0 × 1.3 mm vs. SOT-23's 2.9 × 1.3 mm), and optimized rd for low-current reference use - making it preferable for space-constrained, high-accuracy analog subsystems.

FAQ
What is the exact zener voltage range for HZM9.1NB1JTL-E at 5 mA test current?
The HZM9.1NB1JTL-E has a guaranteed zener voltage range of 9.45 V minimum to 9.87 V maximum when tested at IZ = 5 mA and Ta = 25°C. This B1-grade tolerance corresponds to ±4.1% around the nominal 9.1 V rating, as specified in the R07DS0358EJ0600 Rev.6.00 datasheet, page 3.
Does HZM9.1NB1JTL-E have a functional third pin, and how should Pin 1 be handled on the PCB?
No - Pin 1 of the HZM9.1NB1JTL-E is explicitly designated "NC" (No Connect) in the datasheet pin arrangement diagram and must remain unconnected on the PCB. Only Pins 2 (Anode) and 3 (Cathode) are electrically active; connecting Pin 1 risks mechanical stress or unintended coupling, violating the device's MPAK package specification (PLSP0003ZC-A).
What is the maximum allowable reverse voltage before significant leakage occurs in HZM9.1NB1JTL-E?
Per the Electrical Characteristics table, HZM9.1NB1JTL-E guarantees reverse current ≤2 μA when reverse voltage (VR) is held at 6.0 V. Exceeding this voltage increases leakage exponentially; operation above 6.0 V should be avoided unless transient clamping is intended and power dissipation remains within 200 mW limits.
Can HZM9.1NB1JTL-E be used in place of a 9.1 V Zener with different grading (e.g., B2 or B3)?
Only if the application tolerates wider voltage spread: HZM9.1NB1JTL-E (B1 grade) has tighter bounds (9.45–9.87 V) than B2 (9.77–10.21 V) or B3 (9.15–9.55 V). Substituting grades alters regulation accuracy and may require recalibration; B1 is not interchangeable with B2/B3 without verifying system-level voltage margin.
How does ambient temperature affect the power dissipation capability of HZM9.1NB1JTL-E?
HZM9.1NB1JTL-E's 200 mW power rating applies only at Ta = 25°C. Above that, dissipation must be linearly derated - reaching zero at approximately 150°C - as shown in Fig.3 of the datasheet. For example, at 75°C ambient, maximum safe Pd drops to ~150 mW, requiring appropriate PCB copper area and airflow planning.
