Product details
Overview
P6SMB120AHE3_A/H from Vishay General Semiconductor is a unidirectional 120 V standoff transient voltage suppressor (TVS) diode in SMB (DO-214AA) package, rated for 600 W peak pulse power (10/1000 μs), 165 V maximum clamping voltage at 3.6 A peak pulse current, and 100 °C/W junction-to-ambient thermal resistance - deployed to protect MOSFETs and sensor signal lines in automotive power electronics against inductive switching transients.
For engineers reviewing the P6SMB120AHE3_A/H datasheet, P6SMB120AHE3_A/H pinout, P6SMB120AHE3_A/H application, or P6SMB120AHE3_A/H equivalent, key selection criteria include verified unidirectional polarity, AEC-Q101 qualification status, 120 V stand-off voltage tolerance (±5%), clamping performance under 10/1000 μs surge, and RoHS-compliant matte tin terminations meeting J-STD-002 solderability standards.
Technical Context
The P6SMB120AHE3_A/H operates as a silicon avalanche diode with glass-passivated junction, delivering fast response time (<1 ns) and low incremental surge resistance to clamp transient overvoltages before downstream ICs or MOSFETs are damaged. Its unidirectional configuration enables integration into DC-biased power rails where reverse conduction must be blocked.
Designed for surface-mount automated placement on PCBs with 0.2" × 0.2" copper pads per terminal, it meets MSL Level 1 per J-STD-020 and supports peak forward surge current of 100 A (8.3 ms half-sine), with operating junction temperature range from –65 °C to +150 °C and thermal resistance RθJA = 100 °C/W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VWM) | 102 V - Maximum continuous reverse working voltage before breakdown; defines safe DC operating margin for 12 V–48 V systems. |
| Breakdown Voltage (VBR) | 114–126 V at 1 mA - Confirmed avalanche initiation range; ensures predictable turn-on during transients without premature conduction. |
| Clamping Voltage (VC) | 165 V at 3.6 A (10/1000 μs) - Measured peak voltage across device during standardized surge; determines maximum stress on protected circuitry. |
| Peak Pulse Power (PPPM) | 600 W - Sustained energy absorption capability under repetitive 0.01% duty cycle surges; validates robustness in automotive load-dump scenarios. |
| Leakage Current (ID) | 1 μA max at 102 V - Ultra-low reverse leakage preserves efficiency in high-impedance bias networks and battery-powered sensors. |
| Junction Temperature Range | –65 °C to +150 °C - Enables deployment in under-hood automotive environments and industrial motor control enclosures. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002; cathode indicated by band at one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias | Connected to system ground or low-side return path; enables unidirectional clamping from rail to GND. |
| Cathode | Current exit terminal in forward bias; marked with band | Connected to protected line (e.g., 12 V supply or sensor output); conducts surge current to ground when VIN exceeds VWM. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - required for engine control, ADAS, and body electronics. |
| Glass passivated junction | Enhances long-term stability and moisture resistance versus epoxy-passivated alternatives, critical for 15+ year automotive service life. |
| 600 W peak pulse rating (10/1000 μs) | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-earth) in properly designed PCB layouts with recommended 5.0 mm × 5.0 mm copper pads. |
| MSL Level 1 (260 °C peak reflow) | Enables single-pass lead-free reflow assembly without popcorn cracking or delamination - eliminates post-reflow inspection overhead. |
| RoHS-compliant & halogen-free option available | Meets EU ELV and China RoHS requirements; HE3 suffix confirms compliance without compromising electrical performance or thermal derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ120A-E3/52 | Same 120 V VWM, but 400 W PPPM; SMA package (smaller footprint, higher RθJA = 140 °C/W). | Limited to lower-energy transients; unsuitable for ISO 7637-2 Pulse 5a without parallel staging. | Select when board space is constrained and surge energy does not exceed 40 mJ (10/1000 μs). |
| 1.5SMC120A | Same 120 V VWM, 600 W rating, but SMC package (larger, RθJA = 60 °C/W); non-AEC-Q101. | Higher thermal margin for sustained surge repetition, but lacks automotive qualification documentation. | Prefer for industrial UPS or solar charge controllers where AEC-Q101 is not mandated and thermal headroom is critical. |
Compared with SMAJ120A-E3/52 and 1.5SMC120A, the P6SMB120AHE3_A/H delivers identical clamping performance in a compact SMB footprint while providing certified AEC-Q101 reliability and optimized thermal resistance for automotive under-hood use - making it the only choice when both space constraints and automotive qualification are mandatory.

FAQ
What is the exact standoff voltage range for P6SMB120AHE3_A/H?
The P6SMB120AHE3_A/H has a specified stand-off voltage (VWM) of 102 V, derived from the 120 V nominal rating with a ±5% tolerance per the P6SMB series standard. This value is confirmed in the Electrical Characteristics table on page 2 of Vishay document 88370, where P6SMB120A shows VWM = 102 V at ID ≤ 1 μA. The P6SMB120AHE3_A/H inherits this parameter directly as a variant of the base P6SMB120A part.
Is P6SMB120AHE3_A/H AEC-Q101 qualified?
Yes, P6SMB120AHE3_A/H is AEC-Q101 qualified. The "HE3" suffix explicitly denotes RoHS-compliant and AEC-Q101 qualified construction, as stated in the Mechanical Data section of document 88370: "Base P/NHE3_X - RoHS-compliant and AEC-Q101 qualified". The "_A/H" ordering code further confirms tape-and-reel packaging compliant with automotive logistics requirements.
What is the maximum clamping voltage of P6SMB120AHE3_A/H at rated surge current?
The P6SMB120AHE3_A/H has a maximum clamping voltage (VC) of 165 V at 3.6 A peak pulse current under the standard 10/1000 μs waveform. This value is published in the Electrical Characteristics table for P6SMB120A on page 2 of document 88370 and applies identically to the P6SMB120AHE3_A/H variant, which shares the same core die and electrical specifications.
Does P6SMB120AHE3_A/H have bidirectional capability?
No, P6SMB120AHE3_A/H is a unidirectional TVS diode. Its part number ends in "A", not "CA", and the datasheet specifies polarity as "Unidirectional, bidirectional" only at the series level - individual part numbers like P6SMB120A are unidirectional. The cathode band marking and absence of symmetrical VBR min/max values confirm this configuration.
What is the thermal resistance junction-to-ambient for P6SMB120AHE3_A/H?
The P6SMB120AHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W, measured under standard conditions with 0.2" × 0.2" copper pads per terminal. This value is listed in the Thermal Characteristics table on page 3 of Vishay document 88370 and applies to all P6SMB variants in SMB (DO-214AA) package, including P6SMB120AHE3_A/H.
