Product details
Overview
P6SMB180CAHE3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the P6SMB series, designed for clamping voltage transients on signal or power lines. It features a 154 V stand-off voltage (VWM), 171–189 V breakdown voltage (VBR) at 1 mA test current, 246 V maximum clamping voltage (VC) at 2.4 A peak pulse current (IPPM), and 600 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in industrial and automotive electronics.
For engineers reviewing the P6SMB180CAHE3/52 datasheet, P6SMB180CAHE3/52 pinout, P6SMB180CAHE3/52 application, or P6SMB180CAHE3/52 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, SMB (DO-214AA) package compatibility, and thermal resistance (RθJA = 100 °C/W) for board-level surge protection design.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling suppression of positive and negative transients without polarity sensitivity. Its glass-passivated junction ensures stable breakdown behavior and low leakage (<1.0 μA at VWM), while the low incremental surge resistance supports fast response to ESD and lightning-induced surges.
The device is rated for repetitive 10/1000 μs pulses at 0.01 % duty cycle and derates linearly above 25 °C ambient per Fig. 2. With a maximum junction temperature of +150 °C and MSL Level 1 moisture sensitivity, it supports lead-free reflow up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 154 V - Maximum continuous reverse voltage before clamping begins; defines safe operating window for protected circuitry. |
| VBR (Breakdown) | 171–189 V at 1 mA - Confirmed voltage range where device transitions from high-impedance to low-impedance clamping state. |
| VC (Clamping) | 246 V at IPPM = 2.4 A - Peak voltage seen by downstream components during worst-case transient; critical for IC voltage margining. |
| PPPM | 600 W - Peak pulse power handling with 10/1000 μs waveform; determines survivability against IEC 61000-4-5 surge events. |
| RθJA | 100 °C/W - Junction-to-ambient thermal resistance on standard 0.2" × 0.2" copper pads; guides PCB copper area requirements for thermal management. |

FAQ
What is the clamping voltage of P6SMB180CAHE3/52 at its rated peak pulse current?
The P6SMB180CAHE3/52 has a maximum clamping voltage (VC) of 246 V at its specified peak pulse current (IPPM) of 2.4 A with a 10/1000 μs waveform. This value is measured under standardized test conditions per JEDEC standards and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is P6SMB180CAHE3/52 suitable for automotive applications?
Yes, P6SMB180CAHE3/52 is AEC-Q101 qualified, confirming its reliability for automotive use cases including engine control units, body electronics, and ADAS sensor interfaces. The HE3 suffix explicitly denotes RoHS-compliant and AEC-Q101-qualified construction, validated for temperature cycling, high-temperature reverse bias, and mechanical shock per automotive stress test protocols.
What does the "CA" suffix indicate in P6SMB180CAHE3/52?
The "CA" suffix in P6SMB180CAHE3/52 denotes a bidirectional configuration - meaning the device provides symmetrical transient suppression for both positive and negative voltage excursions. Unlike unidirectional variants (e.g., P6SMB180A), this part has no polarity marking and functions identically regardless of voltage polarity applied across its terminals.
What is the thermal resistance of P6SMB180CAHE3/52, and how does it affect PCB layout?
P6SMB180CAHE3/52 has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes minimal copper area; increasing pad size or adding thermal vias lowers RθJA, improving surge repetition capability and steady-state power dissipation margin in high-duty-cycle applications.
How does P6SMB180CAHE3/52 differ from P6SMB180AHE3/52?
P6SMB180CAHE3/52 is bidirectional with symmetrical clamping behavior and no polarity marking, whereas P6SMB180AHE3/52 is unidirectional - featuring a cathode band and conducting only in reverse bias. Their VWM (154 V), VBR (171–189 V), and VC (246 V) are identical, but the unidirectional version blocks forward current and requires correct orientation during placement.
