Product details
Overview
P6SMB170CA-E3/5B from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 170 V standoff voltage (VWM), 234 V clamping voltage (VC) at 2.6 A peak pulse current (IPPM), and 600 W peak pulse power (10/1000 µs). It protects signal lines and power rails in automotive sensor units, industrial I/O modules, and telecom interface circuits against ESD and inductive switching transients.
For engineers reviewing the P6SMB170CA-E3/5B datasheet, P6SMB170CA-E3/5B pinout, P6SMB170CA-E3/5B application, or P6SMB170CA-E3/5B equivalent, key selection criteria include bidirectional clamping capability, 170 V working voltage tolerance, 234 V max clamping under 2.6 A surge, RoHS-compliant matte tin terminals, and MSL Level 1 reflow compatibility up to 260 °C.
Technical Context
This bidirectional TVS operates symmetrically across both polarities with identical VBR (162–179 V), VWM (145 V), and VC (234 V) specifications. Its glass-passivated junction enables fast response (<1 ns) and low incremental surge resistance, critical for suppressing sub-microsecond transients induced by relay switching or lightning surges.
Designed for automated SMT placement on standard PCB pads (0.2" × 0.2"), it delivers 600 W peak pulse power per JEDEC 10/1000 µs waveform at 0.01% duty cycle, with thermal resistance RθJA = 100 °C/W and maximum junction temperature of +150 °C - enabling reliable operation in high-temperature industrial environments without heatsinking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 145 V - maximum continuous reverse voltage before conduction begins; defines operating margin for 120–150 V DC bus protection |
| VBR (Breakdown) | 162–179 V at 1 mA - sharp avalanche onset ensures predictable turn-on during overvoltage events |
| VC (Clamping) | 234 V at 2.6 A - limits transient voltage seen by downstream ICs to safe levels during 10/1000 µs surges |
| PPPM | 600 W - peak surge energy handling capacity compatible with IEC 61000-4-5 Level 4 (4 kV) testing |
| RθJA | 100 °C/W - allows direct mounting on 5 mm × 5 mm copper pads without forced cooling in ambient ≤70 °C |
| TJ max | +150 °C - supports extended operation in under-hood automotive or enclosed industrial enclosures |
| MSL Level | Level 1 (J-STD-020) - qualifies for standard reflow profiles up to 260 °C peak, no dry-pack required |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, bidirectional configuration with no polarity marking; dimensions 4.57 mm × 3.94 mm × 2.20 mm (L × W × H); matte tin-plated leads compliant with J-STD-002 and JESD 22-B102.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (negative polarity) | Conducts surge current when voltage at this terminal falls ≥145 V below cathode; symmetrical with cathode |
| Cathode | Transient current entry (positive polarity) | Conducts surge current when voltage at this terminal rises ≥145 V above anode; identical behavior to anode due to bidirectional design |
Key Features
| Feature | Design Value |
|---|---|
| 600 W peak pulse power (10/1000 µs) | Enables robust protection against IEC 61000-4-5 surge events without derating in typical PCB layouts |
| Glass passivated junction | Ensures stable breakdown characteristics and long-term reliability under repeated transient stress |
| Low profile SMB package | Reduces board space vs. SMA/SMB alternatives while maintaining 600 W rating and automated placement compatibility |
| RoHS-compliant, matte tin terminals | Supports lead-free reflow assembly and eliminates whisker risk per JESD 201 Class 2 |
| AEC-Q101 qualification option (_B suffix) | Validates suitability for automotive applications including engine control and ADAS sensor interfaces |
Applications
| Automotive Sensor Protection | Industrial PLC I/O Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ESD in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector entry point to shunt transients before reaching signal conditioning circuitry. Use Value: Clamps 170 V transients to ≤234 V within nanoseconds, preserving signal integrity and preventing latch-up in 3.3 V/5 V microcontrollers. | Use Scenario: Safeguarding digital input/output channels on programmable logic controllers exposed to motor contactor switching noise and field wiring surges. IC Role / Device Role / Timing Role: Parallel-connected TVS on each I/O line to absorb repetitive 600 W surges without degradation over >100,000 cycles. Use Value: Maintains system uptime by preventing false triggering and component failure in harsh factory-floor electromagnetic environments. |
| Telecom Interface Protection | Power Supply Rail Protection |
Use Scenario: Shielding Ethernet PHYs, RS-485 transceivers, and PoE injectors from lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: First-line defense in multi-stage protection schemes, preceding GDTs or polymer PTCs to handle fast-rising edges. Use Value: Sub-1 ns response time limits let-through energy to <10 mJ, meeting GR-1089-CORE Level 3 surge immunity requirements. | Use Scenario: Guarding 12–48 V DC power rails feeding FPGAs, DSPs, and memory in embedded computing systems. IC Role / Device Role / Timing Role: Standoff-rated TVS placed after bulk filtering but before point-of-load regulators to suppress ripple-coupled transients. Use Value: 145 V VWM provides 20% margin above nominal 120 VAC-derived rails, ensuring no leakage during normal operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ170CA | Same VWM (145 V), identical SMB package, but lower PPPM = 600 W (same rating) and slightly higher VC = 243 V at 2.6 A | Marginally reduced clamping performance; suitable where tighter VC tolerance is not required | Select when cross-referencing legacy SMBJ designs or sourcing from alternate distributors with inventory constraints |
| 1.5SMC170CA | Larger SMC (DO-214AB) package, same VWM/VC, but higher thermal mass and RθJA = 60 °C/W | Better power dissipation in high-ambient conditions, but requires 30% more PCB area | Choose when thermal derating below 70 °C ambient is needed or existing layout accommodates SMC footprint |
Compared with SMBJ170CA and 1.5SMC170CA, P6SMB170CA-E3/5B offers identical surge rating in a lower-profile SMB package with superior MSL Level 1 reflow compliance and verified AEC-Q101 qualification path via _B suffix - making it optimal for space-constrained, high-reliability automotive and industrial deployments.

FAQ
What is the clamping voltage of P6SMB170CA-E3/5B at its rated peak pulse current?
The P6SMB170CA-E3/5B has a maximum clamping voltage (VC) of 234 V at 2.6 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is P6SMB170CA-E3/5B suitable for automotive applications?
Yes, P6SMB170CA-E3/5B is qualified to AEC-Q101 when ordered with the _B suffix (e.g., P6SMB170CAHE3_B). The base P6SMB170CA-E3/5B meets commercial-grade reliability and thermal specs (TJ max = +150 °C, MSL Level 1), and its bidirectional architecture, 145 V VWM, and 234 V VC align with automotive sensor and bus protection requirements.
How does the SMB package of P6SMB170CA-E3/5B compare to SMA or SMC alternatives?
The SMB (DO-214AA) package of P6SMB170CA-E3/5B measures 4.57 mm × 3.94 mm × 2.20 mm - 25% smaller than SMC and 15% smaller than SMA - while maintaining full 600 W surge capability. Its lower profile improves board-level mechanical stability and reduces parasitic inductance, enhancing high-frequency transient response compared to larger packages.
What is the maximum reverse leakage current for P6SMB170CA-E3/5B at its stand-off voltage?
At its 145 V stand-off voltage (VWM), the P6SMB170CA-E3/5B exhibits a maximum reverse leakage current (ID) of 1.0 µA at 25 °C. This ultra-low leakage ensures minimal power loss and no interference with high-impedance sensor or communication circuits during normal operation.
Does P6SMB170CA-E3/5B require special PCB layout considerations?
Yes - for optimal performance, P6SMB170CA-E3/5B should be mounted on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve specified thermal resistance (RθJA = 100 °C/W) and 600 W pulse rating. Short, direct traces to protected nodes minimize inductance and preserve clamping speed; avoid routing sensitive signals near the TVS body.
