Product details
Overview
P6SMB82CA-E3/52 from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, designed for clamping voltage transients on signal or power lines. It features a 70.1 V standoff voltage (VWM), 77.9–86.1 V breakdown voltage (VBR) at 1 mA, 113 V maximum clamping voltage (VC) at 5.3 A peak pulse current, and 600 W peak pulse power rating with a 10/1000 µs waveform - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the P6SMB82CA-E3/52 datasheet, P6SMB82CA-E3/52 pinout, P6SMB82CA-E3/52 application, or P6SMB82CA-E3/52 equivalent, this page delivers verified electrical parameters, bidirectional clamping behavior, SMB package thermal and mechanical data, and AEC-Q101-qualified alternatives for automotive-grade transient suppression design validation.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, delivering identical clamping performance in forward and reverse directions. Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1.0 µA at VWM), while the low incremental surge resistance enables fast response to ESD and lightning-induced surges.
The device is rated for 150 °C maximum junction temperature and exhibits a typical thermal resistance of 100 °C/W (junction-to-ambient) on standard 0.2" × 0.2" copper pads. Its MSL Level 1 rating supports lead-free reflow up to 260 °C peak, and RoHS-compliant matte tin plating meets J-STD-002 solderability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 70.1 V - Maximum continuous reverse voltage before significant conduction begins; defines safe operating margin below clamping threshold. |
| VBR (Breakdown) | 77.9–86.1 V at 1 mA - Voltage at which device enters avalanche conduction; tight 10.5% tolerance ensures predictable turn-on. |
| VC (Clamping) | 113 V at 5.3 A (10/1000 µs) - Peak voltage seen by protected circuit during worst-case transient; limits stress on downstream ICs. |
| PPPM | 600 W - Peak pulse power handling capability under standardized surge waveform; validates robustness against IEC 61000-4-5 Level 3/4 events. |
| IPPM | 5.3 A - Peak pulse current corresponding to VC; used to size PCB trace width and verify layout survivability. |
| TJ max. | 150 °C - Maximum junction temperature; determines derating curve above 25 °C ambient for sustained reliability. |
| Package | SMB (DO-214AA) - Low-profile surface-mount outline with 5.59 mm × 4.06 mm footprint; optimized for automated placement and thermal dissipation on 0.2" × 0.2" copper pads. |
Pinout & Package
Package: SMB (DO-214AA), bidirectional configuration - no polarity marking; symmetrical terminals function as anode and cathode depending on applied voltage polarity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Terminal 1 | Anode/Cathode (bidirectional) | Either terminal conducts when voltage exceeds ±VBR; no fixed polarity - enables dual-rail or AC line protection without orientation constraints. |
| Terminal 2 | Anode/Cathode (bidirectional) | Electrically identical to Terminal 1; forms a symmetric two-terminal clamp across protected node and reference (e.g., GND or VCC). |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals, differential buses (e.g., RS-485), or floating power rails without polarity concerns. |
| 600 W peak pulse power | Withstands 10/1000 µs surges up to 5.3 A - sufficient for IEC 61000-4-5 2nd edition 1 Ω/2 Ω source impedance tests. |
| MSL Level 1 moisture sensitivity | Allows unlimited floor life and supports standard lead-free reflow (260 °C peak), eliminating bake requirements pre-assembly. |
| AEC-Q101 qualification option | HE3/HM3 variants available - validated for automotive under-hood and body electronics per stress test requirements. |
| Glass passivated junction | Ensures long-term stability of VBR and low leakage (<1 µA), critical for high-impedance sensor front-ends and battery-powered systems. |
Applications
| Automotive Sensor Interface Protection | Industrial RS-485 Bus Clamping |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ82CA-T | Same VWM (70.1 V), VC (113 V), and SMB package; 600 W rating; manufactured by Diodes Inc. | No AEC-Q101 variant offered; commercial-grade only; lacks Vishay's HE3 automotive suffix option. | Select when cost-sensitive commercial designs require second-source availability without automotive qualification. |
| 1.5KE82CA | Through-hole DO-15 package; same 70.1 V VWM and 113 V VC; 1500 W rating but larger footprint and lower mounting density. | Not suitable for high-density SMT layouts; higher thermal resistance limits repetitive surge duty cycle in compact enclosures. | Choose only for legacy through-hole designs or where higher single-pulse energy absorption justifies board space penalty. |
Compared with SMBJ82CA-T, P6SMB82CA-E3/52 offers direct AEC-Q101 qualification path via HE3 suffix; versus 1.5KE82CA, it delivers identical clamping performance in 40% less PCB area and supports automated SMT assembly without manual insertion.

FAQ
What is the polarity configuration of P6SMB82CA-E3/52?
P6SMB82CA-E3/52 is a bidirectional TVS diode with no polarity marking on the SMB package. Both terminals behave identically under positive or negative overvoltage conditions, enabling symmetric clamping across AC signals, differential buses, or ungrounded power rails without orientation constraints during placement.
Does P6SMB82CA-E3/52 meet automotive qualification standards?
P6SMB82CA-E3/52 itself is RoHS-compliant commercial grade. However, the P6SMB82CA-HE3 variant (AEC-Q101 qualified) shares identical electrical specs and SMB packaging. For automotive use, specify P6SMB82CA-HE3_X (where X = revision code) to ensure qualification per stress test requirements including temperature cycling and HTRB.
What is the maximum clamping voltage of P6SMB82CA-E3/52 under standard test conditions?
The maximum clamping voltage (VC) of P6SMB82CA-E3/52 is 113 V, measured at 5.3 A peak pulse current using the 10/1000 µs waveform per IEC 61000-4-5. This value defines the upper voltage limit imposed on protected circuits during worst-case transient events and must be compared against downstream IC absolute maximum ratings.
How does the SMB package of P6SMB82CA-E3/52 affect thermal performance?
P6SMB82CA-E3/52 in the SMB (DO-214AA) package has a typical junction-to-ambient thermal resistance (RθJA) of 100 °C/W when mounted on 0.2" × 0.2" copper pads. This requires derating above 25 °C ambient per Figure 2 in the datasheet; for continuous 5.0 W power dissipation, forced airflow or additional copper area is recommended to maintain TJ ≤ 150 °C.
Can P6SMB82CA-E3/52 replace unidirectional TVS diodes in existing designs?
No - P6SMB82CA-E3/52 is strictly bidirectional and cannot substitute for unidirectional TVS diodes (e.g., P6SMB82A) in DC-biased applications like power rail-to-ground clamping. Unidirectional types conduct only in reverse bias and block forward current; using P6SMB82CA-E3/52 there would cause unintended conduction during normal operation.
