Product details
Overview
P6SMB30AHE3_B/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on power and signal lines. It features a 30 V standoff voltage (VWM), 31.5 V maximum breakdown voltage (VBR), 41.4 V clamping voltage at 14.5 A peak pulse current, and 600 W peak pulse power capability with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial power supplies.
For engineers reviewing the P6SMB30AHE3_B/H datasheet, P6SMB30AHE3_B/H pinout, P6SMB30AHE3_B/H application, or P6SMB30AHE3_B/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 150 °C max junction temperature, low incremental surge resistance, and compatibility with automated SMT assembly on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates as a clamping device that remains non-conductive below its 30 V stand-off voltage and rapidly transitions to low-impedance conduction above its 31.5 V breakdown threshold. Its glass-passivated junction ensures stable leakage performance (<1.0 μA at VWM) and fast response time (<1.0 ns).
The device delivers 600 W peak pulse power handling under 10/1000 μs waveform with 0.01% duty cycle, and is rated for 100 A non-repetitive forward surge current (8.3 ms half-sine). Thermal resistance is 100 °C/W junction-to-ambient (RθJA) and 20 °C/W junction-to-lead (RθJL), supporting operation from –65 °C to +150 °C.
Key Specifications

| VWM (Stand-off) | 30 V - Maximum continuous reverse operating voltage before clamping begins |
| VBR (Breakdown) | 28.5–31.5 V at 1.0 mA - Confirmed breakdown range ensuring reliable turn-on margin |
| VC (Clamping) | 41.4 V at 14.5 A IPPM - Peak voltage seen by protected circuit during transient event |
| PPPM | 600 W - Surge energy absorption capacity per 10/1000 μs waveform |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Suppressing load-dump transients (up to 35 V, 100 ms) on 12 V battery-fed ECUs. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VBAT and GND to clamp overshoot before it reaches LDOs or microcontrollers. Use Value: Prevents latch-up or permanent damage to 3.3 V/5 V logic circuits while maintaining <1.0 μA leakage at nominal 12 V operation. |
Use Scenario: Protecting analog outputs (e.g., 4–20 mA current loop drivers) from field-wiring ESD and inductive kickback. IC Role / Device Role / Timing Role: Clamping diode across output terminals to limit voltage excursion during cable disconnect or relay switching. Use Value: Ensures signal integrity remains intact with ≤41.4 V clamping during 14.5 A surge, preserving DAC and op-amp functionality. |
| Consumer Power Adapter Input Stage | Telecom DC Power Feeds |
Use Scenario: Secondary-side surge protection in AC/DC adapters subjected to IEC 61000-4-5 Line-to-Ground surges. IC Role / Device Role / Timing Role: Fast-response TVS shunting transient energy away from rectifier and primary controller feedback paths. Use Value: Withstands 600 W pulses without derating at TA = 25 °C and maintains <100 °C/W thermal resistance for compact PCB layouts. |
Use Scenario: Protecting -48 V telecom power distribution boards from lightning-induced surges on backplane feeds. IC Role / Device Role / Timing Role: Standoff-rated TVS installed at board edge to divert common-mode transients before reaching PMICs and FPGAs. Use Value: 30 V VWM allows safe operation on -48 V systems with sufficient margin; 150 °C TJ rating supports sealed enclosure deployment. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ30A-E3/5B | Same SMB package, 30 V VWM, but only commercial-grade (not AEC-Q101 qualified); 41.3 V VC at 14.3 A | Lacks automotive qualification; suitable for consumer/industrial where AEC-Q101 not mandated | Select when cost sensitivity outweighs automotive reliability requirements |
| 1.5SMC33A | Higher 33 V VWM, 36.7 V VBR, 49.9 V VC; same 600 W PPPM but larger SMC (DO-214AB) package | Requires PCB layout change due to larger footprint; better suited for higher-voltage rails (>30 V) | Choose only if system requires ≥33 V standoff and board space permits SMC package |
Compared with SMAJ30A-E3/5B and 1.5SMC33A, P6SMB30AHE3_B/H uniquely combines AEC-Q101 qualification, precise 30 V standoff, and SMB footprint - making it the preferred choice for space-constrained automotive modules requiring validated reliability.

FAQ
What is the clamping voltage of P6SMB30AHE3_B/H at its rated peak pulse current?
The P6SMB30AHE3_B/H has a maximum clamping voltage (VC) of 41.4 V at 14.5 A peak pulse current (IPPM) under 10/1000 μs waveform conditions. This value is measured per JEDEC standards and reflects the actual voltage imposed on protected circuitry during worst-case transient events - critical for verifying margin against downstream component absolute maximum ratings. The P6SMB30AHE3_B/H maintains this clamping performance across its full operating temperature range.
Is P6SMB30AHE3_B/H suitable for automotive applications?
Yes, P6SMB30AHE3_B/H is AEC-Q101 qualified and explicitly designated for automotive use via the "HE3" and "_B" suffixes. It undergoes stress testing including temperature cycling, highly accelerated life testing (HALT), and surge endurance per AEC-Q101 Rev D. The P6SMB30AHE3_B/H is deployed in engine control units, body electronics, and ADAS power domains where sustained reliability under thermal and electrical stress is mandatory.
How does the P6SMB30AHE3_B/H differ from bidirectional variants like P6SMB30CA?
The P6SMB30AHE3_B/H is unidirectional, with cathode marked by a band and intended for DC line protection where polarity is fixed (e.g., VBUS-to-GND). In contrast, P6SMB30CA is bidirectional, lacks polarity marking, and clamps symmetrically in both directions - suitable for AC-coupled or floating signal lines. The P6SMB30AHE3_B/H offers tighter leakage control (<1.0 μA) and is optimized for single-polarity surge suppression in power rails.
What is the thermal resistance of P6SMB30AHE3_B/H, and how does it affect PCB layout?
P6SMB30AHE3_B/H 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 minimum recommended pad layout per Vishay specification; reducing pad area increases thermal resistance and risks exceeding 150 °C junction temperature during repetitive surges. The P6SMB30AHE3_B/H must be placed with adequate copper pour and avoid thermal isolation to sustain its 600 W pulse rating.
Can P6SMB30AHE3_B/H replace older P6SMB30A-E3 parts in existing designs?
Yes, P6SMB30AHE3_B/H is a direct form-fit-function replacement for P6SMB30A-E3 in most cases: identical SMB package, same electrical characteristics (VWM = 30 V, VBR = 28.5–31.5 V, VC = 41.4 V), and compatible soldering profile. The key enhancement is AEC-Q101 qualification and improved traceability via the "HE3_B/H" ordering code. No PCB changes are required, and the P6SMB30AHE3_B/H provides extended reliability assurance for new production runs.
