Product details
Overview
P6SMB250A-E3/5B from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMB (DO-214AA) package, rated for 250 V standoff voltage (VWM), 263 V minimum breakdown voltage (VBR), and 600 W peak pulse power (10/1000 μs). It provides robust overvoltage protection for high-voltage DC rails in industrial power supplies and telecom infrastructure.
For engineers reviewing the P6SMB250A-E3/5B datasheet, P6SMB250A-E3/5B pinout, P6SMB250A-E3/5B application, or P6SMB250A-E3/5B equivalent, key selection criteria include clamping voltage (344 V at 1.74 A), low leakage (<1.0 μA at 214 V), AEC-Q101 qualification (via -D suffix), RoHS-compliant matte tin terminations, and MSL Level 1 reflow compatibility up to 260 °C.
Technical Context
The P6SMB250A-E3/5B operates as a unidirectional avalanche diode with glass-passivated junction, optimized for fast transient response (<1 ns) and low incremental surge resistance. Its 250 V stand-off rating targets protection of 200–240 VAC-derived DC bus lines against lightning-induced surges and inductive switching spikes.
Designed for automated SMT placement on standard PCB pads (0.2" × 0.2"), it delivers 344 V clamping voltage at 1.74 A peak pulse current under 10/1000 μs waveform, with thermal resistance RθJA = 100 °C/W and maximum junction temperature of +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 214 V - Maximum continuous reverse operating voltage before conduction begins |
| VBR (Breakdown) | 237–263 V at 1.0 mA - Confirmed avalanche onset range for reliable triggering |
| VC (Clamping) | 344 V at IPPM = 1.74 A - Peak voltage seen by protected circuit during 10/1000 μs surge |
| PPPM | 600 W - Surge energy handling capacity per single 10/1000 μs pulse at 0.01% duty cycle |
| ID (Leakage) | <1.0 μA at 214 V - Minimal power loss and signal interference in standby operation |
| TJ max | +150 °C - Enables use in high-temperature environments like enclosed power converters |

Applications
| Industrial Power Supply Protection | Telecom DC Feeder Line Protection |
|---|---|
Use Scenario: Protecting rectified 240 VDC output rails in DIN-rail mounted AC/DC converters against lightning-induced surges and load dump events. IC Role / Device Role / Timing Role: Unidirectional TVS clamp placed across output capacitor to limit transient overvoltage before reaching downstream regulators or controllers. Use Value: Clamps 1.74 A surge to ≤344 V, preventing damage to 400 V-rated electrolytic capacitors and MOSFETs in primary-side snubbers. | Use Scenario: Safeguarding -48 VDC telecom feeder lines from induced surges due to nearby lightning strikes or power cross events. IC Role / Device Role / Timing Role: Standoff-rated TVS connected between feed line and chassis ground to shunt high-voltage transients before entering power distribution boards. Use Value: Withstands 600 W pulses while maintaining <1 μA leakage at 214 V, preserving line integrity during normal operation. |
| High-Voltage Sensor Interface Protection | Motor Drive DC Bus Snubber |
Use Scenario: Shielding isolated voltage sensors measuring 200–250 VDC bus voltages in servo drives from ESD and switching noise. IC Role / Device Role / Timing Role: Front-end TVS on sensor input path to absorb fast-rising transients before isolation amplifier inputs. Use Value: Fast <1 ns response and 344 V clamping prevent latch-up or permanent damage to precision analog front-ends. | Use Scenario: Suppressing voltage spikes generated during IGBT turn-off in 200–250 VDC motor inverters. IC Role / Device Role / Timing Role: Parallel-connected TVS across DC link capacitors to clamp dV/dt-induced overshoot during high-current switching. Use Value: 600 W rating handles repetitive switching surges; low Rsurge ensures minimal voltage overshoot beyond 344 V. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ250A | Same SMB package, identical VWM/VBR/VC specs, but rated for 600 W with tighter VBR tolerance (5%) vs. P6SMB250A's 10% | Preferred where tighter breakdown consistency is critical for predictable clamping threshold | Select SMBJ250A when statistical control of VBR is required in high-volume production test plans |
| 1.5SMC250A | Larger SMC (DO-214AB) package, same electrical ratings, higher thermal mass (RθJA ≈ 60 °C/W), 1500 W peak power rating | Better suited for high-repetition-rate surges or elevated ambient temperatures where SMB thermal limits are exceeded | Choose 1.5SMC250A when board space allows and thermal derating margins are insufficient with SMB footprint |
Compared with SMBJ250A, P6SMB250A-E3/5B offers broader VBR tolerance and lower cost for applications tolerant of ±5% variation; versus 1.5SMC250A, it trades thermal headroom and peak power for compact SMB layout-ideal where PCB area is constrained but single-event surge protection suffices.

FAQ
What is the clamping voltage of the P6SMB250A-E3/5B under a 10/1000 μs surge?
The P6SMB250A-E3/5B clamps to a maximum of 344 V when subjected to its rated peak pulse current of 1.74 A under the standard 10/1000 μs waveform. This value is measured at the device terminals and represents the upper voltage limit imposed on the protected circuit during transient events. The P6SMB250A-E3/5B achieves this with low incremental surge resistance, ensuring consistent performance across production lots.
Is the P6SMB250A-E3/5B RoHS-compliant and lead-free?
Yes, the P6SMB250A-E3/5B carries the "E3" suffix, indicating full RoHS compliance and lead-free construction per EU Directive 2011/65/EU. Its matte tin-plated terminations meet J-STD-002 solderability requirements and JESD 22-B102 whisker testing Class 2. The P6SMB250A-E3/5B is also compatible with lead-free reflow profiles up to 260 °C peak temperature (MSL Level 1).
Does the P6SMB250A-E3/5B have automotive qualification?
The base P6SMB250A-E3/5B is not AEC-Q101 qualified; however, Vishay offers the P6SMB250AHM3_D variant (halogen-free, RoHS-compliant, and AEC-Q101 qualified) for automotive applications. The "D" suffix denotes AEC-Q101 qualification for the 250 V to 540 V range. Engineers specifying P6SMB250A-E3/5B for automotive use must migrate to the HM3_D version to meet qualification requirements.
What is the maximum reverse leakage current for the P6SMB250A-E3/5B at its stand-off voltage?
At its maximum stand-off voltage of 214 V, the P6SMB250A-E3/5B exhibits a maximum reverse leakage current (ID) of 1.0 μA at 25 °C ambient temperature. This ultra-low leakage preserves system efficiency and avoids false triggering in high-impedance sensing or monitoring circuits. The P6SMB250A-E3/5B maintains this specification across its full operating temperature range, with minor increase only above 100 °C.
How does the P6SMB250A-E3/5B compare to bidirectional TVS diodes in the same series?
The P6SMB250A-E3/5B is unidirectional and intended for DC line protection with defined polarity; bidirectional variants (e.g., P6SMB250CA) are used for AC or floating signal lines. Unlike bidirectional types, the P6SMB250A-E3/5B has a cathode band marking and conducts forward current below ~1.5 V. Its VWM and VBR ratings apply only in reverse bias-forward conduction is not a protected mode. The P6SMB250A-E3/5B cannot substitute for a bidirectional device without circuit redesign.
